The use of complex organic fertilizers in the cultivation of grain crops

In order to determine the effectiveness of the use of soils, laboratory studies were carried out in a mixture with various local agricultural ores, meliorants and waste from agricultural and industrial production, including microorganisms, macro- and microelements. The work was carried out as part of the implementation of a comprehensive project to create high-tech production, provided for by the Decree of the Government of the Russian Federation No. 218 dated April 9, 2010 on the topic "High-tech production of soils by innovative waste processing methods" (state contract identifier 000000S407521QL90002). In the introduction, the requirements for soils on the content of harmful substances are given. The research methodology contains objects, schemes of experiments, the place and conditions of their conduct. The results provide a detailed analysis of laboratory studies conducted with spring wheat and barley, with the reduction of biomorphometric indicators. The illustrations show the growth and development of the vegetative mass of plants. The conclusions reflect the results of the data obtained. The analysis of the average indicators of the two studied crops allowed us to identify 9 options for the subsequent selection of optimal components and ratios: Soil 75%+25 KOU%+defecate, Soil 75%+25 KOU%+phosphogypsum, Soil 75%+25 KOU%, Soil 50%+50 KOU%+phosphogypsum, Soil 50%+50 KOU %+zeolite, Soil 75%+25 KOU%+zeolite, Soil 75%+25 KOU%+ NPK, Soil 50%+50 KOU%+ NPK, Soil 50%+50 KOU%+defecate.
