Product description

At the pig farm owned by Mr. Kris Casier, NH3 emission from the pig manure is recovered by scrubbing with sulphuric acid. The resulted ammonium sulphate is a brown-colored liquid with a pH at 4,6-6,1, depending on the adjustment of the acid scrubber. The product usually contains 41 g/kg of N in the form of NH4-N, which is supposed to be 100% directly available for plants. Due to the highly concentrated N in ammonium sulphate, compared to animal manure, lower amount is needed for agricultural application. In addition, the ammonium sulphate also contains around 100 g/L SO42- providing 30 g/kg of sulphur (S). This allows the product to perfectly meet the nitrogen and especially sulphur requirements of crops. Therefore, this ammonium sulphate can be applied as a liquid fertiliser to substitute synthetic fertilisers.

Based on soil analysis results (N & S), the crop requirement and the soil type, etc. the correct dosage should be calculated. In order to reduce the risk of emission during application, it is recommended to apply the ammonium sulphate solution via injection or immediately incorporated into soil after surface application.
