Working body for pre-sowing application of liquid mineral fertilizers in the soil

Abstract

To obtain high yields of crops it is necessary to create the most favorable conditions for growth and development of plants and in particular their root system, it is necessary to create optimal parameters of the subsoil layer of soil, where the root system of plants develops, normal growth and aboveground mass. Deep and strong root system reduces the dependence of plant development on weather conditions, which is very important in areas of risky agriculture. Soil compaction has a detrimental effect on plants, limits their productivity, reduces pores between soil particles containing air and water, and causes its compaction external pressure by tractors and cultivators destroys pores, roots can not properly grow in such soil, and plants do not get the right amount of nutrients needed for their maximum growth. Numerical studies have shown that excessive looseness and density under the seed layer, as a rule, limits the penetration of plants into the soil. Their surface development is highly undesirable because it leads to a deterioration in the supply of plants with moisture and nutrients and adversely affects plant productivity. When liquid fertilizers (ammonia water, CAS) are applied to the dense layers of the soil at the rate of 0-40 kg of active substance on nitrogen, the growth of the root system deep into the soil is significantly enhanced. Existing working bodies for the application of liquid mineral fertilizers to the soil cannot perform this task at the appropriate level. Under the influence of known flat wedges there is a deformation of the soil, which always exceeds the allowable limits for the subseed layer. The working body with only the minimum cutting angles and blade width can satisfy the proposed requirements for deep application of liquid fertilizers without a significant reduction in the density of soil composition before sowing.
