Question

There are certain methods to conserve soil in plain areas and on hill slopes. Which of the following statements about soil conservation practices is/are true?

• A. Crop rotation enables farmers to increase soil's organic matter content, soil structure, and rooting depth.
• B. Cover cropping and mulching reduces soil displacement associated with the impact of raindrops hitting soil particles.
• C. Conservation tillage is aimed at preserving soil aggregates, organic matter and surface residue from previous crops.
• D. Cross slope farming creates vegetative areas that separate field boundaries from watercourses.

Answer 1

Answer: (A), (B), (C)

Conservation tillage is aimed at preserving soil aggregates, organic matter and surface residue from previous crops.

Sustainable land management and soil conservation practices are required to prevent soil erosion and land degradation. Some of the soil conservation practices include crop rotation, mulching, conservation tillage, cross-slope farming, and creating buffer strips or grassed waterways. All these practices reduce the exposure of topsoil to the forces of running water and wind. They also build organic matter and enhance soil health.
