Origins of root-mediated pH changes in the rhizosphere and their responses to environmental constraints: A review
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.Expand

Acid phosphatase role in chickpea/maize intercropping.
BACKGROUND AND AIMS Organic P comprises 30-80 % of the total P in most agricultural soils. It has been proven that chickpea facilitates P uptake from an organic P source by intercropped wheat. InExpand

Iron Deficiency-Induced Secretion of Phenolics Facilitates the Reutilization of Root Apoplastic Iron in Red Clover1
Phenolic compounds are frequently reported to be the main components of root exudates in response to iron (Fe) deficiency in Strategy I plants, but relatively little is known about their function.Expand

The role of iron in nodulation and nitrogen fixation in Lupinus angustifolius L
SUMMARY The effects of iron concentration in solution on nodulation and symbiotic N2 fixation in lupins (Lupinus angustifolius L. ev. Yandee) were studied in solution culture in the glasshouse byExpand

Changes in chemical and biological properties of a sodic clay subsoil with addition of organic amendments
An experiment was performed to examine the chemical and biological effects on high clay sodic subsoil following the incorporation and incubation with organic amendments. The main treatments consistedExpand

Calcium, magnesium and microelement uptake as affected by phosphorus sources and interspecific root interactions between wheat and chickpea
A glasshouse study was conducted to investigate the effect of supplying phytate and FePO4 and interspecific root interactions on the uptake of Ca, Mg, Fe, Mn and Zn by plants in a mixed culture ofExpand

Excess cation uptake, and extrusion of protons and organic acid anions by Lupinus albus under phosphorus deficiency.
In symbiotically-grown legumes, rhizosphere acidification may be caused by a high cation/anion uptake ratio and the excretion of organic acids, the relative importance of the two processes dependingExpand

Changes and availability of P fractions following 65 years of P application to a calcareous soil in a Mediterranean climate
The fate and availability of P derived from granular fertilisers in an alkaline Calcarosol soil were examined in a 65-year field trial in a semi-arid environment (annual rainfall 325 mm). SequentialExpand

pH above 6.0 reduces nodulation in Lupinus species
Lupinus angustifolius and Lupinus pilosus differ substantially in root growth in response to high solution pH with L. angustifolius showing much greater sensitivity to pH above 6. This study examinedExpand
