The existing system of agriculture in the Republic of Moldova led to humus losses, compaction of arable layer and decrease of its resistance to degradation factors. Researches established that only radical corrective factor to cardinal remediate the degraded characteristics of chernozems is that which leading to the formation of this type of soil - steppe vegetation composed by grasses and legumes herbs with fasciculate root system. The chernozems with whole profile, being grassed 15 years in a system without utilization of vegetal aerial mass, recovered 70 percent of humus content in the profile and restore the initial soil typical characteristics. Lucerne with its pivoting root system contributed poorly to remediation the structure and increasing the content of organic matter in soils. Resulting from the fact that in the Moldova is excluded the possibility to cardinal remediation the soil quality status by grassed (0.4 hectares of arable land per capita) has decided to develop and test phytotechnical methods to remedy the soil characteristics without interrupting the production process from agriculture.
