Question: 1 / 400

What is vegetation produced with the intent of plowing it in to improve the organic matter content termed?

Green manure

The practice of using vegetation with the intent of plowing it in to enhance the organic matter content of the soil is termed green manure. Green manure crops are typically grown specifically to be tilled back into the soil. This process enriches the soil with organic materials, improves soil structure, and promotes moisture retention, ultimately benefiting subsequent crops.

In contrast, cover crops are primarily planted to prevent soil erosion, suppress weeds, and maintain soil health, but they may not always be tilled back into the soil before cash crops are sown. Compost refers to organic matter that has been decomposed and is used as a fertilizer, while mulch is material applied to the surface of the soil to retain moisture and suppress weeds, rather than being mixed into the soil. Thus, the correct term for vegetation intended for this specific purpose is green manure.
