ABSTRACT: We assessed the addition Mg and P salts to promote struvite crystallization and mitigate reactive N losses from a rotating drum (12 m3 ) used for in-vessel composting of swine manure. The tested treatments were: mixture of sawdust and swine manure (baseline) and the same mixture with the addition of magnesium sulfate and phosphoric acid (MgSO4+H3PO4). Struvite crystallization decreased NH3-N and TN losses by 96.5 and 46%, respectively. Higher N2O-N emissions were related with resolubilization of the struvite under lower pH conditions. Further research is needed to assess strategies for the stabilization of struvite crystals, minoring N losses and increasing nutrient concentration value of the organic compost. |
