This document discusses farming techniques and their influence on agricultural patterns. It describes the processes of ploughing, sowing, and harvesting. Ploughing involves loosening the soil to bring nutrients to the surface and allow water to reach seeds. Sowing is placing seeds in ploughed soil and covering them. Harvesting occurs when crops are fully grown and ready to be collected from fields. The document also contrasts old and new farming methods, noting that old farms were smaller and relied more on human and animal labor while new farms are larger and use machinery.
