Crop rotation

Crop rotation is the practice of moving different crops on the same land. If this process was not done, harmful organisms and other pests would spread when the crop is prepared for raising. Crop rotation also helps reduce the loss of water and soil nutrients.

A normal way to adopt crop rotation is to mix green manure and other organic matter in with the soil. This adds nitrogen and other nutrients that plants need to grow.

Cycling crops can also help aeration when plants with deep roots are changed with plants that have shallow roots.

It was used in New Zealand during the 1920's and onwards, as an efficient way of farming.
