Tillage is primarily used for which of the following?

Tillage is primarily utilized for controlling weeds and aerating the soil. This farming practice involves the mechanical manipulation of the soil, which helps to break up compacted soil layers, allowing for increased air and water penetration. The act of tilling disrupts the growth of weeds, making it easier to manage unwanted vegetation that competes with crops for nutrients and water.

By aerating the soil, tillage enhances the conditions for root growth and promotes the activity of beneficial soil microorganisms, which contribute to the overall health and fertility of the soil. While tillage can have other impacts, such as on erosion, its primary function revolves around these two key aspects: weed control and soil aeration.
