Functional capabilities of the experimental unit for introducing into the soil aqueous solutions of fertilizers

One of the ways to revive and preserve meadows and pastures in the mountainous zone is the in-troduction of liquid fertilizers to the sparse phytocenosis and exposed areas that have lost valuable forage species. To solve this problem, for the first time a new method for improving mountain meadows and pastures was proposed by the staff of SKNIIGPSKh, for the implementation of which, for the first time, a prototype of an aggregate that performs the application of liquid fertilizers to the soil of the planted area was created on the basis of the KGG-2,4 mining cultivator. According to calculations on the experimental sample of the unit, a tank of 240 liters is installed, which ensures continuous operation of the unit within one hour. The prototype of the unit, due to maneuverability, mobility and light weight, is quite suitable for working on sloping lands in farms for superficial improvement of mountain meadows and pastures with a slope up to 16°. This method opens the possibility of performing sowing operations even in the dry period, making the grass stand thicker, which prevents water and wind erosion. The unit was tested on the basis of the experimental workshop of the mechanization group of SKNIIGPSKh and on the experimental plot in the village of Dargavs of the Prigorodny district of the Republic of North Ossetia-Alania on a total area of 300 m2 in triplicate. The aim of the research was to develop a prototype block module of a multifunctional aggregate for applying liquid fertilizers to the soil on mountain meadows and pastures, which provides an increase in the productivity of agricultural landscapes and the profitability of agricultural production by 15-20 %. The novelty of the unit is that for the first time a prototype of a block-module of a multifunctional unit based on a mountain chisel cultivator KChG-2,4 (designed by SKNIIGPSKh) equipped with working elements for introducing liquid mineral fertilizers and solutions of other preparations onto the slopes of meadows and pastures with Rocky protrusions on the surface, providing an increase in the productivity of agricultural land, reducing erosion processes and increasing the stability of agrolandscapes.
