Organic phosphorus (P) plays an important role in the soil P cycle. It is present in various chemical forms, the relative amounts of which vary among soils, due to factors including climate, land use, and soil type. Few studies have investigated co-variation between P types or stoichiometric correlation with the key elemental components of organic matter– carbon (C) and nitrogen (N), both of which may influence P pool structure and dynamics in agricultural soils. In this study we determined the… 

The composition of organic phosphorus in soils of the Snowy Mountains region of south-eastern Australia

Few studies have considered the influence of climate on organic phosphorus (P) speciation in soils. We used sodium hydroxide–ethylenediaminetetra-acetic acid (NaOH–EDTA) soil extractions and solution

The chemical nature of organic phosphorus that accumulates in fertilized soils of a temperate pasture as determined by solution 31P NMR spectroscopy.

Inefficiency of fertilizer phosphorus (P) use in grazing systems is often associated with the accumulation of inorganic and organic P in fertilized soil. However, the chemical nature of the

Accessing Legacy Phosphorus in Soils

Repeated applications of phosphorus (P) fertilizers result in the buildup of P in soil (commonly known as legacy P), a large fraction of which is not immediately available for plant use. Long-term

Soil phosphorus pools with addition of fertiliser phosphorus in a long-term grazing experiment

Grasslands are a globally important use of land for food and fibre production, which often require the addition of phosphorus (P) fertiliser to maximise plant production. However, a large proportion

Phosphorus retention in constructed wetlands enhanced by zeolite‐ and clinopyroxene‐dominated lava sand

Constructed wetlands (CWs) are engineered systems for treating wastewater by sequestering nutrients and contaminants. Our aim was to assess the main phosphorus (P) binding states in operating CWs to

Understanding the forms and dynamics of soil phosphorus (P) is essential to maintain agricultural productivity while minimizing environmental risks. Since it was first used on soil extracts in 1980,



Organic phosphorus speciation and pedogenesis: analysis by solution 31P nuclear magnetic resonance spectroscopy

Changes in phosphorus (P) during soil development are central to the understanding of labile P for plant productivity and soil P management. We used NaOH‐EDTA extraction with 31P nuclear magnetic

Isolating the influence of pH on the amounts and forms of soil organic phosphorus

Soil pH influences the chemistry, dynamics and biological availability of phosphorus (P), but few studies have isolated the effect of pH from other soil properties. We studied phosphorus chemistry in

A quantitative assessment of phosphorus forms in some Australian soils

Solution 31P nuclear magnetic resonance (NMR) spectroscopy is the most common technique for the detailed characterisation of soil organic P, but is yet to be applied widely to Australian soils. We

Basic Edta as an Extractant for Soil Organic Phosphorus

Soil organic P is an important source of plant-available P in the Great Plains. It is, therefore, important in conservation tillage agriculture, that we know the size and the potential availability

A 31P nuclear magnetic resonance study of the phosphorus species in alkali extracts of soils from long‐term field experiments

SUMMARY The different forms of phosphorus (P) in 0.5 m sodium hydroxide extracts of soils from long-term field experiments at Rothamsted were characterized by 31P-nuclear magnetic resonance

Phosphorus Speciation and Sorption‐Desorption Characteristics in Heavily Manured Soils

Managing heavily manured soils for decreased P loss to waters requires improved understanding of the chemical and sorption-desorption characteristics of P in these soils. We used soils from
