SummaryPlants that absorb nitrogen as NO3− tend to raise the pH in the rhizosphere. Those absorbing nitrogen as NH4+ or N2 lower the pH. The change in pH near the root surface may be calculated approximately from the H+ or HCO3− efflux and radius of the root; and the pH buffering capacity, moisture content, initial pH and pCO2 of the soil. An accurate equation, solved numerically, also takes account of root hairs, mass flow and slow acid-base reaction in the soil. The pH at the root surface… 
pH changes in the rhizosphere in relation to the pH-buffering of soils
TLDR
The low buffering capacity for soils of pH near 6 seems to be valid for a large number of soils with different properties.
Influence of root-induced pH on the solubility of soil aluminium in the rhizosphere
Increase in solubility of soil aluminium (Al) as a result of root-induced decrease of soil pH was studied. Soil samples of known distances from the roots of NH4-N fertilized Ryegrass were analyzed
Rhizosphere pH along different root zones of Douglas-fir (Pseudotsuga menziesii), as affected by source of nitrogen
Douglas-fir, grown on strongly acid soil (pH-H2O 3.87), was fertilized with ammonium, nitrate or ammonium nitrate as N-source. Rhizosphere pH along the root axis was measured with microelectrodes.
Origins of root-mediated pH changes in the rhizosphere and their responses to environmental constraints: A review
TLDR
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.
Mobilization of phosphate in different soils by ryegrass supplied with ammonium or nitrate
Mobilization of soil P as the result of plant-induced changes of soil pH in the vicinity of plant roots was studied. Seedlings of ryegrass were grown in small containers separating roots from soil by
Control of pH at the soil-root interface
A method to control the rhizosphere pH of plants under controlled nutritional conditions is suggested. An earlier developed method for plant growth in soilless culture according to the principle of
Root-induced modifications of the exchange of phosphate ion between soil solution and soil solid phase
TLDR
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.
A Model of Uranium Uptake by Plant Roots Allowing for Root-Induced Changes in the soil.
TLDR
A sensitivity analysis showed the importance of soil sorption and speciation parameters as influenced by pH and CO2 pressure; and of root geometry and root-induced acid-base changes linked to the form of nitrogen taken up by the root.
Fertilizer Potential of Struvite as Affected by Nitrogen Form in the Rhizosphere
Struvite is increasingly considered a promising alternative to mined phosphorus (P) fertilizer. However, its solubility is very low under neutral to alkaline pH while it increases with acidification.
Shaping the Other Sides: Exploring the Physical Architecture of Rhizosphere
The root system is immediately surrounded by a narrow zone of soil called the rhizosphere. A major proportion of biodiversity of the soil resides in the rhizosphere, hence accounting for the various

TLDR
The model predicts that a high population density will develop near the root surface, but the density will fall off steeply with increasing distance from the root, and further away the population reaches a peak and then declines.
