Save your soil with a cover crop
If you are not planning a fall vegetable garden, it’s worth your while to consider a cover crop of rye or winter wheat. Your corn, beans, tomatoes, lettuce and pepper plants may not have used all of the nutrients in the soil. Even if you did not apply more fertilizer than the plants needed, even if you are an organic grower, there is organic matter in the soil that continues to decompose, releasing nutrients until the ground freezes.
