What is a good plant for spring food plots with a low pH soil. I had two different places cleared off last fall that have a pH of 4.9. One spot is about an acre the other is probably three acres. With lime prices doubling from last year I can't put the lime on them like they need. I mainly want something planted to keep the soil from washing and to build organic matter. I had thought about buckwheat or maybe sorghum mixed with cowpeas, just not sure how they would do. What would be a good thing to plant with these conditions. I will put some lime on it but I cannot get anywhere close to the recommendation of 5000lbs per acre.
