Özet
Plants require a relatively mechanically weak, open soil condition, conducive to easy and extensive root development, good aeration and water supply, when subsurface drainage is satisfactory. Conversely, much more compact conditions are desirable for good traction and the support of wheels and tracks. There are three primary ways of reducing the overall compaction of field soils by agricultural vehicles: (1) Reduction of the number of passes of conventional machinery, (2) Reduction of the vehicle mass and the contact pressure of wheel systems. (3) Confinement of the traffic to permanent or temporary wheel tracks (controlled traffic). The objectives of this study are: to define the optimum soil compaction, to explain the effects of excessive soil compaction on plant growth and soil physical conditions; to examine the methods of preventing and reducing of excessive soil compaction hazards; to present the the application of wide span tractor.
