What type of conservation tillage leaves the greatest amount of soil cover by crop residues? What are the advantages and disadvantages of this system?

No-till conservation tillage

Explanation:

No till conservation involves the soil not being touched which gives rise to a large amount of organic matter being left on the surface.

The Advantage of this method is that it helps to prevent erosion such as that of wind and water due to the little or no exposure of the soil surface and helps to provide nutrients to the plants through the organic matter present.

The Disadvantage of this method is its heavy reliance of chemicals such as herbicides in killing the weeds in order to prevent competition for vital compounds with the main plants.
