Abstract:
The basic components of chernozems conservative tillage technology between Prut and Dniester are stipulated in the
State Program “Conservative tillage system of soils” developed by Ministry of Agriculture and Food Industry of
Moldova. Development and implementation was conditioned by accelerated degradation of soil resources in the region.
Conceptual framework theoretical and applied in the regional conservative tillage system of chernozems (RCTSC) is
provided by procedural approach of soil fertility in the concept of landscape evolution of chernozems genesis.
Chernozems genesis is perceived as result of landscape development determined by complexation and intensification of
soil-plant relationship. In accordance with these basic components of RCTSC the most important are landscape
adaptation of agroecosystem, biologization and their ecological restoration focused on restoring composition and
volume of substances through biogeochemical cycle’s renaturation in the elementary pedogentic processes in the
formation of chenozems type. A component part of RCTSC is practice of integrated system for plant protection in a
crop rotation with minimum 5 crops including one ameliorative. RCTSC implementation involves elaboration of a
technology fiche that provides a transitional period lasting 3-5 years during which are practiced biologization and
optimization processes for agrogen layer
