CJSC"Tiraspol Cereal Complex" introduces innovative solutions for irrigation of agricultural crops

Irrigation is one of the main factors in the intensification of agriculture in areas with insufficient and unstable moisture.

Long-term meteorological observations in nearby countries confirm that the territory of the Pridnestrovian Moldavian Republic is under the influence of a relatively arid climate. Statistics on droughts confirm that they occur at least once every three years, but in the last two decades, droughts have formed much more often and are more intense.

According to experts, guaranteed harvest of the main agricultural crops cultivated in the republic in conditions of drought is possible only on irrigated land plots. Therefore, it is necessary to maximize the use of irrigation of agricultural lands as an element of the technological process in order to prevent a decrease in crop production and, as a result, ensure food security of the republic.

Thus, as part of the plan to increase the irrigated areas of agricultural land, Urapivot remote irrigation systems have been purchased, which allow you to control the irrigation mode without the participation of an operator from a tablet or smartphone. The Urapivot system is equipped with special sensors that stop watering at low mains voltage, low water pressure in the system. It is also possible to schedule watering for several weeks, which allows you to automatically start watering at a given rate at the required time.

A subsurface irrigation system was also purchased.

Subsurface drip irrigation, known as SDI, is an irrigation system in which a drip line of polyethylene pipes is supplied to the subsurface to drain water into the root zone of the plant. Why is it good? The main advantage of SDI is that the land user can more accurately manage the watering of the root zone. This means lower evaporation losses and the ability to introduce nutrients through irrigation.

The underground drip irrigation system also allows for underground irrigation in irregularly shaped fields. In addition, it allows the land user to meet the different water needs of different soils and crops.

How SDI works The main design of the underground irrigation system is a drip line buried in the soil. It should be located below the aeration depth, at least 6-12 inches below the slope. The SDI drip line will have small holes, called emitters, evenly spaced along its entire length. The water pressure inside the tube pushes the water out of the radiators drop by drop. The distance between the emitters depends on the type of soil and how it holds water.

The amount of water is regulated by the thickness of the drip line and the intervals between the radiators, which are usually installed every 8-24 inches (20-60 cm). The appropriate distance between them is determined by the moisture retention capacity of the soil.

With subsurface drip irrigation, the soil surface itself remains dry, which means that neither solar heat nor wind will lead to moisture loss. An SDI system that is properly installed, maintained and managed will be the most efficient irrigation system currently available.
