SOIL PRESERVATION THROUGH THE PERFECTIONING OF ITS BASIC WORKS

Abstract

The classic technology of soil work for sowing presents many advantages, but also important drawbacks, regarding the destruction of the soil structure, the excessive subsidence, erosion etc., but also of big power consumption (the ploughing includes 30...35% from the total energetic consumptions in agriculture). The new technologies of sowing in un-plough lands or partial prepared, remove these disadvantages, but require the strict achievement of agro technical rules, for which the Romanian agriculture isn't prepared to accept them. Also, the optimization of the deep soil loosening work influence positive as much his features, and the economic results obtained to his cultivation. These aspects are analyzed in the paper on the strength of some authors' researches.
