Conservation Tillage prioritizes reducing soil erosion by maintaining crop residues on the soil surface, thereby protecting it from wind and water erosion.

While Conservation Tillage offers numerous benefits, it may not directly lead to enhanced crop yield. Its primary focus is on soil conservation and health, which can indirectly contribute to improved crop growth and yield.

The fundamental distinction between Conventional Tillage and Conservation Tillage lies in the frequency of tillage operations. Conservation Tillage minimizes tillage, while Conventional Tillage involves frequent and intensive tillage.

No-till farming is the most effective Conservation Tillage technique in terms of residue cover. It leaves at least 30% of the soil surface covered with crop residues, providing maximum protection against erosion.

Crop rotation in Conservation Tillage aims to improve soil fertility by diversifying crops and their root systems, thereby enhancing nutrient cycling and reducing the risk of nutrient depletion.

Rice is not typically grown using Conservation Tillage methods due to its specific water requirements and the challenges of managing crop residues in flooded conditions.

Conservation Tillage contributes to carbon sequestration through various mechanisms, including reducing soil erosion, increasing crop residue cover, and promoting microbial activity in the soil, which enhances the storage of carbon.

In Conservation Tillage, tillage depth is typically kept shallow, less than 5 centimeters, to minimize soil disturbance and preserve crop residues on the soil surface.

Ridge-till farming is a Conservation Tillage technique that involves creating small ridges on the soil surface, typically during the planting operation. These ridges help in managing crop residues, improving drainage, and reducing soil erosion.

The impact of Conservation Tillage on soil moisture levels can vary depending on soil type, climate conditions, and management practices. In general, it can help conserve soil moisture by reducing evaporation and promoting water infiltration.

Increased weed pressure is a common challenge associated with Conservation Tillage, particularly in the initial stages of adoption. Crop residues left on the soil surface can provide a favorable environment for weed growth.

Farmers can overcome the challenge of increased weed pressure in Conservation Tillage by employing a combination of strategies, including using herbicides judiciously, implementing crop rotation, and adjusting planting dates to minimize weed competition.

In India, the Ministry of Agriculture and Farmers Welfare, the Ministry of Environment, Forest and Climate Change, and the Indian Council of Agricultural Research work collaboratively to promote Conservation Tillage practices and provide support to farmers adopting these methods.

Conservation Tillage, when practiced consistently over time, can lead to increased soil organic matter content, improved soil structure, and enhanced soil biodiversity, resulting in improved soil health and productivity.
