A direct method of applying a crop rotation, in which agricultural crops and fallows on fields are arranged in diagonal pattern downwards, and the crop rotation is carried out. The agricultural crops and fallows on the fields are arranged in diagonal pattern from the left downwards to the right and in the same manner, in diagonal pattern from the left downwards to the right, said crop rotation is carried out, that is by the principle "frontwards". In doing so a period of the first rotation cycle, that is full duration of applying the fields of the crop rotation, is lesser than double number thereof for one unit, for example for a seven-field crop rotation a full duration of applying is 13 years. |
