Ecological Efficiency of the Implementation Technology of the Mini-Till and No-Till Soil Tillage in the Republic of Moldova

摘要

Agriculture currently practiced in the country faces a number of major problems that seriously affect rural development. The classic system of soil works has led to a gradual increase in production, but it has also resulted in the phenomena of degradation of the features, the decrease of the production capacity of the agricultural lands. The article describes the polygon that was organized in Central Moldova to study the processes of remediation of the quality of common chernozems under the influence of green fertilizers with the implementation of the Mini-Till and No-Till systems. As a result of the researches carried out a balanced or positive balance of the organic substance and the nitrogen in the soil is ensured each year, they return to the arable layer with vines harvesting intermediate crop, used as green fertilizer about 8 t/ha dry matter of airborne organic mass and roots with a nitrogen-weighted average content of about 3.4%; the synthesis of 2.0 t/ha of humus is ensured. Ecological efficacy provides prerequisites for the implementation of the Mini-Till and No-Till soil cultivation systems, which, combined with this technology, will contribute to the remediation of soil properties. The technology is recommended to be implemented in advance on about 50 thousand ha of arable land.
