Planting different types of crop on the same land at different times of the year. Causes less drain on the soil.
Because farming certain plants drains certain nutrients from the soil. Rotational farming rotates the crops being grown (sometimes fields are left fallow i.e. empty) and therefore, nutrients remain in the soil.
In intensive rotational grazing, no. In dairy farming (which is intensive), yes.
