RE: Northern MN foodplots
first do a soil test! I am in Northern MI. I too share acidic sandy soil. It sucks! However, with proper lime and fertilizer I had good first year plots with a spring planting of clover and alfalfa. Then I tilled it back into the ground and planted rye, brassica, turnips and oats. Came in good too. This year I am going for some more winter greens!
