No-till cropping is a practice aimed at which outcome?

• A. Increasing irrigation needs
• B. Reducing soil erosion
• C. Raising pest problems
• D. Increasing soil compaction

Answer: (B)

No-till cropping focuses on protecting the soil surface to prevent erosion. By not disturbing the soil and leaving crop residues on the field, the surface is covered and shielded from the impact of raindrops and from strong winds. That protective cover reduces the energy of rainfall hitting the soil, helps water infiltrate rather than running off, and keeps the nutrient-rich topsoil in place. Over time, this practice also helps build soil organic matter and improves soil structure, which further enhances stability and reduces the likelihood of erosion.

It’s not about increasing irrigation needs, pest problems, or soil compaction as the main goal. While those factors can be influenced by farming practices, the primary reason for no-till is to minimize soil erosion and protect the soil’s health.
