Soil phosphorus (P) cycling in agroecosystems is highly complex, with many chemical,
physical, and biological processes affecting the availability of P to plants. Traditionally, P …

Potential enzyme activities in soil and water samples are measured by addition of an excess
amount of suitable substrate and subsequent determination of product release. If the …

The speciation of dissolved organic phosphorus (DOP) in the temperate Tamar estuary of
SW England is described. Eight stations from the riverine to marine end-members were …

Phosphorus (P) is an essential element for living cells, and to some extent the abundance
and activity of all organisms are regulated by P availability. However, the importance of P in …

Redox-driven internal phosphorus (P) loading from lake sediments is a key process for
propagating and sustaining cyanobacterial blooms in freshwater lakes. Missisquoi Bay in …

Internal phosphorus (P) in sediments plays an important role in the nutrient dynamics of
lakes, sometimes long after external loads have been reduced. Similarly, internal P sources …

Phosphorus (P) forms determined by 31 P nuclear magnetic resonance spectroscopy (31 P-
NMR) are compositional data (ie, parts of some whole bounded between 0 and the unit of …

Phosphorous (P) cycling is often closely coupled to iron (Fe), particularly following mineral
weathering or in hydromorphic soils where Fe redox reactions can control the equilibrium …

Chemical forms of phosphorus (P) in airborne particulate matter (PM) are poorly known and
do not correlate with solubility or extraction measurements commonly used to infer …

Phenol oxidases are a group of extracellular enzymes that catalyze the oxidation of lignin
and phenolic compounds in soil organic matter. Despite their importance, little is known …
