Coldwater, Michigan | It might make more sense if you open the attachment in the original post, which basically says the same thing, except it is laid out visually a bit better. The idea behind it is you can compare the cost of a program against it's additional Yield, or lack thereof. If for instance your 10-34-0 was costing you $7.00/gallon, and you were using 5 gallons of it on the seed, that would cost you $35/acre vs the Major 6-24-6 at possibly $9.00/gallon @ 5 gallons per acre on the seed, that would cost you $45/acre. If you take the Michigan results, the Major 6-24-6 yielded 5.3 BPA more yield than the seed placed 10-34-0 @ 5 gallons. 5.3 BPA x $5/bushel (corn) = $26.50 return prior to deducting the cost differences.
So the 6-24-6 is ahead $26.50/a, but cost $10/acre more ($26.50 - $10.00 cost difference) =!6.50/a more money in your pocket than if you had used the 10-34-0 on the seed.
Another example: 10-34-0 @ 15 gallons/acre 2" x 2" vs Major 6-24-6 @ 5 gallons on the seed. 10-34-0 cost $7.00/gal x 15 gallons = $105/acre cost. Major 6-24-6 @ 5gallons/acre on seed @ $9.00 = $45/acre cost. Difference in cost = $60/acre in favor of 6-24-6 material. Yield difference in favor of Major 6-24-6 = 2.4 BPA x $5/Bushel =$12/acre, plus it is $60/acre cheaper to use. That is $72.00/acre more in your pocket compared to using the 10-34-0 program @ 15 gallons.
The information provided in the original post will let you plug in your own numbers. I would encourage it, because depending on where (price-wise) you buy your products this equation changes. If for instance my prices are high for the 10-34-0, and low for the 6-24-6, the result changes in favor of the 10-34-0 if that difference in prices is great enough.
I hope that helps your understanding of what I was trying to get across. Thanks for bringing it up!
