What are the three types of conservation tillage?

Conservation tillage is a farming practice that aims to reduce soil erosion and improve soil health by minimizing soil disturbance. The three primary types of conservation tillage are no-till, mulch-till, and ridge-till.

No-till farming involves planting crops directly into undisturbed soil, which helps retain moisture and organic matter while minimizing soil erosion. This method enhances soil structure and promotes beneficial microbial activity.

Mulch-till, on the other hand, involves tilling the soil but leaving a significant portion of the previous crop's residue on the surface. This residue provides ground cover, which can help reduce erosion, improve water retention, and enhance soil health by maintaining organic content in the soil.

Ridge-till cultivates in raised rows while maintaining vegetation cover between the rows. This method effectively reduces erosion and allows for better water management while also capitalizing on warm, dry conditions in raised beds.

The other options listed include methods that either do not fall under conservation tillage or include techniques primarily associated with conventional tillage, which generally involve more soil disturbance and higher risks of erosion. Thus, the answer that identifies no-till, mulch-till, and ridge-till as the three types of conservation tillage is the most accurate.
