This answer maybe different for other countries, but here in North American no such crop exists. Farmers may just leave the field untilled until next year, or not till at all and instead adopt no-till practices for producing next year's harvest.
A cover crop. Cover crops are sometimes legumes to help add nitrogen to the soil, sometimes just broad-leaved crops to protect the soil, and sometimes just grasses to help add organic matter to the soil.
Some of these crops are called cover crops.
Legumes can be planted between harvests to reduce soil erosion. It also helps add nitrogen and other organic matters to the soil.
That is a cover crop.
Restoration- which is required by law. Mining companies must post a bond to reclaim land that has been mined. It will be contoured to reduce erosion and seeded with grasses and/or planted with trees.
We can reduce erosion farting less, burping less and catching rainwater in our mouths
The planting of more trees can protect soil from wind and water erosion. The terracing of hillsides also helps to reduce the effects of erosion.
Vegetation.
It blocks the erosion from happening. That is why it prevents/reduces the effects of erosion
yes
reduce
make dams
Surrrounding the erosion with trees will in the highest degree help reduce the erosion.
