NE Iowa | I assume they took 5.9 percent off either the price or the "wet" buschels which is not far off of what most places charge. However, most places charge shrink and drying separately where I assume yours was combined. Most elevators I know of shrink 1.4% per 1% of moisture over 15% so in your case 1.9 X 1.4% = 2.66%. My local elevators charge $.035 per 1% of moisture over 15%. So in your case 1.9 x $.035 = $.0665 per bu. At $3.50 per bu $.0665 is 1.9%. So 2.66% shrink + 1.9% drying 4.56% total dockage at my "typical" elevator. You got docked 5.9% which is roughly $.05 per bu more than what I say in normal.
Now lets say you dry it yourself with air. I natural air dry all my corn and it costs about $.02 per point in electricity. Lets also say that with air drying you need to overdry the bottom before the top is dry. Most bins that I empty probably average 14% moisture. Drying your ~17% corn to 14% would cost you about $.06 per bu. $.06 is 1.71% at $3.50 per bu. If you dry corn from 16.9% to 14% you will lose at least the 1.18% per point of "actual" shrink that is inevitable. So 2.9 X 1.18 = 3.54% in shrink. So 1.71% drying cost + 3.54% shrink = 5.25% loss. So if you air dried yourself and overdried it only 1% down to 14% you could have saved a little ($.02/bu). If you could have controlled the air drying a little better you could have save a little more but it also could have went the other way.
Shrink happens whether you dry it or the elevator does and drying anywhere has a cost. | |
