Strip Cropping, Wind is a practice of alternating strips of crops that are planted perpendicular to the prevailing wind to reduce soil from blowing away. In many cases the same crop may be being grown. But in one strip the stubble from the last crop is left untilled. The area is left (fallow: not planted, not tilled accept for weed control) for one year. Each strip could though have either a spring or fall seeded crop, a row crop or a close grown or drilled crop. One of the crops might be a legumes that stays for several years.
The purpose of such a practice is to prevent all of a given field from being tilled at one time. The area not being tilled traps wind blown soil.
