Environmental assessment opportunities technology implementation No-till at the GС “Hrozynske”

Abstract

No-till is a brand-new production system. Implementation of this technology carries out in economy of area of radioactive pollution Governmental Company “Grozynske” by researching indices of the density of soils and reserves of soil moist.In the period of seeding of winter wheat, we found a clear dependence of density of soil on the system of processing it. After traditional technology of processing the seeding layer of density of soil was in limits of 1,06–1,10 g/cm3. At no mechanical processing of soil, the average value of this index totaled 1,20 g/cm3 with insignificant variety, which significantly exceeds this index comparing with the variant of traditional technology.However, the increase of density had no negative impact onto well-timed appearance of young plants. This certifies on efficient level of aeration and that such density of the soil of seeding layer does not create a mechanical obstacle for wheat plants.Natural factors of autumn-winter period always affect agrarian and physical indices of fertility of the soil. The indices of density of soil and reserves of available moist in the period of spring tillering of wheat certify on the following: preserved regularity of increase of density index with a depth at traditional technology of processing soil and its decrease – to zero.Analyzing the density of arable layer of soil and reserves of moist in the period of harvesting winter wheat, we can highlight the fact that the index of density tends to lowering, and the index of available moist – to the increase.The conclusion is that if permanently leave residues of plants on the surface of plants and avoid mechanical processing, the physical condition of top layers of soil shall improve. At traditional technology such regularity is not distinguished.
