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 aerate the soil and bury weeds, making it easier for crops to grow. The moldboard plow is often pulled by a tractor or draft animals, allowing farmers to cover larger areas efficiently. It has been a crucial development in agriculture since its invention, significantly improving soil management and crop yields compared to traditional hand tools.
