HI Byron, The nitrogen percentage in the fertilizer you use should depend on what vegetable you are fertilizing. Cabbage family, greens etc. should be fertilized with a high nitrogen content like 21-0-0 because foliage is what you want. Other crops have different requirements. I use a 10-20-10 at planting time for most vegetables. Later as a side dressing depending upon the requirements of that particular vegetable I may use 21-0-0, 13-13-13, or more 10-20-10.
