A moldboard plow is a farming tool designed to turn over soil, preparing it for planting. It features a curved metal blade, known as the moldboard, which lifts and flips the soil as it moves through the ground. This process helps to bury weeds and crop residues, improving soil aeration and nutrient availability. The moldboard plow is often pulled by a tractor or draft animals, making it efficient for large fields. It has been a crucial development in agriculture since its invention, allowing farmers to cultivate land more effectively and increase crop yields.
