Which of the following is not an advantage of composting? a. protecting soil from erosion b. compost can come from any kind of material c. reducing the need for fertilizers

Composting does protect soil from erosion. 

Compost cannot come from any material... Compost must be made up of natural materials that decompose. 

Composting does reduce the need for fertilizer because it creates its own. 

The answer would be B. compost can come from any kind of material because it is false. 

I hope this helps!
