Phosphatase activity in temperate pasture soils: Potential regulation of labile organic phosphorus turnover by phosphodiesterase activity.
Phosphatase enzymes regulate organic phosphorus (P) turnover in soil, but a clear understanding remains elusive. To investigate this, phosphomonoesterase and phosphodiesterase activities were determined by using para-nitrophenol (pNP) analogue substrates in a range of temperate pasture soils from England and Wales. Substrate-induced phosphatase activity ranged between 2.62 and 12.19 micromol pN...

lor, 1989; Wada, 1989). However, little is known about the adsorption characteristics of DOP. Only one study Leaching of dissolved organic matter (DOM) and associated nutrihas examined adsorption isotherms of DOP in natural ents can be a significant loss from developing ecosystems. We studied DOM for soils. Kaiser (2001) compared the adsorption how the adsorption of dissolved organic P (DOP) an...

abstract soil drying and rewetting (drw) cycles are considered as environmental stress that would affect the physical, chemical and biological properties of soil and nutrient cycles. the study of soil drying and rewetting effects on plant nutrition and soil fertility is very important and crucial specially their environmental effects. in this study, the effects of 1, 2, 3, 4 and 5 drying and re...
