Investigations on soil conservation and precision of tillage with tractor and gantry units

Abstract

The compressed soils can beloosened more intensively with the use of the rotary cultivators. It is suggested to separate stones and clods in the stony soils and the bigger stones should be removed from the growing zone of potatoes. The horizontal cultivators are more universal, they can be used to loosen and to mulch the sod. It is purposeful to use the technology of the harrowing and the multiple hilling. Thus, the space between rows is compacted by the wheels of the tractors. The number of passes is minimized during the potato growing. The new generation of the tractors with front and rear linking systems makes more perfect combined aggregates, when some of them are mounted on the front of the tractor and others on the rear of the tractor. Gantry agriculture has great influence on the soil structure. It enables to investigate theoretically possibilities of minimization of the interaction between the chasis and the soil compacting by different types of circular and shuttle gantry modules. It is possible to investigate the influence of the uneven fields on curvature of chassis paths and to select the chassis types.
