The Green Revolution Practice Test

Planting cover crops and adding compost or manure, which increases carbon inputs to soil and supports microbial communities.

Deep plowing every season, which accelerates oxidation of organic matter and increases long‑term soil carbon storage.

Removing crop residues after harvest, which prevents pests and therefore increases soil organic matter through reduced decomposition.

Increasing pesticide applications, which adds carbon directly to soil and replaces the need for plant residues.
