It isn't the analysis that burns your lawn...it is the application rate and the amount of SCU in the product. I am currently using a 32-3-8 30%SCU. However I have backed my rate down to 2#/1000 and will be swithing to a 50% SCU very soon.
If you are comparing the same analysis of "organic" vs. chemical fertilizer you should get the same response. N-P-K is N-P-K. The plants don't know the difference when you apply at the correct rate and use SCU.
