Unlimed or under limed manure can also produces hydrogen sulfide (H2S) which is also an acid and because of the sulfur component it has a similar smell and a low PH like sulfur dioxide SO2. Hydrogen sulfide in manure results from the bacterial breakdown of organic matter, in the absence of oxygen, this process is commonly known as anaerobic digestion.
But here is the important part! I would be more worried about an over limed manure. They do that so it doesn’t stink as much. And if you did buy an over limed manure and added lime to it, you have even more of a problem. Add to that, that some water wells are much higher in PH than others and your soils PH could be higher than you might imagine.
You really should check the PH of your soil at this point.
Augie, was this Black Kow bagged or in bulk? Did you add lime to your container soil?
