AGRICULTURE IN THE REPUBLIC OF MOLDOVA IN TERMS OF SOIL REMEDIATION AND PROTECTION

Abstract

The purpose of our research presented in this article is to remedy soil properties through phytotechnical methods by creating a positive balance of carbon, nitrogen, humus and stopping arable degradation processes. The existing system of agriculture in the republic led to the dehumification, destruction, biological degradation of the arable layer and loss of the material's resistance to compacting. The researchers are carried out in the Central and Southern areas of the Republic of Moldova. A phytotechnical process was applied from a mixture of leguminous and grassy perennial herbs in equal proportions (alfalfa + steppe raspberries + vetches), the harvest of which was used as fodder production. As a result, a positive influence on the quality of the degraded arable layer of chernozems was established. Thus, they were returned to the 0-35 cm layer of arable soil of about 25.5 t/ha of absolutely dry organic residues (5.1 t/ha annually with an average nitrogen content of 1.9%)and the synthesis of about 5.5 t/ha of humus (1.1 t/ha annually) was created, the content of organic substance in this layer increased on average by about 0.20% or 0.04% annual.
