Our local Southern States Farm Supply has the following: A mix of 1/3 corn gluten, 1/3 soy bean meal, 1/3 wheat meal in pellet form. $4.95 per 50lb bag. 100% soy bean meal @ $8.95 per 50 lb bad. Or corn gluten meal @ $95 per ton. The only catch is I have to buy it by the semi-truck load. Plus delivery. Which one would be the best for an early spring application? Thanks for your input!
