Bioavailability of soil inorganic P in the rhizosphere as affected by root-induced chemical changes: a review

In most soils, inorganic phosphorus occurs at fairly low concentrations in the soil solution whilst a large proportion of it is more or less strongly held by diverse soil minerals. Phosphate ions can indeed be adsorbed onto positively charged minerals such as Fe and Al oxides. Phosphate (P) ions can also form a range of minerals in combination with metals such as Ca, Fe and Al. These adsorption/desorption and precipitation/dissolution equilibria control the concentration of P in the soil…

Phosphorus saturation and pH differentially regulate the efficiency of organic acid anion-mediated P solubilization mechanisms in soil
Exudation of organic acid anions by plants as well as root-induced changes in rhizosphere pH can potentially improve phosphate (Pi) availability in the rhizosphere and are frequently found to occur
Bioavailability of Soil P for Plant Nutrition
The poor mobility of soil inorganic phosphorus is due to the large reactivity of phosphate ions with numerous chemical, mineralogical and biological soil constituents. Adsorption-desorption and
Competitive sorption reactions between phosphorus and organic matter in soil: a review
The incorporation of organic matter ( OM) in soils that are able to rapidly sorb applied phosphorus ( P) fertiliser reportedly increases P availability to plants. This effect has commonly been
Competitive and synergistic effects in pH dependent phosphate adsorption in soils: LCD modeling.
The calculation shows that adsorption is the major mechanism controlling phosphate solubility in soils, except at high pH in high P-loading soils where precipitation of calcium phosphate may take place.
Rhizosphere: A new frontier for soil biogeochemistry
Arsenate and phosphate adsorption in relation to oxides composition in soils: LCD modeling.
The results indicated that surface coating and substitution may have modified significantly oxyanion adsorption to Fe-oxides in soils, and how to account for this complexity is a challenge for geochemical modeling.
Competitive mobilization of phosphate and arsenate associated with goethite by root activity.
No mobilization of PV or As V was observed with the addition of higher amounts of goethite, probably because of decreasing competition between organic anions, PV, and As V for binding sites.
The influence of the wheat rhizosphere on phosphorus desorption kinetics in calcareous soils amended with municipal sewage sludge
Plant growth in arid environments is limited by phosphorus (P) availability because of the low concentration of P in the soil solution. In addition, soil processes in the rhizosphere affect the
Precipitation, adsorption and rhizosphere effect: The mechanisms for Phosphate-induced Pb immobilization in soils-A review.
Three principal mechanisms may be responsible for P-induced Pb immobilization, including direct precipitation, ion-exchange (or substitution) effect and liming effect, and the adsorption of Pb are discussed.


Root-induced modifications of the exchange of phosphate ion between soil solution and soil solid phase
The kinetics of the PO4 exchange between liquid and solid phases of soil were significantly different between rhizosphere and bulk soils, however, the resulting changes in the ability of the soil solid phase to replenish solution PO4 were almost fully explained by the depletion of soil solution P.
Dynamics of phosphorus in the rhizosphere of maize and rape grown on synthetic, phosphated calcite and goethite
Whether H+ or OH− release can induce the mobilization of P in the rhizosphere of maize and rape supplied with NO3-N or NH4-N and grown on synthetic phosphated calcite or goethite as sole source of P is tested.
Effect of pH and some organic anions on the solubility of soil phosphate: implications for P bioavailability
Summary The effect of pH and the addition of carboxylates (acetate, oxalate, tartrate, salicylate and citrate) on the solubility of soil phosphate has been investigated to assess the possible
Dissolution of phosphate rock in the rhizosphere of five plant species grown in an acid, P-fixing mineral substrate
Abstract The dissolution of phosphate rock (PR) was studied in the presence and absence of plants grown in an acid mineral substrate (alumina sand) that simulates an acidic, P-fixing soil. This

Rhizosphere processes strongly influence the availability of phosphorus (P) to plants. Organic ligands that are exuded from the root surface mobilize phosphorus by dissolution of P minerals or by
