Figure 6. Area of land planted with mulch, to be covered with shrink tunnel RESULTS AND DISCUSSIONS The impact of mechanization on the environment and the soil should be highlighted by the fact that any agricultural aggregate is part of a context which does not only refer to the technique or technology is adopted but also functional issues related to technology and to the choice of the best periods for carrying out agricultural works. These two factors are of great importance both for the purposes of reducing the cost and over the land. Climate change in the South-western part of compaction and not only the physical characteristics and chemical modification of land leading to the realization of a concept in the case of processing land especially the sand from this area. The use of agronomic practices and soil management systems and environmental protection are responsible for the main effects on a specific type of farming area and can be valid and timely solutions to achieve high yields by using effective natural resources and manpower in the area. This type of agriculture must transform as little soil and organic substance composition, fertility, structure and natural biodiversity to avoid such degradation, erosion of any kind but also compact.

Influence of time charge of wheels about on izostatics curves repartition in case of a constant require on wheel Agriculture includes such techniques as: no tillage, direct sowing or minimum tillage reduced processing. Also, the use of protected crops, especially with foil mulches or establishing protective curtains from cultures with high waist (rye) or curtains. CONCLUSIONS - Reduction of traffic on the ground; - Traffic Control area cultivated by use of plant life; - Reducing the number of works by applying non-till system; - Using light equipment; - Agricultural equipment with wheels in tandem; - Practicing crop rotations that include plants with deep roots and penetrating power.
