That's high for bulk. Scruggs here has triple 17 for $10.50/bag. You numbers would make it $12/bag. I'd certainly expect bulk to be cheaper.
All depends on what is used to make it. Scruggs bagged fert is using urea as the N source. Which will be some cheaper. Does the bulk blend have any sulfur? Which will be better than plain urea. Or is it made it Am Nitrate? Lot of variables come it to play when pricing Fertilizer. And he’s getting to use a very expensive buggy.
Like 257 said. If you are getting bulk blend it to your soul test. No need for paying for something you don’t need. And have them work out all of the filler. That 17-17-17 rem270 is talking about will have some filler. Because it’s made with all urea for the N source. Now then if you have some with Am nitrate it will be very little to none. Or if it is a 17-17-17-5s it won’t have any.
