Ilyin Department of Economics, Director of FSFRI, Verkhnevolzhsky FASC, Moscow, Russia Journal Article 2023 09 30 Intensive use of arable land with unbalanced application of mineral fertilizers negatively affects soil fertility and the environment. Anthropogenic activity alters the relatively stable natural balance. The nature and direction of such alterations are largely determined by the intensity of agricultural practices implemented during field crop growing, among which the most important are the cultivation method, the fertilizer system and chemical soil reclamation. To improve the balance of organic matter in sod-podzolic light loamy soil, it is recommended to apply organic mineral fertilizers with a chemical ameliorant (lime), which reduces the rate of humus mineralization in soil and improves plant nutrition. The article shows the influence of mineral fertilizers, manure and lime on humus balance and its stabilization in the agroecosystem of the long-term field experiment. https://cjes.guilan.ac.ir/article_7124_0446feec1cea17fb3aff6c7f468b8216.pdf
