Cover crops are the real heroes in the world of agriculture. Their job starts after a field is harvested and ends just before the next season’s crop is planted. Expectations for cover crops are high because if they don’t produce, the next crop may suffer.
After crops are harvested each year, planting fields are left bare. Runoff from rainwater, wind, and other forms of erosion devastate planting fields by stripping essential nutrients from the soil – nutrients needed for the next growing season. In addition to the loss of vital nutrients, the exposed fields are prime real estate for noxious-weed seeds intent on stealing what is left of the field’s nutrients. Replacing the lost nutrients and removing the weedy invaders costs millions of dollars each year for farmers.
