I need help. I have a garden about 50'x100' and right now it is just dirt. I planted sweet corn tomatoes and peas in it this spring and they all did very well considering the drought but I planted winter wheat as a cover crop and I can see very well where the sweet corn ground is depleated of nitrogen. How do I make that soil healthier again? I know fertilizer, but what kind, I need suggestions. Next year will be my second year at this and I want another success. Thanks for you help. Also I have a compost pile but there is not near enough there to go around the whole garden.
