Phosphorus-31 nuclear magnetic resonance spectral assignments of phosphorus compounds in soil NaOH–EDTA extracts
Soil P composition can be conveniently determined in alkaline extracts using solution 31P nuclear magnetic resonance (NMR) spectroscopy, but spectral assignments are based on fragmentary literatureExpand
Inositol phosphates in the environment.
Recent advances in technology, such as the development of suitable chromatographic and capillary electrophoresis separation techniques, should help to elucidate some of the more pertinent questions regarding inositol phosphates in the natural environment. Expand
Drought sensitivity shapes species distribution patterns in tropical forests
It is shown that differential drought sensitivity shapes plant distributions in tropical forests at both regional and local scales, and changes in soil moisture availability caused by global climate change and forest fragmentation are likely to alter tropical species distributions, community composition and diversity.

Optimizing phosphorus characterization in animal manures by solution phosphorus-31 nuclear magnetic resonance spectroscopy.
Improvements in spectral resolution of more concentrated NaOH extracts were compromised by the disappearance of phospholipids and inorganic polyphosphates, notably in swine and cattle manure extracts, which indicated either degradation or a change in solubility. Expand
Extraction of soil organic phosphorus.
This work critically review the extraction of soil organic phosphorus, including procedures for quantification, speciation, and assessment of biological availability, including a single-step procedure involving sodium hydroxide and EDTA. Expand
The phosphorus composition of temperate pasture soils determined by NaOH-EDTA extraction and solution 31P NMR spectroscopy
Information on the composition and dynamics of soil phosphorus (P) remains limited, but is integral to understanding soil biogeochemical cycles. We used solution 31P nuclear magnetic resonance (NMR)Expand
Mycorrhiza-mediated competition between plants and decomposers drives soil carbon storage
This finding links the functional traits of mycorrhizal fungi to carbon storage at ecosystem-to-global scales, suggesting that plant–decomposer competition for nutrients exerts a fundamental control over the terrestrial carbon cycle. Expand
Phosphorus compounds in sequential extracts of animal manures: chemical speciation and a novel fractionation procedure.
A simplified two-step fractionation procedure involving extraction of readily soluble phosphorus in 0.5 M NaHCO3 followed by extraction of stable phosphorus in a solution containing 0. Expand
Resource partitioning for soil phosphorus: a hypothesis
A conceptual model of resource partitioning for soil phosphorus is proposed, which describes a hypothetical example of four coexisting plant species that differ in their ability to access soil organic phosphorus compounds, which are grouped to form a gradient of biological availability based on the processes involved in their utilization by plants.
