Electron transfer (redox) reactions, mediated by soil microbiota, modulate elemental cycling
and, in part, establish the redox poise of soil systems. Understanding soil redox processes …

Despite ongoing management efforts, phosphorus (P) loading from agricultural landscapes
continues to impair water quality. Wastewater treatment research has enhanced our …

Soil phosphatase levels strongly control the biotic pathways of phosphorus (P), an essential
element for life, which is often limiting in terrestrial ecosystems. We investigated the …

With the aim to explore the possible role of mineral phosphate-solubilizing bacteria (PSB) in
phosphorus (P) cycling in iron-rich, acidic soils, we conducted a survey of PSB naturally …

Most studies concerning soil microorganisms and enzymes are focused on the upper
horizons of the soil profile even though they transform soil organic matter at every depth of …

Background Soil phosphorus (P) availability can be an important regulator of ecosystem
processes. Changes in P availability over time have long been studied, but the P …

Legume trees form an abundant and functionally important component of tropical forests
worldwide with N2-fixing symbioses linked to enhanced growth and recruitment in early …

Most phosphorus (P) in soils is unavailable for direct biological uptake, as it is locked within
primary or secondary mineral particles, adsorbed to mineral surfaces, or immobilized inside …

Relationships between tropical rain forest biomass and environmental factors have been
determined at regional scales, eg the Amazon Basin, but the reasons for the high variability …

Microbial activity within the soil is critical for plant growth and development, and a major
determinant of crop performance and yield. Claypan soils are characterized by a dense …
