Over a period of more than 140 years, the humus content in the arable layer of the chernozems, as a result of their use in agriculture, decreased by 2.47% or 43.2% from the content of the virgin (natural) chernozem, the rate of humus reduction of was 0.019% annually. Maintaining the annual reduction rate of humus content presents a significant ecological and economic danger for Republic of Moldova. The state quality of the investigated chernozems regarding the content of organic matter is satisfactory. The factors limiting the productivity of chernozems (and other soils) are: low humus and nutrient content, strong compaction and destruction of the arable and post-arable layer. The quality of the chernozem (and the soil resources in general) must be maintained by administering the organic-mineral fertilizers at optimum doses, incorporating plant residues and secondary production in soils, respecting crop rotation with the introduction of alfalfa into the soil, increasing the proportion of leguminous crops up to 20-25%. Key words: agriculture, chernozem, degradation, fertilizer, humus. Introduction At present, everyone has a firm opinion about The content of organic matter in soils is a decrease in the content of humus in soils. Indeed, the genetic and classification feature characteristic of loss of humus from arable soils is possible for each known types of soils. The change in the content various reasons (7): of humus in soils occurs extremely slowly, being the - Increased mineralization of organic matter result not of temporary circumstances, but of a due to intensive machining, liming, predominant use complex and lengthy previous history of the soil- of mineral fertilizers, consumption of organic matter forming process and the interaction of the soil with in crop formation, which does not allow to the environment. compensate for the natural decrease in humus; For each soil type, a certain stable humus - Inadequate intake of organic residues due to content in the upper soil horizons and a stable type low yields and lack of organic fertilizers. In a of distribution of its reserves along the profile have normally formed farming system, more than 50% of been established. At the same time, each type of soil plant nutrients should be returned to the soil as part is characterized by a certain qualitative composition of organic matter (litter, stubble, root residues, of humus (4). organic fertilizers, etc.). The humus content in the soil of each pedo- - Loss of humus during erosion and deflation. climatic region is a certain constant value, it varies These losses will be even more significant from soils within a certain limit and the increase in its amount of light particle size distribution. “Not only that, and is associated with a long cultivation period with the the humus that fell into the sandy soil has relatively use of sufficiently high doses of organic fertilizers, few chances to remain there; firstly, there is nothing the expansion of leguminous crops, and the to connect humus with, secondly, due to the porosity reduction in the area of clean fallow.
