Monitoring and recovery of the soil biota in conditions of the degradation processes intensification in the Republic of Moldova

Abstract

Statistical parameters, criteria and scales of the soil biota stability to the natural and anthropogenic impact in the Republic of Moldova has been developed. The modifications of the biological properties of soils as a result of their long-term arable use and the impacts of erosion processes have been established. The zones of homeostasis (natural stability) of the biota of different soils have been determined for the first time at the national level. The current status of biota of arable soils is characterized by the significant reduction in comparison with soil's standards that are in conditions of natural ecosystems and with the level of the 1960s. The scales of soil biological indicators for the evaluation of the degree of chernozems' degradation and its environmental certifications have been developed. The application of no-tillage technology on the soils of the Republic of Moldova has been discussed.
