I agree with ronfromramer about getting a soil sample. It will tell you exactly what you need. I get all of mine done at Auburn. The nice thing is they will keep your soil info in a database. This allows you to input anything you might want to plant in that food plot and it will in turn give you the fertilizer needed.
With that said, I wouldn't ever put anything with nitrogen (the first number) on peas. The peas don't need it and all it will do is help the weeds grow.
We got soil samples on everyone of our plots. Some of them only needed the middle number (phosphorous) and some needed the middle and last number (phosphorous and potassium) for planting peas. It just depends on the soil.
