I've seen manure from the same tank/dragline on the same field vary in N content by a wide margin. Depending on how it's been agitated, how full or empty the pit is, etc.
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.
