Buy the Rubbermaid tubs they sell at places like Menards. The savings on your first "buy" of fertilizer will pay for them. I buy mine in Big Lake at the fertilizer "place" and load the tub using 5 gallon buckets from their bulk bins. It took me 10 minutes to load 850# of Urea that cost $550 a ton. I weigh in and out on their truck scale. If I bought it in bags, it would cost twice as much. Urea will blow out a bit if you don't use a lid and use a trailer. I just top it off with a thin payer of potash and it won't go anywhere. So much easier to load bins in my trailer than loading bins in the back of my truck with a topper. I don't like using lids during transport because you can lose them in the trailer driving. I then can store the bins with the lid on at the farm and they will last forever. This way you can buy off season and save even more on prices. Buy the individual components like Urea, Potash and DAP (diammonium phosphate) and mix it your self as you use it. It is so much easier to deal with and buy this way. Just a reminder that the smaller tubs work better...especially for Potash and DAP because it so much heavier than Urea. I used to line my pickup bed with a tarp and then have them dump 1500# in the back. But then you had to shovel it out and rinse out your truck extra good. It does not take much Potash to start rust!!!!!!!! The tubs are the way to go. Then in the fall the neighbor picks a couple of acre of corn for me. I then load all my empty tubs of corn and bring it home to feed the deer and ducks in my yard. Keeping the corn in tubs keeps it dry and mouse proof.
