It also defines cropping system and its objectives to efficiently utilize resources while maintaining stability and higher returns. Cropping systems are classified as monoculture, intensive cropping, sequential cropping, and crop rotation depending on available resources and technology.

Crop rotation plants different crops in sequence to improve soil health.
