TL;DR: In this paper, the authors give an overview of those chemical processes that are directly induced by plant roots and which can affect the concentration of P in the soil solution and, ultimately, the bioavailability of soil inorganic P to plants.

TL;DR: The aim of the present review is to define the various origins of root-mediated changes of pH in the rhizosphere, i.e., the volume of soil around roots that is influenced by root activities and the response of plant roots to deficiencies of P and Fe and to Al toxicity.

TL;DR: It is shown that limited phosphorus and nitrogen availability are likely to jointly reduce future carbon storage by natural ecosystems during this century and if phosphorus fertilizers cannot be made increasingly accessible, the crop yields projections of the Millennium Ecosystem Assessment imply an increase of the nutrient deficit in developing regions.

TL;DR: This review considers the unique biophysical and biogeochemical properties of the rhizosphere and draws some connections between them, and addresses the various mechanisms by which roots and associated microorganisms alter these major drivers of soil biogeochemistry.

TL;DR: It is shown that rhizosphere processes in the long run are central to biogeochemical cycles, soil formation and Earth history, and major anticipated discoveries will enhance basic understanding and allow applications of new knowledge to deal with nutrient deficiencies, pests and diseases.
