Strip farming is a term used to describe a form of agriculture where farms are separated by strips of grass or other vegetation. This method is often used on hilly terrain to prevent soil erosion and improve water quality. There are several synonyms for strip farming that describe the same cultivation technique, including terracing, contour plowing, and ridge-tillage. Terracing involves building walls of soil in a series of level steps on steep slopes to provide a level space for farming. Contour plowing, on the other hand, involves plowing across a slope, rather than up and down, to create ridges and channels that help prevent runoff. Lastly, ridge-tillage involves planting crops on raised rows of soil to minimize soil erosion and runoff.
