Which of the following describes a characteristic of conservation tillage?

Conservation tillage is characterized by its practice of maintaining a cover of crop residue on the soil surface. This approach helps to protect the soil from erosion, retain moisture, and enhance soil health by promoting biodiversity and improving organic matter content. The crop residue acts as a protective barrier against weather elements, reduces the intensity of rain impact, and aids in controlling weeds, all of which contribute to improved soil structure and overall ecosystem functionality.

Maintaining crop residue on the surface is significant because it improves water infiltration and reduces runoff, ultimately leading to better nutrient availability for crops. This practice stands in contrast to traditional tillage methods that often involve disturbing the soil extensively, which can lead to loss of soil structure and increased erosion.
