Abstract
Aim. To identify the effect of biological preparations applied with or without nitrogen fertilizers for crop by-product, their incorporation into the soil on the decomposition of plant residues and composition of mobile humus substances in typical slightly eroded chernozem.Materials and Methods. The study was carried out in the field experimental station of Kursk FARC in the cycles of cereal and cereal-row crop rotations in variants with by-product treated with biopreparations; with applied biopreparations + nitrogen fertilizers; with applied nitrogen fertilizers and without biopreparations. To study decomposition the content of unhumified organic matter was determined in the topsoil by the monolith method after by-product incorporation into the soil and 3045 days after their decomposition. Simultaneously the composition of mobile humus substances in the soil was determined.Results. The decomposition of crop by-product and after harvesting and root residues mixed with it in the soil and treated with biopreparations or nitrogen mineral fertilizers was studied for the first time. The peculiarities of the effect of the factors studied on the degree of plant residue decomposition and the composition of mobile humus substances were shown.Conclusion. It was determined that treating the by-product of barley, buckwheat and sunflower with bioproducts, both with applied nitrogen fertilizers and without them, contributed to the increase in the degree of plant residue decomposition as compared with the control and nitrogen mineral fertilizer application. In the years which are favourable according to hydrothermal conditions the improved quality of mobile humus substances of the soil influenced by biopreparations are noted and under extreme conditions the tendency to the improvement of their quality is observed.

Влияние биопрепаратов на разложение растительных остатков сельскохозяйственных культур в черноземе типичном // Юг России: экология, развитие. Выявить влияние биопрепаратов на разложение растительных остатков сельскохозяйственных культур и состав подвижных гумусовых веществ в черноземе типичном слабоэродированном. Одновременно был определен общепринятым методом состав подвижных гумусовых веществ в почве. Впервые изучено разложение обработанной биопрепаратами или азотными минеральными удобрениями побочной продукции и смешанных с ней в почве пожнивно‐корневых остатков. Показаны особенности влияния изучаемых факторов на степень разложения растительных остатков и состав подвижных гумусовых веществ в почве. Что обработка побочной продукции ячменя, гречихи, подсолнечника биопрепаратами, как с азотными удобрениями, так и без них, способствовала увеличению степени разложения растительных остатков по сравнению с контролем и внесением минеральных азотных удобрений. Ключевые слова Растительные остатки, биопрепараты, разложение, типичный слабоэродированный, сельскохозяйственные качество подвижных гумусовых веществ
