This measure consists of the promotion of rotations of dry grassland crops, which include leguminous species and oilseeds, substituting cereal monoculture. Introducing leguminous species in rotations implies improved levels of nitrogen in the soil, improving its structure and fertility, which makes subsequent crops require less input nitrogen fertilizer. Therefore, the cultivation of legumes has a positive effect on the mitigation of climate change, leading to a decrease in emissions associated with the use and production of such fertilizers. In addition, from the point of adaptation to climate change, the resilience of soil and crops is increased, making it an adequate measure of adaptation, especially in rainfed and irrigated arable crops. Finally, it can also reduce the pressure from pests, diseases and weeds, as crop rotation breaks the cycles of these.
