The state of soil fertility from Republic of Moldova in the intensification of degradation processes has been presented. Arable soil humus state is the worst in the last 30-35 years. The annual loss of humus from agricultural land cleared from above the level of mineralization of 700 kg/ha and the total deficit, given the erosion losses consists 1100 kg/year. The current state of actual soil fertility is unsatisfactory on the 90% of the land, and about 10% of agricultural land - is critical. Current balance of nutrients in soils is profoundly negative caused by non-application of fertilizers. Developed programs for increasing soil fertility provide scientifically substantiated measures for their implementation on agropedoclimatic zones.
Abstract. The studies carried out and the results obtained on the humus state of meadow brown soils are fully consistent with the literature. The change in the humus content in the soils of the meadow soil formation process depends on the effect of surface and ground moisture on humus formation. Studies have revealed that the humus content in meadow brown soils decreases gradually and relatively evenly with depth. For meadow soils with a meadow process of soil formation, there is a general tendency for a decrease in humus from the upper horizons to the lower ones.
