What detrimental effect do rototillers have on soil?

1. Improve soil structure

2. Enhance drainage

3. Destroy soil structure

4. Increase soil fertility

The correct answer is: Destroy soil structure

Rototillers can have a detrimental effect on soil because they disrupt the natural structure of the soil. When the soil is tilled, it can lead to the breakdown of soil aggregates, which are clusters of soil particles that bind together. These aggregates are essential for maintaining a healthy soil structure, as they facilitate movement of air and water through the soil, support root growth, and provide habitat for beneficial microorganisms. By destroying the soil structure, rototillers can also lead to increased soil compaction at deeper levels, reduced water infiltration, and ultimately, a decline in soil health. Such disruption makes the soil more prone to erosion and can negatively affect plant growth due to reduced access to nutrients and water. Therefore, understanding the impact of rototilling on soil structure is crucial for sustainable soil management practices.
