A mouldboard plough is a farming tool used to turn over soil, preparing it for planting. It consists of a curved blade, called a mouldboard, 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. Mouldboard ploughs can be pulled by animals or tractors, making them versatile for different farming practices. They are essential in agriculture, as they improve soil structure and fertility, contributing to better crop yields. The design has evolved over time, but the basic principle remains the same.
