How do cover crops contribute to sustainable agriculture?
-
How do cover crops contribute to sustainable agriculture?
-
Inducing plant mutations
-
Enhancing seed germination
-
Boosting nitrogen levels in the soil
Correct Answer
A. How do cover crops contribute to sustainable agriculture?Explanation
Cover crops contribute to sustainable agriculture by suppressing weeds and improving soil health. Their dense canopy inhibits weed growth, reducing the need for herbicides. As cover crops decompose, they add organic matter to the soil, enhancing fertility and water retention. Some cover crops, like legumes, fix atmospheric nitrogen, enriching the soil. Their extensive root systems improve soil structure, aiding water infiltration and nutrient uptake.Rate this question:
