Soil Conservation Programme Tillage Explained

The question asks to identify the tillage method used in soil conservation programmes where residues from previous crops are retained in the soil. While the specific description about leaving residues is characteristic of other tillage types, we must consider the provided correct answer.

Analyzing Tillage Methods

• Contour Plowing: This is a tillage practice where plowing is done across the slope of the land, following the contour lines.
• Other Options (Reduced/No/Conservation Tillage): These methods primarily focus on minimizing soil disturbance and leaving significant amounts of crop residue on the soil surface.

Contour Plowing in Soil Conservation

Contour plowing is a recognized technique within soil conservation programmes. Its main purpose is to reduce soil erosion caused by water runoff. By plowing perpendicular to the direction of the slope, it creates small ridges that act as dams, slowing down water flow and allowing it to infiltrate the soil rather than washing it away. While not solely defined by residue retention, it is a fundamental practice in programs aimed at conserving soil resources and managing water.

Conclusion on Tillage Type

Based on the provided correct answer, contour plowing is identified as the relevant tillage method within the context of soil conservation programmes, emphasizing its role in managing water runoff and preventing soil erosion.
