The plough is a primary cultivation tool which has been used in its various forms for many centuries as the first step in seedbed preparation. The main aims of ploughing include:

• Complete burial of surface trash, crop residues and farmyard manure.

• Improvement of drainage and air movement through the soil.

• Restoration of soil structure damaged by heavy farm machinery.

Leaving the land in a condition which permits production of seedbeds with the minimum number of passes with cultivation machinery.

Primary tillage implements are generally used on uncultivated land or after the harvest of the previous crop to break down the soil and incorporate plant residues. Implements used for primary tillage are ploughs, subsoilers and e.c.

Plowing is still the most common primary tillage operation carried out after harvesting a crop. Implements used for plowing are moldboard plows, disk plows, chisel plows and rotary plows.
