The existing system of agriculture in the Republic of Moldova has led to decreasing the humus content, destructuring ofarable soil layer and loss of its resistance to compaction. Remediation of degraded chernozem characteristics can beachieved by phytoameliorative methods requiring cultivation of grasses and legumes with fasciculate root system. Given the fact that in the Republic of Moldova is excluded remediation of soil quality status by the method outlined (0.4ha of arable land per capita) were developed and tested methods for remediation of soil characteristics without interrupting the agricultural production process. As a result of cultivation the mixture of perennial legumes and grasses herbs, the crop which was used as fodder production, it was established that this mixture of herbs over a period of 4-6 years had a positive influence on the quality state of degraded arable layer of chernozems: increased organic matter content, improved structural condition, began forming a fallow layer of 4-5 cm. Restoring characteristics of arablelayer of chernozems by tested technology can be achieved in a period of 15 - 20 years. Implementation of this method toremedy the quality state of chernozems is only possible when restoring the livestock sector and allocation underperennial grasses at least 15 percent of agricultural land.
