Efficiency of Combed Straw Harvesting Technology Involving Straw Decomposition in the Soil

This article deals with the problem of harvesting combed straw by mixing it soil and process decomposition in particular. The idea purpose research are also analysed terms circular economy, which represents a closed cycle. Combed is seen as by-product reused fertilizer to increase fertility, thus reducing negative impact on environment increasing efficiency organic matter use. To analyse qualitative aspect process, introduction an indicator proposed—the coefficient. Experimental studies were carried out using mathematical theory experimental design, where response function represented functional dependence coefficient length its cutting nitrogen phosphorus application doses. For studies, Box–Behnken design was used, made possible calculate regression coefficients known formulas. Verification obtained according Student’s t-test showed that all them significant. According Fisher’s test, established model adequate can be used for further research. As determined study, shredded incorporation improves properties increases biological activity. Ultimately, this plant nutrition crop yields. experiment results reduced amounts fertilizers applied, leading reduction direct production costs growing cereals following year. integration several technological processes, such cutting, shredding, incorporating into simultaneous fertilizers, economic grain shortens payback period investment.
