Nitrification of mineralised NH 4 ‐N was enhanced by long‐term laboratory storage in polyethylene bags. Such storage caused a slight decrease in soil pH, possibly due to release of acids from decomposing organic matter. Long‐term oven‐drying of soils released substantial amounts of NH 4 ‐N; the NO 3 ‐N remained practically unchanged. The magnitude of released NH 4 ‐N was noted to be dependent upon the organic matter content of soils. It was speculated that the released NH 4 ‐N came from the splitting of ammonium from N‐bearing organic compounds in these soils.
