“…It has been shown that the total Zn content in shoots was higher in mycorrhizal than non-mycorrhizal plants grown in soils with low P (Kothari et al, 1991a,b;Heggo & Barakah, 1994;Liu et al, 2000;Ortas, 2003). Similar results were also reported for wheat grown in calcareous soil (Goh et al, 1997).…”

Since most of the Central Anatolian soils are P and Zn deficient, mycorrhizae may help plants to obtain sufficient nutrients from the soil without the need to apply additional chemical fertilizers. As far as is known, some plants are strongly mycorrhizal dependent for P nutrition, but less is known about the mycorrhizal dependence with Zn nutrition. Hypotheses were tested under P and Zn deficient soils to find out whether kidney bean plants are mycorrhizal dependent or not. Kidney bean (Phaseolus vulgaris L.) plants were grown for 8 weeks in two widely distributed calcareous clay soils with low nutrient content from Central Anatolian Sultanö nü and Konya soils (sterilized by autoclaving). The experiment was conducted with three levels of phosphorus (0, 25, 125 mg P kg (1 soil), and two rates of Zn (0 and 5 mg Zn kg (1 soil) Two selected arbuscular mycorrhizal (AM) species (Glomus mosseae and G. etunicatum) were inoculated. In the Sultanö nü soil, mycorrhizal inoculation increased plant growth and P and Zn uptake. The positive effect of mycorrhizal inoculation on plant P content and uptake was found to be higher when higher levels of phosphorus were applied. The soil from Konya with a high concentration of boron inhibited normal growth of kidney bean plants. Mycorrhizal root colonization was different with mycorrhizal inoculation. Root colonization was not affected by P and Zn application, but it has been shown that the plant is strongly dependent on P nutrition, especially at low P application levels. However, although mycorrhizal inoculation increased plant concentration of Zn, plants were less dependent on Zn nutrition.

“…In the current study, soil DTPA-Zn and DTPA-Cu were not decreased by P application (Fig. 6B), indicating that the current P supply did not affect Zn and Cu solubility in soil but may have affected Zn and Cu uptake at the root surface or movement through the plant after uptake (Goh et al, 1997). Another possible explanation is that P application often reduces the colonization of roots by arbuscular mycorrhizal fungi (AMF) (Ova et al, 2015).…”

Decreased micronutrient concentration in cereal grains caused by excessive application of phosphorus (P) fertilizer may contribute to reduce their nutritional quality. To help correct this problem in maize grain, a 3-year field experiment was conducted to determine how P application rate affects micronutrient partitioning in maize shoots and other plant organs and micronutrient bioavailability in grain. Phosphorus application significantly decreased shoot zinc (Zn) and copper (Cu) concentrations at all growth stages but had no effects on shoot iron (Fe) and manganese (Mn) concentrations. As the P application rate increased, shoot Zn and Cu contents decreased, and shoot Fe and Mn contents increased. The ratios of pre-anthesis to post-anthesis mineral contents were not affected by P application rate except Zn. P application increased the percentage of Zn that was allocated to grain and decreased the percentage that was allocated to other tissues, but had no effects on the allocation of other micronutrients among tissues. The bioavailability of Zn, Cu, Fe, and Mn in grain decreased as P application rate increased. Overall, taking account of grain yield and nutrients concentration, P fertilizer rates should range from 12.5 to 25.0 kg P ha −1 under the local condition. It can be concluded that not only grain yields, but also nutritional quality, should be considered in assessing optimal P rates in maize.

“…Phosphorus uptake in basin wildrye plants significantly increased with P availability (Table 1), with up to four times the P accumulation in the high compared with the low P treatments (Table 2) Shoot P concentrations were higher than those found in the roots with minimal As application; a shift in root to shoot P ratios occurred with increased As availability and the subsequent interactions of As and P. Mean shoot biomass of the plants generally failed to increase with higher P availability, in contrast to that seen in grasses such as big bluestem ( Andropogon gerardii Vitman) (Hetrick et al, 1986), perennial ryegrass ( Lolium perenne L.) (Baligar et al, 1997), and wheat ( Triticum aestivum L.) (Goh et al, 1997).…”

Revegetation of arsenic (As)-rich mine spoils is often impeded by the lack of plant species tolerant of high As concentrations and low nutrient availability. Basin wildrye [Leymus cinereus (Scribner & Merr.) A. Löve] has been observed to establish naturally in soils with elevated As content and thus may be useful for the stabilization of As-contaminated soils. An experiment was conducted to evaluate how variable phosphorus (P) concentrations and inoculation with site-specific arbuscular mycorrhizal fungi influence As tolerance of basin wildrye. Basin wildrye was grown in sterile sand in the greenhouse for 16 weeks. Pots of sterile sand were amended to create one of four rates of As (0, 3, 15, or 50 mg As kg(-1)), two rates of P (3 or 15 mg P kg(-1)), and +/-mycorrhizal inoculation in a 2 x 4 x 2 factorial arrangement. After 16 weeks of growth, plants were harvested, shoots and roots thoroughly washed, and the tissue analyzed for total shoot biomass, total root and shoot As and P concentrations, and degree of mycorrhizal infection. Basin wildrye was found to be tolerant of high As concentrations allowing for vigorous plant growth at application levels of 3 or 15 mg As kg(-1). Arsenic was sequestered in the roots, with 30 to 50 times more As in the roots than shoots under low P conditions. Mycorrhizal infection did not confer As tolerance in basin wildrye nor did mycorrhizal fungi influence biomass production. Phosphorus concentrations of 15 mg kg(-1) effectively inhibited As accumulation in basin wildrye. Basin wildrye has the potential to be used for stabilization of As-rich soils while minimizing exposure to grazing animals following reclamation.
