Phosphorus is the second important key element after nitrogen as a mineral nutrient in terms
of quantitative plant requirement. Although abundant in soils, in both organic and inorganic …

Background Variation in microbial metabolism poses one of the greatest current
uncertainties in models of global carbon cycling, and is particularly poorly understood in …

Well-constrained carbon: nitrogen: phosphorus (C: N: P) ratios in planktonic biomass, and
their importance in advancing our understanding of biological processes and nutrient …

Phosphorus limitation on terrestrial plant growth is being incorporated into Earth system
models. The global pattern of terrestrial phosphorus limitation, however, remains unstudied …

Deforestation and land-use change in tropics have increased over the past decades, driven
by the demand for agricultural products. Although phosphorus (P) is one of the main limiting …

Non-mycorrhizal microbial inoculants (biofertilizers) can potentially stimulate soil P cycling
by solubilizing organic-and mineral-bound P. These P-solubilizing microorganisms (PSM) …

Introduction Sequential fractionation procedures have been an important tool in the study of
phosphorus (P) dynamics in soils and sediments for over 50 years. Throughout this period …

Abstract Silicon (Si), a quasi-essential element for plants, is abundant in the soil typically as
insoluble silicate forms. However, plants can uptake Si only in the soluble form of …

Phosphorus (P) availability is a limiting factor for plant growth in tropical and subtropical
regions, but many tropical and subtropical forests maintain high levels of productivity and …

Soil microorganisms regulate fundamental biochemical processes in plant litter
decomposition and soil organic matter (SOM) transformations. Understanding how microbial …
