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…

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,

Acidified Animal Manure Products Combined with a Nitrification Inhibitor Can Serve as a Starter Fertilizer for Maize

There is an urgent need for better management practices regarding livestock farm nutrient imbalances and for finding alternatives to the actual use of mineral fertilizers. Acidification of animal

Acidification Effects on In Situ Ammonia Emissions and Cereal Yields Depending on Slurry Type and Application Method

Field application of organic slurries contributes considerably to emissions of ammonia (NH3) which causes sever environmental damage and can result in lower nitrogen (N) fertilizer efficiency. In

One-Time Acidification of Slurry: What Is the Most Effective Acid and Treatment Strategy?

Acidification of slurry is a common practice to reduce ammonia and methane emissions. Sulfuric acid is usually used for this process. However, this has been criticized due to the high sulfur input




Under anaerobic conditions, organic compounds containing sulfur break down, forming intermediate sulfurcontaining compounds that ultimately form hydrogen sulfide. The objectives of this project were

Passive treatment of acid mine drainage in bioreactors using sulfate-reducing bacteria: critical review and research needs.

Critical parameters for design and long-term operation of sulfate-reducing passive bioreactors, and several studies conducted to find the best mixture of natural organic substrates for SRB are reviewed.

Chemical Characterisation of Organic Electron Donors For Sulfate Reduction For Potential Use in Acid Mine Drainage Treatment

The chemical composition of the carbon source severely impacted its capacity to drive sulfate reduction and may be used to assist in predicting the sulfate Reduction capacity of a carbon source.

Plant availability of catch crop sulfur following spring incorporation

Catch crops might reduce sulphate leaching and thereby increase the overall S use efficiency in crop rotations. At 2 experimental sites in Denmark (a sandy loam and a coarse sand) S uptake of catch

Organic Manures as Sources of Fertiliser Sulphur

On a global scale, S excretion from domestic animals may be estimated to around 8 million t per year, corresponding to 80% of the World S consumption for mineral fertiliser manufacture. The

The effects of sediment slurrying on microbial processes, and the role of amino acids as substrates for sulfate reduction in anoxic marine sediments

In sediment slurry experiments with anoxic marine sediments collected in Cape Lookout Bight, NC, and a site in mid-Chesapeake Bay, the rates of sulfate reduction and ammonium production decrease with
