Each crop uses a different combination of nutrients from the soil. Planting the same crop over and over uses up those nutrients so the crop will have less yield each year. Alternating crops allows the nutrients used by one crop to be replaced by a different crop.

What is the system for crop rotation?

It is when one species of crop is rotated with a different species of crop every year. For instance, a field that was planted with canola one year is planted with wheat another year. That same field may be sown into hay for a few years before being turned back to crop. This is so that the nutrients in the soil are not "mined" out of the soil to the point where crops cannot be grown anymore. Different crops have different nutrient needs than others. For instance, legume/oilseed crops like canola and peas fix nitrogen and put nitrogen back into the soil, whereas cereal crops like wheat or corn use it up.

What is the relationship between mono cropping and mixed cropping?

Mixed croppingis growing of two or more crops simultaneously on the same piece of land.It is also known as multiple cropping. This type of cropping leads to an improvement in the fertility of the soil and hence, increase in crop yield because when the two crops are properly chosen the products and refuse from one crop plant help in the growth of the other crop plant and vice-versa.Mixed cropping is an insurance against crop failure due to abnormal weather conditions.Some successful mixed cropping practices are:1.Soya Bean+ Pigeon pea2.Maize +uraddal (Black gram)3.Pigeon pea + Mung dal (Green gram)4.Groundnut + Sunflower5.Sorghum + Pigeon pea6.Wheat + Chickpea7.Barley + Chickpea8.Wheat + Mustard9.Cotton + Groundnut< While, >The growing of different kinds of crops on a piece of land in a pre planned succession is known ascrop 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.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.Rotation of crops help in weed control and pest control.Some successful crop rotation practices are:Maize + mustard , Rice + wheat etc
