Why would farmers plant alfalfa that has less economic value
arlik [135]

answer:

because it benefits the soil. the long alfalfa stand life also gives the soil a chance to rest from frequent field crop rotations, helps provide nitrogen for subsequent crops, and improves soil tilth. this helps prevent pesticide and sediment movement to natural waterways.

good luck :)

hopefully, this helps

have a great day !!
