First of all, let me say that the amount of nitrogen is not needed here because the rate of product is given on the label rather than trying to use the active ingredient. 50lbs. covers 17,000 sq ft and on the herbicide I am using Trimec Bentgrass formula because I have quiet a few jugs in stock. I will be applying 1 oz per m. I realize this is a weak formula but it's frosting every morning and hey, you know.
Essentially, I'll need 30 bags @ approx 12.00 = 360.00 + 4 jugs of Trimec @ 23.00 = 92.00 and it will take me a couple of days to do it. $452.00 + gasoline + about 10 hours (estimating) is the cost but I've been using 2.50 per m on pricing smaller jobs, what does everyone else charge?
I guess I'm saying forget clarity and what I'm paying for fert, if you were my competition, what would "you" charge to be competitive based on your costs where you live?
