Abstract
Soybean Productivity in Rice Crop Rotation Depending on the Impact of Biodestructor on Post-Harvest Rice Residues
Highlights
Stubble, straw, stalks and other plant residues, which are crushed and buried in the soil, are a source of organic matter and act as an environmentally safe factor that can increase soil fertility
The content of pathogenic microflora under this condition was 21.8% lower compared to the control (30 kg/ha carbamide), and the number of saprotrophs increased 3.3-fold
Fungi are an important constituent of soil fauna and their biomass is usually greater than the biomass of bacteria (Gaddeyya et al, 2012; Nosratabadi et al, 2017)
Summary
Straw, stalks and other plant residues, which are crushed and buried in the soil, are a source of organic matter and act as an environmentally safe factor that can increase soil fertility. Post-harvest residues help reduce soil density, improve water permeability and microbiological activity of soils. Their decomposition is accompanied by an increase in the number and activity of soil microflora. Phytopathogenic fungi and bacteria retained on plant residues are capable of penetrating plant cells and tissues, which can lead to infections and significantly reduce crop yields (Ampt et al, 2019) These negative phenomena can be prevented by using biodestructors, which accelerate the decomposition of plant residues, transform them into organic matter, improve soil fertility and provide a steady increase in crop yields (Marinoha, 2010; Bolokhovsky, 2013; Korsun et al, 2017). It was shown that only about 20–25% of wheat straw decomposes in six months, and about 50% in 18 months (Kushnaryov et al, 2012)
