Influence of various types of fertilizers and equipment on the physical and microbiological properties of soil

Abstract

© 2020 IOP Publishing Ltd. All rights reserved. The cultivation of corn hybrids on silage, corresponding to the terms of ripeness of the district, and their timely harvesting allow to harvest silage containing 6.09-6.29 MJ per 1 kg of feed. High-quality silage should contain about 30 % SV, more than 10.8 MJ of exchange energy per 1 kg SV, at least 32% starch, no more than 4.5% crude ash, about 20% crude fiber and have a coefficient of digestibility of organic mass of at least 75 %. Therefore, it became necessary to improve the technology of its cultivation in the fields of crop rotations in order to increase the concentration of metabolic energy in the feed. It should be noted that an important role in the technology of growing corn should be assigned to the variety, fertilizers, biological products, growth stimulants and biological fungicides.
