Crop rotation is a technique used by farmers to sustain the health of soil. Certain plants are more taxing on the soil so it is necessary to rotate which ones are planted.
crop rotations give the soil a break from having to support the same crop which drains the soil of the nutrients. Eventually the slil is deprived of the nutrient and the plant will no longer grow there.
Middle Eastern farmers were the inventors of crop rotations. They were known to practice crop rotation as early as 6000 BC.

Crop rotations increase crop yields by improving soil conditions and reducing weed and insect populations. Rotations also help producers use conservation tillage successfully. A well- planned crop-rotation system can help producers avoid many of the problems associated with conservation tillage, such as increased soil compaction, perennial weeds, plant diseases, and slow early season growth.

Soybeans are an example of increased Southern farming variety beginning in the 1970s.
Crop rotation can disrupt insect life cycles and enrich the soil with additional nutrients. Crop rotations increase soil fertility, protect the environment, eradicate weeds, illnesses, and pests, and increase the variety of crops and markets.
Rotations is a noun (plural form of rotation).

A circle represents one complete rotation, which corresponds to an angle of 360 degrees or (2\pi) radians. Since rotations can be measured in multiples, there are infinitely many rotations in a circle, including both full rotations (360 degrees) and fractional rotations (e.g., half a rotation at 180 degrees).
Positive rotations typically go counterclockwise.
