    ABSTRACTAnalysis of fixed ammonium (NH4+) in soils by the most common method requires the subsample to be ground to pass through a 100-mesh sieve. We tested a hypothesis that the ball milling pretreatment for the analysis of fixed NH4+ may influence the analytical results depending on the content of exchangeable NH4+. Five paddy soils collected from the surface layer in Japan were treated with .
