Q. fertility? like, planting corn in one area and soybeans the next? or moving the corn crops to a new field and letting the barren field rejuvenate

A. It's called crop rotation. Crops like cotton and corn use a lot of nutrients like Nitrogen. Rotating with legume crops such as soybeans will build back the soil. Also weed control is improved when you are rotating a grass crop such as corn with a broad leaf crop like soybeans. Crop rotation is a technique used by farmers for many years. Leaving the fields barren, or fallow as it is called, is used mostly when it is necessary to conserve moisture. Use if irrigation has replaced a lot of fallowing of fields.
