In land management, it is necessary to provide for the long side of the fields to be in the direction of the horizontals for areas endangered by water erosion and across the prevailing winds for areas endangered by wind erosion.
Anti-erosion crop rotations include a larger number of crops with fused surface (wheat, barley, rye, triticale oats, rapeseed, etc.), as well as perennial grasses and mixtures thereof. When trench crops are included, the crop rotation fields must be narrower and arranged in the form of belts in the horizontal direction. In this way, belts of trench crops alternate on the slope with belts of crops with a merged surface in order to cross the water outflow.
The sowing of grass belts between the separate fields of the crop rotation of perennial species parallel to the horizontals of the block significantly reduces the water erosion.
Preferably winter crops, as well as cover crops and green manure crops between the main crops, should be included in the crop rotation. As a result, the fields are in a state of black fallow for a shorter period of time.
