Did you have the soil tested or was that directions on the bag? Your plot will produce the best results if you get the nutrients right and the test will help with that. You could add Phosphorus if you can find bags of bone meal.I planted a food plot this weekend. The plot called for 13-13-13 fertilizer but I could only get my hands on 12-0-12 fertilizer. I thought some fertilizer would be better than none. What kind of difference will the fertilizer make??
