NEW MECHANIZATION TECHNOLOGY FOR DECOMPACT AND AERATION IN-DEPTH OF IMPROPER SOILS, WHILE GIVING OF NUTRIENTS

Abstract

New mechanization technology of soil working in arable substrate aims decompacting and aeration in depth of poor soils together with the administration of nutrients that can be applied on about 19.8% of total agricultural area of our country. Applying them to an appropriate quality level corresponding to agopedological requirements at as low cost and low power consumption required to promote a new technical equipment, with higher constructive and functional parameters, for wheeled tractors of 180-240 hp, equipped with five active organs such as reversible chisel knife and two rollers with claws, which is mounted an equipment to manage difficult soluble nutrients. New machinery called DECOM-FERTI, achieved a maximum depth of 40cm from the chiselation of ground and max. 60 cm at the working of soil from the arable substrate, working width being about 2.5 m and the working capacity of about 1.56 ha/h; administered nutrients with rates between 50 ...250 kg/ha.
