I could be. If it’s all calcium (which it’s not)…. 5 gallons per acre of solid calcium would be 40 lbs per acre. You need to be in the hundreds of lbs for sure. Lot of variables on your soil (type of soil, ECCE & lime buffer capacity - disregard for this post) … but if it’s acidic …. It’s gonna be hundreds to thousands of lbs needed per acre. Doesn’t matter what form it’s in, calcium in most potent form will require way more than can be applied by liquid.
**ok, so that’s 10% calcium…. That’s 4 lbs calcium per 5 gallons of actual product sprayed. I’d like to see a guy START with 100x that amount. There’s some acidic soils in s iowa that I’ve seen that have called for 20,000 lbs of lime per acre. That’s the worst I’ve seen. When doing Des Moines water works lime which breaks down fast & higher calcium rates, most my soils call for about 4,000 lbs per acre.
