Which condition is least likely when using a no-till system that maintains crop residue?

In a no-till system that maintains crop residue, the condition that is least likely is warmer soil temperature. This is because the presence of crop residue on the soil surface acts as an insulating layer that can trap cooler air and moisture beneath it. As a result, it can actually delay soil warming in the spring compared to bare soil, which can absorb sunlight more readily.

In contrast, more water infiltration and less wind erosion are enhanced by maintaining crop residue. The residue helps to break the impact of raindrops on the soil, promoting better water infiltration and reducing surface runoff. Additionally, it acts as a protective barrier against wind erosion, keeping the soil more stable and reducing the loss of topsoil.

Less evaporation is also a benefit of this system, as the residue helps to keep soil moisture levels higher by creating shade and reducing the direct impact of wind and sunlight on the soil surface. Together, these benefits emphasize the importance of maintaining crop residue in no-till systems for soil health and moisture retention.
