Light, water and healthy soil are three essential natural resources required for agricultural
productivity. Industrialization of agriculture has resulted in intensification of crop** …

The production of organic acids by fungi has profound implications for metal speciation,
physiology and biogeochemical cycles. Biosynthesis of oxalic acid from glucose occurs by …

Plant nutrients, with the exception of nitrogen, are ultimately derived from weathering of
primary minerals. Traditional theories about the role of ectomycorrhizal fungi in plant …

Land plants and their associated microbiota directly affect silicate mineral weathering in
several ways: by generation of chelating ligands, by modifying pH through production of CO …

Feldspars have the most intensely-studied dissolution kinetics of any of the silicate minerals.
This is partly because they are the most abundant silicate mineral in crustal rocks, and …

Mineralogy, microbial ecology, and mineral weathering in the subsurface are an intimately
linked biogeochemical system. Although bacteria have been implicated indirectly in the …

Microorganisms play an important role in the weathering of silicate minerals in many
subsurface environments, but an unanswered question is whether the mineral plays an …

The dissolution rate of apatite was determined in batch reactors in organic acid solutions
and in microbial cultures. Inoculum for the cultures was from biotite plus apatite crystals from …

This paper is centered on the specific effects of plants on the soil weathering environment;
we attempt to address how to quantify this component of the ecosystem and assess …

▪ Abstract The recycling of elements by plants and plant-induced biological activity cause the
rates and products of weathering to be markedly different from what would result in abiotic …
