    I use Lesco granulated iron micronutrient package on all my warm season turf.
    It averages around 100-105* daily with humidity above 80%, and the results are nothing short of great.
    The soil conditions/type I encounter means I apply once every quarter.

    i tested my soil PH and it was alkaline so i need to raise the acidity level.figure iron would work.correct?

    So, you need Fe and N. So why not use a slow realeased balanced fertilizer? What kind of grass is it? I know its warm season, so how about Lesco 28-5-10 50%SCU 4.5% FE?
