I agree with axe, here, and would add: the rate of application you choose should be tailored to the N source and type of extended release, if any. Also, think in terms of season-long ratios and rates. If you are removing clippings, assume you are mining K out of your lawns and adjust accordingly - some say this can be as much as 1# K/M per year.
