    i think i know the answer, lets see if anyone else does. if a 50 lb bag of fertilizer , rated to treat 12,500 sq ft of turf, has the numbers 20-10-10 on it, how many lbs of nitrogen per k is being applied?

    50/12.5 = 4 lbs fert / 1000

    4 x .2 = .8 lbs N / 1000

    It all depends on the person behind the spreader.

    50*20%=10lbs
    10/12.5=.8lbsN per 1k

    Interesting how lars got there. I didn't think of it that way.

    I believe both are right though?
