back furrow

A back furrow is a ridge of soil left on the sides when plowing by throwing soil from the first two furrows together. This is a technique within tillage, which is the mechanical preparation and cultivation of soil for planting. Tillage aims to create a suitable environment for seeds and roots by modifying soil structure, managing crop residues, and controlling weeds.123

Different types of plows, such as moldboard, disk, and chisel plows, are used for primary tillage to break and loosen soil. The way plowing is done can result in ridges (back furrows) or trenches (dead furrows). Modern agriculture also employs minimum tillage and no-till methods to preserve soil structure and reduce erosion.32
