A moldboard is a crucial component of a plow, designed to turn and aerate the soil during farming. It is typically a curved or angled plate that helps to lift and flip the soil, creating furrows for planting. The shape of the moldboard allows it to efficiently slice through the ground, making it easier for farmers to prepare their fields. Moldboards can vary in design, depending on the type of plow and the specific farming needs. Common types include the share moldboard and the reversible moldboard, each serving different purposes in soil management. Proper use of a moldboard can enhance crop yields by improving soil structure and drainage.
