This practice helps enhance soil fertility, control pests and diseases, and maintain the overall health of the soil. Monoculture refers to the cultivation of a single type of crop on a given piece of land. Polyculture involves growing multiple crops simultaneously on the same piece of land. Intercropping is a method of growing two or more crops together in close proximity.
