Abstract

The paper presents experimental data on the change in the winter wheat yield when using straw, green manure, and a biological preparation as a fertilizer in one field experiment and using different doses of zeolite and its modifications in another. It has been ascertained that organic and organo-mineral fertilization systems have a positive effect on the winter wheat grain yield. The application of straw, green manure, and a biological preparation in the technology of winter wheat cultivation made it possible to increase the yield of winter wheat by 7-13%. It is quite difficult to ensure the volume of the produce obtained at the level of mineral fertilizers using only the system of organic fertilizers. The latter is possible when applying a new generation of fertilizers based on high-silicon rocks in the technology of cultivating agricultural crops, which are natural environmentally friendly materials. The grain yield increased in the latter case by 7-56%.
