“…Our results did not confirm the hypothesis that oilseed rape would use HCl-P i (Ca-bound P) because of its ability to acidify the rhizosphere as found by Hoffland et al (1989). This contradicting result may be related to that Hoffland et al (1989) had used a sand culture which has no pH buffer capacity while in the soils used in the present experiment, and more so in the Eutric Fluvisol, the buffering of the soil pH may have resulted in only small pH changes in the rhizosphere which were not sufficient to solubilise HCl-P i.…”

“…Thus, we expected that the maize plants in our experiment would also have increased their P mobilizing capability when becoming older and therefore accessing P fractions in the rhizosphere younger plants were unable to. In oilseed rape the P deficiency may have induced an exudation of organic acids (Hoffland et al, 1989) causing a strong depletion of Ca-bound P in the rhizosphere.…”

“…Therefore, P mobilization strategies of plants may be effective in one soil but not in another of different pH controlling P bonding. We furthermore hypothesize that plants that acidify the rhizosphere, such as oilseed rape (Hoffland et al, 1989), will be more effective than maize in depleting acid soluble P in the rhizosphere of neutral to alkaline soils.…”

In alkaline soils, where most of the P is acid soluble, we hypothesize that species that acidify the rhizosphere such as oilseed rape, are more efficient to use soil P than for example maize. In field experiments, adult maize plants extracted more P per unit of root than young plants. Here we hypothesize that older plants access P fractions that younger plants were not able to. Thus, the aim of this research was to study the P fractions used by maize and oilseed rape growing in an acid sandy and a neutral loamy soil and how plant age might affect it. A special pot system was developed in which P uptake by the plants came from roots that grew freely in soil. To obtain rhizosphere soil, a portion of the roots was concentrated to form a root mat on a planar soil surface covered by a fine nylon mesh. Cutting the soil on the other side of the mesh into slices gave rhizosphere soil at different distances from the root surface. We examined the P fractions used by maize and oilseed rape at three growth stages by measuring the depletion of three inorganic (P i ) and two organic (P o ) P fractions in the rhizosphere. Oilseed rape did not affect the P o fractions in any of the two soils, and maize only in the acid soil. Both species in both soils depleted only the alkali soluble P i fraction. The degree of depletion was between 12-26 %. The acid soluble P i was not depleted by neither oilseed rape nor maize. Plant age had no effect on P fraction depleted or on the degree of depletion.

“…[3][4][5][6][7][8] Induction of organic anions efflux was also reported in P-deficient rape, 9 white lupin 10 and alfalfa. 11 However, in our previous investigation we did not observe any induction of organic anion efflux under P-deficient condition, 12 but we have shown that Al-induced efflux is more pronounced in P-sufficient plants of rape.…”
