I’m not even sure you could take a quart of hog manure from a pit, stir it up and divide it in 2 bottles, send both bottles to the same lab (label them as if they are from different pits) and get the same test results for both jars.
Bottom line is, hog manure is not a consistent product like 28/32, urea or anhydrous and it is 100x harder to do an even job of application than when using commercial fertilizers. 10-15 gallons of 28/32 per acre, either pre plant or pre emerge weed & feed or side dressed, will cover up a lot of discrepancies in application rates and fertilizer value.
