Clean Tillage is a type of tillage practice in agriculture where the soil of the entire field is worked in such a way that no living plant is left undisturbed. This process is done to control weeds, soil-borne pathogens, and pests. The process of clean tillage involves several steps, which are discussed below:

Steps involved in Clean Tillage:

1. Preparing the Field: Before starting the clean tillage process, the field is prepared by removing any debris or plant residues left after the previous crop. This is done to ensure that the soil is free from any obstacles that may interfere with the tillage process.

2. Plowing the Soil: The next step involves plowing the soil using a plow or a disc to loosen the soil and make it ready for planting. This process also helps to mix any remaining plant residues with the soil, which will eventually decompose and add nutrients to the soil.

3. Harrowing the Soil: After plowing, the soil is harrowed to break up any large clumps of soil and to create a level seedbed. This process also helps to incorporate any remaining plant residues into the soil.

4. Seeding or Planting: Once the soil is prepared, seeds or seedlings are planted according to the crop being grown.

Benefits of Clean Tillage:

1. Weed Control: Clean tillage helps to control weeds by disturbing the soil and burying weed seeds that may be present on the surface.

2. Pest Control: Tillage helps to control pests by disturbing their habitat and exposing them to predators and other natural enemies.

3. Soil-borne Pathogen Control: Clean tillage helps to control soil-borne pathogens by burying any infected plant residues that may be present on the surface.

4. Improved Soil Structure: Tillage helps to improve soil structure by loosening compacted soil and creating a better environment for plant growth.

5. Nutrient Management: Tillage helps to mix plant residues into the soil, which eventually decompose and add nutrients to the soil.

In conclusion, Clean Tillage is an important tillage practice in agriculture that helps to control weeds, pests, and soil-borne pathogens while improving soil structure and nutrient management.
