Drip irrigation for your garden




Drip irrigation is the most efficient and economical way to water your garden, saving you time, money and water.

What is drip irrigation?

It is an efficient and economical irrigation method. This irrigation method gives more than 90% efficiency of the water used. Unlike sprinkler irrigation methods, which are only 65-75% efficient, drip irrigation reduces leakage and evaporation. Drip irrigation delivers water very slowly to the root of the plant, just where it is needed.

Drip irrigation is used in greenhouses, nurseries and agricultural firms. Be that as it may, ordinary home owners can take advantage of the use and benefits of drip irrigation... As a homeowner, you can use drip irrigation for your vegetable and year-round gardens, trees, flower beds, and flowers.

The benefits of drip irrigation

Tubes with a lot of droppers, called drip lines, are placed above the ground along the plant beds. Droppers slowly let water into the soil at the root zone. As the moisture level is kept at an optimal level, the plant's growth productivity and quality are improved. Plus, drip irrigation:

Prevents disease by minimizing water contact with plant leaves, stems and fruits.

Allows the beds between plants to be dry, improves access and reduces weed growth.

Saves time, money and water thanks to its highly efficient system.

Reduces labor costs.

Increases efficiency even on uneven surfaces.

Reduces water leakage and fertilization below the root zone.

Drip irrigation system assembly and components.

Main components drip system are faucet or automatic controller, filter, main line, auxiliary lines, connectors and fittings, drip lines and plugs.

The main line is connected to a water source - to an external tap - and then, through an auxiliary line, to drip lines. Basically, construction lines are used if you have many watering zones. The total length of the main line and auxiliary lines should be no more than 120m.

The tap regulates the water supply to the system and can be controlled either manually or automatically (if an electrical controller is connected). A pressure regulator is required if the pressure can exceed 2 bar.

Filters prevent droppers from clogging up with substances undissolved in water during a long time of use. It is best if the filter has a filter mesh of at least 120 MESH or higher. Adapters and filters are used to connect drip lines to the remainder of the system. This is important as it is the correct size to prevent leakage when pressurized water supply.

Drip lines and drippers

The drip line is a polyethylene tube with built-in drippers that should be located near the plants. Drip lines and droppers come in different types and diameters depending on your needs. The length of each drip line 16 mm / 33 cm / 2.1 l / h should not exceed 50 m from the point where the water enters the tube so that the emission uniformity is 95%. You will need to reinforce the line to prevent it from moving.

Typical mistakes

The following points are provided to introduce you to some typical mistakes that are encountered in the design and installation of a drip irrigation system.

Too long drip line or too many droppers:

The Tandem drip line contains drippers that are pre-installed at the factory every 33 cm and each dripper consumes 2.1 l / h (at 1 bar pressure)

The maximum recommended length is about 50 meters on a flat surface in order to have an equal flow with 95% uniformity or a maximum of 80 meters for 90% uniformity of flow, which already means that an emission difference of up to 15% is possible between the first and last dropper in the line ... Since the Tandem drip line has 4 outlets per drip chamber, this contributes to better flow and better stability against clogging.

Filtration:
Use the correct filters for your system. Choose the right filter element for your water quality and drip type. We recommend a filter with a mesh of at least 120 MESH. Never use the system without filters.
Incorrect pressure:
In order for the drip system to function properly, it must be supplied with the correct pressure. (BAR or ATM are the same) If you try to put too many IVs in the line, the pressure will drop below the minimum operating minimum and your system will not work. If you are using the wrong pressure regulator or not using one at all, your system will be too pressurized and will not work properly. The table below shows the different flows with different pressures and relative diagrams.




... Incorrect zoning:
"Zoning" is a grouping of a large drip line in common "zones". Zones are usually grouped by plant type. The trees are separated from the flower beds. Plants that are resistant to dry climates are separated from moisture-loving ones, etc. if you have different types soils, you can also separate them into separate zones. The main thing that you should remember is the ability to water each plant according to its needs when the system is on? If you place a large tree on the same line as a small flower bed, one of them will be either too dry or too wet.
... The drip irrigation system can be connected via an automatic regulator.
Since a small amount of water is delivered slowly, drip irrigation is designed to function throughout the day, excluding rainy days. The question of how long to use drip irrigation depends on how much water your plants require per day and how much the drip outlets have. Water is served once or twice a day. Best time for watering - early in the morning, because at this time the level of evaporation is lowest.
... Water Demand: You should know the water demand according to the evapotranspiration factor (Evaporation rate in the area you are in and plant transpiration). If, say, the total evaporation is 5 mm per day in the hottest month, we calculate this data according to the size of the zone we wish to water, i.e. 100m2: 100m2x 0.005m = 0.5m3 per day is the water demand every day. This is an accurate calculation of the amount of water you need to apply each day through the drip system. You can water every two days, doubling the amount of irrigation water, or even every 3 days, tripling the amount of water. You also need to adjust the system in months that are not so hot.
The usual way to do this is through trial and error. Adjust system usage times and daily schedule for the entire season. The main thing is the need to observe the plants and pay attention to their needs. You need to do more than just install the drip system and go into the house. You should check your system periodically to make sure it works fine.
Beginning of work

If this is your first time installing a drip system, we recommend trying one of the kits. Each kit contains everything you need to install a working drip irrigation system. All parts can be purchased separately to be added to the system later.
The components of the drip system are the following: controller, valves, filters (pressure regulator if pressure exceeds 2 bar), drip fittings, drip line (micro pipes) (drippers), and scissors and tweezers type tools.
... The Greentimer is a battery powered controller: it has an all-in-one design that can be hung directly on a bell or other water source. This type of controller is ideal for small systems in one irrigation zone.
... The ideal working pressure for your irrigation system is 1 bar for drippers or 1.2 bar at the starting point of the water supply (If your pressure is more than 2 bar, use a pressure regulator to reduce the high pressure).
... If you leave polyethylene pipe size of 16 mm in the sun, it will be easier for you to work with it.
... If you have a problem trying to insert the ½ ”prongs into a 16mm pipe, then placing the pipe in warm water will make the process easier. You can also heat the tube ends using a hair dryer.
The diagram below gives a visual representation of how to assemble each type of system:
... A drip irrigation system using a bell and battery powered controller (timer), filter, 16 mm polyethylene pipe, 16 mm drip line with droppers inserted every 33 cm, produces a flow of 2.1 liters per hour at a pressure of 1 bar.


Note: When connecting your components, be sure to use the correct thread and apply some insulation to it to avoid water leakage.

Place insulating tape around the threaded connection of the Greentimer controller

Screw the insulating foil around the filter thread

Connect the coupling


Screw the insulating tape around the threaded connection of the inlet nipple


Insert the connector into the 16mm pipe, fix the connector

Unscrew the 16mm tube and cut when it reaches ground level

Connect the elbow to the other end of the 16mm tubing and then to the drip line

Connect the Tandem drip line to the knee. Install a Tandem drip line along the line of your plants

Use a T-piece to follow the contour of your plants

Close the end of the drip line by bending the tubing and installing the double clamp

Planning your system

Start by making a sketch of the area you want to water. Make sure to include locations for trees, bushes, vegetables, and natural shelter. Prepare a list of your plants by category, i.e. natural shelters, bushes and trees. Based on plant size, category and density, you can determine the required flow rate for the droppers. Show on paper the location of the site's water resources, obstructing walls and paved areas. This will require measuring the area you want to water.
Planning for future use
In any project you create, leave room for future expansion. As plants mature, they may require more water. Watering times can be extended to meet this need, but in general, more drip lines need to be added to ensure growing plants. In addition, new plants can be added to the landscape, therefore, leave room in the overall project, taking into account the increase in the volume of the available water supply by 20-30%.
Setting up your system
Installing a drip irrigation system is a fairly simple process. Start by comparing your plan to the actual landscape and make any necessary adjustments to your plan to reflect the actual conditions at the site. Begin installation and assembly at the water source. If the drip system is serving more than one zone, then by adding valves to each drip tube you achieve control of each zone. If you choose to automate your system, your controller should be the first component in your build.
Installation of drip lines
Install drip lines using fittings as needed. Don't lay the lines too tightly; leave room for expansion and contraction due to changing weather conditions. Make it possible for larger plants to receive more water by adding more drippers (more drip line meters). You can draw a line around the tree to provide more drippers.
The first start of the system
Before turning on the system for the first time, leave all ends of the drip lines open, turn on the water supply and allow it to flow freely for a few minutes. This will flush out any dirt that may be inside the line. Close the ends of the drip line using plugs. Make sure the drippers are working properly and there is no water leakage at the connection points.
Service
... Inspect the droppers to make sure they are not clogged.
... Filters should be rinsed and cleaned at least once a month, depending on the quality of the water. By checking the filters one week after installation, you will get an idea of ​​how often to schedule filter cleaning.
... It is also necessary to periodically flush the line tubes; again, water quality will be a decisive factor in determining the frequency of flushing.
... During cold weather, we recommend draining the water from the plastic tubes or rolling them up and putting them in storage.
... During cold weather, we recommend removing the battery-powered controller and, having completed a complete disassembly of the equipment (filters, valves), put them in storage indoors.
... Once a year, remove plugs or open hose ends to flush the line.
... As the plants grow, you may need to add, change, or remove drip lines.
To better manage your irrigation process, you should know:
Determination of soil type
When water is slowly applied to the root zone at one point, it is subject to gravity (downward movement) and capillary action (outward movement), creating a characteristic of wetted soil type and irrigation rate. To determine what type of soil you have in your area, take a handful of dry soil, squeeze lightly and release. Sandy (rough) soil will crumble and fall apart. Loam (medium density) will stick together but can be easily broken. The clay is compressed without breaking.

Each soil type will require a separate layout. On sandy soil, water tends to seep down, so we recommend using closely spaced or large volume drippers. In loam, the water will move slowly and spread evenly, so you can use fewer drippers with more distance between them.
Tandem Drip Line with outlets on both sides of the drip chamber provide faster flow and better distribution of irrigation water.

The relationship between soil and water
Capillary moisture is water held in pores by the surface tension that exists between the water and soil particles. Capillary moisture is the primary force that distributes water horizontally and is the primary source of water for the plant.
Gravity water is free water in the soil that flows downward under the influence of gravity. After the soil is saturated with water, gravity water seeps down, leaving the soil at the field capacity

EXAMPLE OF GOOD IRRIGATION UNIFORM


WASTE WATER


Field moisture capacity is a method of measuring the volume of water retained in the soil despite the action of gravity. If the soil is saturated with rain or watering and then dries freely within 24 hours, the soil is usually at the field water capacity.

For most plants, soil moisture content, which is at the field moisture capacity, is the ideal moisture level for vegetative growth, since there is a good balance between soil moisture saturation and weathering. The soil will lose a small amount of water after it dries out to field capacity if there are no plants on it. Plants will remove water through transpiration and reduce moisture in the soil. On hot days, plants can use water faster than the soil can supply the roots, or faster than the roots can supply the rest of the plants, and the plant will wither. Usually, with sufficient moisture in the soil (which you can maintain with your irrigation system), the plant will recover overnight.
The point of persistent wilting is the moisture content in the soil at which the plant wilts and remains wilted.

Calculation of the total volume of consumption
To determine the total flow rate in the area of ​​the drip system, simply add the total number of drippers and their flow rate.
Example: You have designed a system using a 50 meter long Tandem drip line, the drippers are spaced every 33 cm and the flow rate is 2.1 liters per piece (on each dripper). 50 m divided by 0.33 m = 152 droppers multiplied by 318 liters per hour.
When in doubt about the capacity of your water source, measure how long it takes to fill a bucket of known volume. For example, it takes 20 seconds to fill a 5 liter bucket, then the maximum water flow per hour is 5 liters multiplied by 3 = 15 liters per minute x 60 minutes = 900 liters of water per hour. If the system requires more water, separate the system by adding another valve. The maximum recommended flow rate for a 16 mm drip line is 800-900 liters.

Today, to facilitate the care of plants, various irrigation systems are used, they make it possible to control the amount of water for each type of plant, apply drip irrigation or sprinklers. Water is saved, the most favorable conditions for development are created for plants. The only drawback of such systems is the need for constant monitoring, switching on / off is done manually. This is a rather unpleasant activity, the duration of watering, depending on the type of plant, climatic conditions and a specific system can be up to two hours. In order to solve this problem, you should install a watering timer for gravity systems.

First, you need to explain the concept of "gravity systems", otherwise in some sources you can find amusing explanations of the principles of their operation and a complete lack of understanding of hydrodynamics.

Automatic watering systems for the garden - diagram

There are experts who claim that irrigation timers for gravity systems are so good that they can work with water pressures from 0 to 6 atmospheres. They will work at zero pressure, only nothing will be watered. Gravity is not a physical concept, but a purely everyday one. And it means not the absence of pressure, but the absence of constantly operating water pumps. In gravity systems, the pump supplies water only to the storage tank, which is located at some distance from the ground. Due to the height difference between the upper level of the water and the place of its exit, pressure is created, it is this pressure that makes the water flow move.

Why are timers used in most cases for gravity systems? Because they cannot operate at high pressures, their closing valves are too fragile and their drive mechanism is weak. For most devices, the maximum water pressure cannot exceed 0.5 atm., For such a pressure, a container with water should be at a distance of five meters from the earth's surface. The vast majority of irrigation systems have storage tanks located much lower.

Timer types

Three types of timers are currently available for purchase:

  • mechanical. The simplest are semi-automatic control systems. Switching on is performed manually, switches off automatically after a specified period of time (up to 120 minutes). Does not require power supplies, the closing valve is spring-operated. The advantages are low cost and high reliability. Disadvantages - you cannot do without the presence of people during switching on;

  • electronic with mechanical control. Watering modes are fully automated, the watering schedule can be adjusted for a seven-day period, the duration of watering is up to 120 minutes. Advantages - relatively low cost, ease of programming and management. Disadvantages - inability to connect additional equipment;

  • electronic with programmed control. The most modern devices have the ability to set up to 16 special functions. Disadvantages - high cost. In addition, it can be difficult for untrained users to install programs.

Mechanical timers are rarely used, most often irrigation systems are controlled by one of the types of electronic devices. The water supply is regulated by a solenoid (electromagnetic) valve or a ball valve.

Timer for watering on 2 lines, mechanical "Expert Garden"

  1. Solenoid valve. At a certain time, power is supplied to the electromagnetic coil, under the influence of electro magnetic field the core is pulled into the solenoid and shuts off the water flow. If the power supply is interrupted, the core is pushed upwards by the spring and the pipe lumen opens. In timers, the principle of operation can be reversed - without tension, the valve is closed by a spring, and when a strong magnetic field occurs, it opens. Due to this principle of operation, battery power is saved. The operation of the solenoid valve can be distinguished by a characteristic click during opening / closing.
  2. Ball valve. Opening / closing is performed by a gearbox driven by an electric motor. To save power, it is also constantly in the closed position, opens only for the period when the system is turned on for irrigation. A short operating noise is heard during the timer with the ball valve electric motor and gearbox.

Important. As soon as there are risks of frost, the timer must be turned off. Why? During start-up, large currents appear in the stator windings, as soon as the rotor begins to rotate, the current drops to operating modes. During frosts, the ball valve may freeze a little, the power of the electric motor is not enough to break it off. This means that starting currents will flow through the windings for a long time, which will inevitably lead to their overheating and short circuit. And the gearbox itself is not designed for significant efforts, the drive gears may fail. Such malfunctions require complex repairs or complete replacement of the device.

Mechanical electronic timers (tumbler type)

Very easy to operate, reliable and durable devices. To select the operating modes of the irrigation system, you need to perform the following steps:

  • unscrew the top transparent plastic cover... You need to work carefully, do not lose the sealing gasket, it may fall out;
  • use the left toggle switch to set the frequency of turning on the system, the maximum period is 72 hours;
  • with the right toggle switch, set a specific watering duration, maximum 120 minutes.

Important. The initial countdown time of the electronic device starts from the time the timer is turned on. This means that if, for example, you want watering to be switched on periodically at five o'clock in the morning, then the first timer setting must be done at the same time. In the future, the time for turning on the irrigation system will not change.

Manufacturers complete with a timer implement a complete set of fittings for connection plastic pipes or flexible hoses of various diameters. The timer is powered by two AAA 1.5 V AA batteries.

Electronic timers with software control

More modern devices have significantly advanced functions. The delivery set includes adapters for connecting pipelines and flexible hoses of various diameters. Configuring software control is performed as follows:

  • remove the plastic cover. It is twisted quite tightly at the manufacturing plant, considerable efforts will have to be made;
  • press the Time button, the program installation parameters will appear on the electronic board. Install current time and the day of the week, the action must be confirmed by pressing the Set button;
  • in turn, go to each day of the week, choose the time and duration of inclusion electronic timer... These parameters will be saved for the entire period of use;
  • if desired, up to 16 different programs can be configured on the device. To do this, press the Prog button and then set the required number of programs. All entered data must be confirmed by pressing the Set button.

A rather capacious capacitor is installed inside the device. It is designed to signal a critical discharge of the batteries and switch the timer to autonomous power mode. When the battery power is low, a warning signal will appear on the display. From the time of its appearance, the batteries can still work for 2-3 days, depending on the frequency and duration of the irrigation system.

In fully autonomous mode, the condenser can provide a timer for 3-4 days. If the batteries are not replaced during this time, the timer will be canceled. After that, all previously set watering modes will be erased from memory, you will have to repeat the installation steps from the very beginning.

In standby mode, the timer consumes no more than 1.2 mA, during operation, the current consumption increases to 350 mA. These are very small values, allowing the device to operate on batteries alone for at least a season. Manufacturers deliberately left this time, during the period of the annual routine inspection of the irrigation system before starting it is recommended to install new batteries.

There are models of timers designed to work on large and complex irrigation systems. They have several valves, which allows you to control the irrigation modes of several separate zones, for each of them its own parameters are set. Multi-valve devices can be connected to a voltage of 220 V or have up to eight AAA 1.5 V batteries.

What data should be taken into account when configuring sensors

The conditions for growing plants largely depend on the correct setting of the timer program. What should be considered?

Breakdown of the irrigation area into separate zones, taking into account the types of crops. Each of them has its own requirements, in some cases you will have to buy multi-valve timers.

Hydraulic calculation based on the maximum water consumption. Timers should take into account the total storage capacity. If there is no automatic pumping, then you need to independently control the presence of water and, if necessary, fill the containers.

Analysis of the trace of the laying of irrigation systems. Large differences in the height of individual irrigation lines can have a significant impact on their productivity. When setting up, you should keep in mind not only the watering time, but also the amount of water that is supplied to the plants during this time.

After completing the installation of the timer, it is recommended to check the functionality of the system. For this, the minimum switching periods are set, the correct operation of the valve drives is checked. If the timer is in normal mode, you can start specific programming and put the system into automatic mode of operation.

The process of installing the timer program will be much easier if you purchase additional sensors along with it.

Additional timer features

Electronic timers for watering with sensors can perform several additional functions, which further simplify the process of growing crops in greenhouses or on open ground.

  1. Rain sensor. Such equipment is used during the installation of irrigation in open areas. The rain sensor sends a signal to electronic device about the presence of natural precipitation. The timer reacts to these signals and skips one watering, which coincides with the period of rain. The sensor is adjustable in the rainfall range from 3 mm to 25 mm. This wide range allows you to more accurately adjust the irrigation rates based on weather conditions. The presence of the function of an accelerated recall allows you to stop watering in the shortest possible time after the start of rain, the devices do not require additional maintenance. Depending on the settings of the ventilation ring, a delay is set for returning the dacha to standby mode. The return time to its original position is directly dependent on the humidity and ambient temperature. This allows significant water savings to be achieved.
  2. Diaphragm pump. It can be mounted in a joint with a timer or in a separate housing, monitors the water level in storage tanks... When the amount of water decreases below the critical level, the pump is automatically turned on to replenish the reserves. After filling the tanks, the pump turns off.
  3. Radio channel soil moisture sensor. The most modern device, greatly facilitates the care of plants. Installed in several places on the beds, it blocks the timer command for irrigation in case of high soil moisture. The most modern devices increase crop yields by at least 10%.
  4. Water purification filter. Performs high-quality water purification, significantly increases the timer operation time.

Additional monitoring and control devices can be purchased together with the watering timer or separately.

Drip irrigation and watering timers: what is it and where and what to use it for?

Drip irrigation- this is the most perfect way of watering plants in the beds in small doses, while:

  • 🏜️ without eroding the soil, without creating soil erosion
  • 🌿 without feeding the weeds with moisture, water is supplied only to the grown plant
  • 💦 saving water
  • 🌊 without creating an excess of moisture
  • 💪 saving your arms, shoulders, back - after all, you no need to carry watering cans

What is drip irrigation and its automation in simple words

  • take a barrel of water
  • place it above 80 cm above ground level
  • connect a timer to it (so as not to water the whole day, but on a schedule)
  • and to the timer - a special hose for drip irrigation
  • run this hose between your plants
  • pierce the hose near the plant sprouts, lay down to the plant and insert the dropper.

and that's it!

You just have to add water to the barrel ( better pump) and weed.

Where did drip irrigation come from and the scope of its use:


Drip irrigation in modern world considered an invention of Israeli farmers who still manage to supply vegetables and fruits from their arid greenhouses around the world(including Russia). Although, the type of watering appeared much earlier, just a sample modern work Israeli specialists have become a role model for many other manufacturers.

The essence of the simple operation of drip irrigation is described above, but it is important to understand that its application is so universal that it is suitable for the entire garden: from watering strawberries in the open field to greenhouse plantings.

Optionally:

★ All from one barrel.
★ "By gravity".
★ With a set interval.
★ C control, soil and whether it rained.

Price and types of irrigation systems

By water supply source:

    • drip- from the water source (under pressure, "passive system": from the barrel by gravity) through the main hose with outlets to the plants through the "droppers"

Drip irrigation kits prices

Please note that for a start, the price depends on the length of the main hose and the number of bends with droppers: from 10 to 18 m (for 30 or 60 plants).

Such sets cost from 1000 to 2000 rubles. There are also additional kits for expanding the standard configuration, for example, "AquaDusya +12".

And when and how does the automatic irrigation switch on and the options for its application?

Yes, what matters is WHEN to turn on watering. It's not for you to walk with a watering can or a hose for irrigation, but just after a few days of absence from the country, come and see that all the plants and trees are watered.

First you need to solve a few simple calculations:

  • how many zones for irrigation on your summer cottage you choose
    Example    : you have 2 beds of 6 meters each, 1 greenhouse with 2 beds of 6 meters, a lawn for watering, 2 fruit trees for watering. So you have 4-5 irrigation zones
  • how much moisture is needed for irrigation
    With "gravity" from the barrel (and this, depending on the height of the barrel with water above the ground, can be from 0.5 to 2 atm) with drip irrigation per 1 dropper (per 1 plant) for 80 minutes. on average 2-3 liters of water are consumed. Depending on what kind of plants you have and the given mode of watering them, the choice of how much water for irrigation will depend on.

For example, in accordance with GOST, the watering rate is 3-6 liters, depending on the soil, and on a hot day - 10 liters per 1 sq.

DETAILS
Question: What height to choose for the installation of the "gravity" barrel?
Answer: In most cases, for a 200-250 liter barrel, a lifting height of 80 cm to 1.5 m above the height of the irrigated area is sufficient.

  • decide on a watering timer

IT'S IMPORTANT TO KNOW :
such irrigation automatics are divided into " timers"and" programmers ", although most often referred to as" watering timers ".

The difference is that the timers simply "set the cycle", most often they set the watering interval by day for a week (eg 2 days in hours) and with the duration of watering (eg 60 minutes). BUT programmers (controllers) are able to set both interval and duration up to date and time.

What are the watering timer

  1. There is watering timers, which are simply already included in the kit drip irrigation kit. For example, in drip irrigation kits BEETLE for 30 and 60 plants.
  1. There is separate timers, for example, the famous Israeli brand Green Helper and the Russian brand Termovent (both brands are made in China)
  1. There is watering timers and programmers, which include many useful functions (sometimes included, and sometimes additionally connected): rain sensors (soil moisture), several service areas for irrigation, built-in pumps, more than 10 programs for irrigation, etc.

GARDEN PARTNERSHIP ROSS, APRELEVKA Reliability Already for 6 months we have installed the Eurolos wastewater treatment system. Although the installation is not cheap, it absolutely suits us, since during the time of use there were no reasons for complaints. Before Eurolos, we had an ordinary cesspool, and of course these are incomparable concepts. Firstly, before we constantly monitored the level, and periodically carried out cleaning, but now this is not necessary. It is really very comfortable and frees you from unnecessary problems. I highly recommend purchasing this rig, as this is not a case where it is worth saving. I think you understand. And I wish the EuroLos employees success in their work and also provide services only at a high professional level. IGOR 5 May 2015

At first, some questions arose, I wanted to figure it out a little myself, so I was looking for answers on the net. I did not expect that by calling the company, I would receive a detailed answer. I mean, not trivial memorized phrases, but quite professional patronage, recommendations and personal observations were given. Everything is very human, but on a professional level, for which thanks to your team. IVAN AND FYODOR MIKHAILOVICH SAMOILOV 23 January 2015
