Abstract

Phosphomonoesterase activities were determined monthly during a seasonal cycle in three characteristic soil types of the English
uplands that have been subject to long-term atmospheric nitrogen deposition. Activities (moll para-nitrophenol ri soil dry wt.
h-1) ranged between 83.9 and 307 in a blanket peat (total carbon 318 mg g-1, pH 3.9), 45.2-86.4 in an acid organic grassland soil
(total carbon 354 mg g-1, pH 3.7) and 10.4-21.1 in a calcareous grassland soil (total carbon 140 mg g-1, pH 7.3). These are
amongst the highest reported soil phosphomonoesterase activities and confirm the strong biological phosphorus limitation in this
environment
