Background Phosphorus (P) fertilizer is usually applied in excess of plant requirement and
accumulates in soils due to its strong adsorption, rapid precipitation and immobilisation into …

Phosphorus (P) affects the water–air CO2 flux through primary productivity, and affects the
changes of carbon cycle and ecological environment in the global world. Organic …

Phosphorus (P) is an indispensable element for all life on Earth and, during the past decade,
concerns about the future of its global supply have stimulated much research on soil P and …

Organic phosphorus (OP) is one of the main forms of phosphorus in lake ecosystems.
Mounting evidence has shown that sediment OP has become a major but underestimated …

Phosphorus nuclear magnetic resonance (31P NMR) spectroscopy is an important tool for
the study of soil P and has significantly advanced our knowledge of soil P forms, particularly …

The technique of 31 P-NMR spectroscopy has done more to advance the knowledge of
organic P forms in environmental samples than any other method. Early 31 P-NMR work …

Understanding legacy phosphorus (P) build-up and draw-down from long-term fertilization is
essential for effective P management. Using replicated plots from Saskatchewan, Canada …

Animal manure consists of predominantly urine and feces, but also may contain bedding
materials, dropped feed, scurf, and other farming wastes. Manure is typically applied to soils …

Abstract Background and Aims Phosphorus (P) mineralisation from crop residues is usually
predicted from total P or carbon: phosphorus (C: P) ratios. However, these measures have …

Anthropogenic nutrient enrichment has caused phosphorus (P) accumulation in many
freshwater sediments, raising concerns that internal loading from legacy P may delay the …
