1. Break up soil clumps: Secondary tillage helps to break up large soil clumps left behind by primary tillage, creating a finer seedbed for planting.
2. Incorporate organic matter: Secondary tillage helps to mix in organic matter, such as crop residues or compost, into the soil, improving soil structure and fertility.
3. Control weeds: Secondary tillage can help to control weeds by uprooting and burying weed seeds, as well as disrupting weed growth and development.
4. Improve soil aeration and drainage: Secondary tillage can help to improve soil aeration and drainage by loosening compacted soil and creating channels for air and water to penetrate.
5. Enhance seed-to-soil contact: Secondary tillage helps to create a firm seedbed with good seed-to-soil contact, which promotes uniform germination and emergence of crops.
6. Incorporate fertilizers and amendments: Secondary tillage can help to incorporate fertilizers and soil amendments, such as lime or gypsum, into the soil, ensuring that nutrients are available to plants.
7. Reduce soil erosion: Secondary tillage can help to reduce soil erosion by breaking up surface crusts and creating a rough soil surface that is less prone to erosion by wind and water.

Objectives of Secondary Tillage:
1. Seedbed Preparation:
- Create a fine and firm seedbed to ensure proper seed-to-soil contact for germination.
- Remove clods, weeds, and crop residue that could hinder seed placement and emergence.
2. Soil Aeration and Drainage:
- Loosen compacted soil layers, allowing for improved root penetration, water infiltration, and gas exchange.
- Improve drainage by creating channels that allow excess water to drain away.
3. Weed Control:
- Kill germinating weeds and disrupt root systems of existing weeds.
- Reduce the seed bank in the soil and prevent future weed infestations.
4. Incorporation of Amendments:
- Mix in organic matter (e.g., manure, compost), fertilizers, or other soil amendments to improve soil fertility and structure.
- Ensure uniform distribution of amendments throughout the rooting zone.
5. Moisture Conservation:
- Create a fine surface layer that acts as a mulch, reducing evaporation and conserving soil moisture.
- Establish a "crop canopy" that intercepts and retains rainfall.
6. Pest Control:
- Bury crop residue or insect pupae deep in the soil, reducing the incidence of pests and diseases.
- Create an unfavorable environment for certain soil-borne pests.
7. Disease Suppression:
- Break up disease-infected crop residues, reducing the risk of disease transmission.
- Promote soil health by increasing microbial activity, which can suppress disease pathogens.
8. Root Development:
- Create a conducive environment for root growth by breaking up compacted soil layers and creating a well-aerated seedbed.
- Allow roots to penetrate deeper into the soil, accessing more water and nutrients.
