CROPPING SYSTEMS
This unit treats the distribution of crops in time, i.e. whether shifting cultivation, continuous cropping, monoculture, or crop rotation and the distribution of the crops in space on the field, (i.e. whether intercropping or sole cropping) as well as the level of management and resources utilized to produce the crop, (i.e. whether production is intensive or extensive) and the type of crops grown, (i.e. whether orchard, arable cropping, pasturing, or forestry). The advantages and disadvantages of each cropping systems and the principles of the rotations were also discussed.
