In recent decades the quality status of Moldova's soils was worsened. The soils are physically, chemically and biologically degraded. The average values of the soil organic matter losses made up 0.5 t/ha per year. Currently the humus content in soils amounted 3%. In the case of chernozem the humus value of 3% is considered as critical threshold. Below this value the chernozems not have self-regulation and return capacities to equilibrated state. Thus, less than 3% of humus the chernozems have stable trends of degradation. Soil quality assessment involves measurement of soil properties which serve as sensitive indicators of soil functions change resulting from the use and management of soil resources. Indicators of pressure, state and impact is helpful in evaluating the quality of soils. Knowing the status of soil quality requires development of adequate agricultural policy, implementing the measures to combat soil degradation and technologies to improve their fertility.
