Acidification of slurry with sulfuric acid is a recent agricultural practice that may serve a double purpose: reducing ammonia emission and ensuring crop sulfur sufficiency. We investigated S transformations in untreated and acidified pig slurry stored for up to 11 mo at 2, 10, or 20 degrees C. Furthermore, the fertilizer efficiency of sulfuric acid in acidified slurry was investigated in a pot experiment with spring barley. The sulfate content from acidification with sulfuric acid was…

Effects of slurry acidification with sulphuric acid combined with aeration on the turnover and plant availability of nitrogen

Sulfur turnover and emissions during storage of cattle slurry: effects of acidification and sulfur addition.

Generally, addition of a sulfate increased the contribution from HS dramatically, whereas acidification lowered the HS contribution but increased that of MT, so acidification of slurry with sulfuric acid may potentially produce more odor from S compounds than untreated slurry.

Effects of cattle slurry acidification on ammonia and methane evolution during storage.

The study suggests that complex microbial interactions involving sulfur transformations and pH determine the potential for CH(4) emission during storage of cattle slurry, and that slurry acidification may be a cost-effective greenhouse gas mitigation option.

Impact of cattle slurry acidification on carbon and nitrogen dynamics during storage and after soil incorporation

Acidification of animal slurry is recommended in order to reduce NH3 emissions, but relatively little is known about the effect of such treatment on C and N dynamics during acidification, storage,…
