A well-designed crop rotation, e.g. inclusion of legume crops, can improve soil structure and fertility, optimise nutrient and water use, and reduce the occurrence of disease, pests and weeds. Interventions, such as the use of nitrogen fertilisers and pesticides, can thus be minimised. On cash crop farms, however, including fodder legumes in crop rotation does not generate income.

With Farm/IT, the positive effects of rotations in terms of investment in soil fertility can be shown to have tangible economic benefits. Farm/IT can also optimise crop rotations to achieve multiple objectives, for instance, improving crop yield while reducing fertiliser application.
