Ammonia volatilised from ammonium salts applied to calcareous soils was greatest from ammonium sulphate (AS), about half as much from mono‐ and di‐ammonium phosphates (MAP and DAP) and ammonium nitrate (AN), and negligible from magnesium ammonium phosphate. Losses of ammonia in 8 days from ammonium salts applied to an initially acid, sandy soil treated with calcium, barium or magnesium carbonates, were: soil treated with CaCO 3 , AS » DAP = AN; with BaCO 3 , AN » AS = DAP; with MgCO 3 , AS > AN » DAP. Reasons for these findings are discussed. It is evident that factors other than pH are operating.
