Refacerea fertilităţii solurilor arabile erodate prin utilizarea gunoiului de grajd

Abstract

In the Republic of Moldova, a country possessing an agrarian oriented economy, multiple social problems can be solved though the protection and amelioration of the soil, which is the main means of agricultural production. The protection of soil fertility is thus a social primordial problem. The quality of soil crust on the majority of agricultural lands is un satisfactory. Erosion affected and humus lacking surfaces continue to extend. Currently, the total surface of soils subjected to erosion processes is of 864,631 ha or 25.5 % out of the total surface of 3,384,626 ha. The recovery of eroded arable soil productivity is possible through the rational use of organic fertilizers on a well - set anti-erosion foundation. The incorporation of manure of different origins into the soil brings about an available energetic contribution: increases the heterogeneity, decreases and uniforms the entropy, influences positively the humus accumulation processes and increases soil quality and fertility, including crop productivity.
