A legume crop is typically grown to help restore the nitrogen levels.

Soil fertility is the ability of soil to produce crops. Soil productivity is the soils ability to yield a certain amount of crops.
The difference between soil fertility and soil productivity is that soil fertility involves the soils and fertilizing them per the types of plants, crops, and soils, being used. The soil productivity has to do with the drainage of the soils, the amounts and types of fertilizers, and the progress of the plants and crops due to fertilization.
Mixed crops means different vegetables and cereal crops.
Cereal crops are herbs belonging to family Poaceae.
cereal root crops ligumes industrial crops fiber crops oil crops pasture and silage
Because the majority of crops (cereal crops) are wind pollinated.

The growing of different kinds of crops on a piece of land in a preplanned succession is known as crop rotation. In the rotation of crops, leguminous crops like pulses, beans, peas, groundnut and Bengal gram are sown in-between the seasons of cereal crops like wheat, maize and pearl millet. The leguminous plants are grown alternately with non-leguminous plants to restore the fertility of the soil. When the cereal crops like rice, wheat, maize are grown in the soil, it uses up a lot of nitrogenous salts from the soil. If another crop of cereal is grown in the same soil, the soil becomes nitrogen deficient. So by rotation a leguminous crop is grown. There plants have the ability to fix atmospheric nitrogen to form nitrogen compounds through the help of certain bacteria present in their root. These nitrogen compounds go into the soil and make it more fertile. After the leguminous plants utilize some of the nitrogen compounds, the rest of it is left in the soil to enrich it. Thus, planting a leguminous plant will result in nitrogen rich soil and when a cereal is grown in this soil there is increase in food grain production.
The carbon content of major cereal crops is forty percent. This is applicable to dry content of the cereals. Carbon happens to be the biggest content.
Soil fertility is if it has enough nutrients and water to support crops.
Non-cereal crops generally means it is not a grass or grain. Tis includes fruits, vegetables, and select nuts as well as select grasses at cannot be eaten by humans.
Because it increases the fertility of soil.
