In calcareous soils, phosphorus (P) availability to plant is impaired due to the formation of insoluble complexes with calcium and magnesium. Therefore, this study was executed to compare the P use efficiency (PUE) of four different P sources [rock phosphate (RP), acidulated rock phosphate (ARP), single super phosphate (SSP) and di ammonium phosphate (DAP)] alone or pre-treated with organic amendments (farm yard manure (FYM) enriched compost, simple compost and humic acid (HA)) along with control in maize crop under calcareous soils. All treatments irrespective of P sources received 90 kg P2O5 ha−1. Phosphorus application regardless of its sources and combination with organic amendments significantly improved maize growth, yield as well as P uptake and PUE. Rock phosphate when applied alone was recorded inferior but its performance significantly improved with compost or its pre-addition with FYM and HA, that further enhanced upon acidulation. Maize grain yield increased by 21, 22.2, 67.9 and 94% with RP, ARP, ARP enriched compost and ARP+ compost respectively, over control. Similarly, PUE of DAP improved from 31.7 to 43.1 and 39 with sample and enriched compost correspondingly. Post-harvest soil and grain P were at par for SSP, ARP and DAP alone or in conjugation with organic amendments when averaged across the amendments. These results suggested that pretreatment of P sources with organic amendments is an economical and more feasible approach to improve maize yield and PUE. Moreover, on-farm acidulation of RP may give at par results with SSP and DAP with cheaper rate and hence recommended for P management in maize in alkaline calcareous soils.

The low availability of phosphorus (P) in the soil drastically limits the world productivity of crops such as cotton. In order to contribute sustainably to the solution of this problem, the current study aimed to evaluate the capacity of phosphate-solubilising bacteria to improve plant growth and its relationship with physiological parameters, as well as the shoot P content in cotton plants in a soil with low P availability amended with rock phosphate. The results showed that, of the six plant growth-promoting bacteria strains evaluated under greenhouse conditions, the Rhizobium strain B02 significantly promoted growth, shoot P content and photosynthetic rate. This strain also improved the transpiration rate and the relative content of chlorophyll but without significant differences. Remarkably, Rhizobium sp. B02 had a more significant effect on plant growth compared to the P nutrition. Furthermore, the effect of its inoculation was more pronounced on the roots' growth compared to the shoot. Finally, application of Rhizobium strain B02 showed the capacity to optimize the use of low-solubility fertilizer as the rock phosphate. These findings could be associated with the metabolic activities of plant growth promotion exhibited by phosphate-solubilising strains, such as phosphate solubilisation, production of indole compounds and siderophores synthesis. In conclusion, this research provides evidence of the biotechnological potential of the Rhizobium genus as phosphate-solubilising bacteria with multiple plant growth-promoting activities capable of improving the plant growth and phosphate nutrition of non-leguminous crops such as cotton in soil with low P availability amended with rock phosphate.

The variation in physical and chemical properties of calcareous soils in Jordan valley has been changed dramatically due to use large amount of fertilizers in regular manner. Addition of organic acid such as citric acid (CA), can greatly change the pH which can affects plant growth and production, the weakly ionized organic acid present in the calcareous soil mostly in the form of organic matter, can play major rule in soils to raise the availability of mineral nutrients that are essential for crops, by lowering soil density, reducing soil salinity and the effects of suspended particles in soil which may hinder plant growth. The reduction in the pH of the soil enhance the availability of nutrients such as Fe, Cu, Zn, ions, by converting the metallic insoluble state to ionic form, and thus nutrients are easily available for plants intake, the salinity of the soil did not change by increasing the citric acid concentration, while the pH of the soil decreases. Data are presented to show the effects of citric acid (CA) concentration, ionic concentration of iron, copper, Zinc and manganese and the decrease in soil PH and soil density.

P Fertilizers

In calcareous soil, the significant portion of applied phosphorus (P) fertilizers is adsorbed on the calcite surface and becomes unavailable to plants. Addition of organic amendments with chemical fertilizers can be helpful in releasing the absorbed nutrients from these surfaces. To check out this problem, a field experiment was conducted for two years to determine the effect of P fertilizers and humic acid (HA) in enhancing P availability in soil and their ultimate effect on growth, yield and P uptake of wheat in calcareous soils. The experiment was comprised of five levels of P (0, 45, 67.5, 90 and 112.5 kg P2O5 ha−1) as a single superphosphate (SSP) and 2 levels of locally produced humic acid (with and without HA) arranged in a two factorial randomized complete block design (RCBD) with three replications. Wheat plant height, spike length, number of grains per spike, 1000-grain weight, grain, straw and biological yield were significantly improved by the addition of HA with SSP. Very often, the performance of 67.5 kg P2O5 ha−1 with HA were either similar or better than 90 or even 112.5 kg P2O5 ha−1 applied without HA. Post-harvest soil organic matter, AB-DTPA extractable and water-soluble P, plant P concentration and its uptake were also significantly improved by the addition of HA with SSP compared to sole SSP application. It was evident that P efficiency could be increased with HA addition and it has the potential to improve crop yield and plants P uptake in calcareous soils.

Sandy soil has limitations factor in supporting plant growth such as low soil organic carbon (SOC), cation exchange capacity (CEC), macro-micro nutrient content, water retention capacity, and high permeability rate. To improve soil conditions, it can be done by adding mycorrhizae and soil amendments. This study aimed to determine the effect of mycorrhizae application and soil amendments on the P availability and P uptake of plants in sandy soil. The research was conducted in a greenhouse of Agricultural Faculty, Sebelas Maret University. Used a completely randomized design consisting of 2 factors. The first factor was mycorrhizae with 2 levels, namely without mycorrhizae (M0) and mycorrhizae with 6 spores/plants (M1). The second factor was soil amendments; without amendment (P0), cow manure 60 tons/ha (P1), rock phosphate 150 kg/ha (P2), and combination of cow manure 60 tons/ha and rock phosphate 150 kg/ha (P3). The results showed that the application of mycorrhizae and soil amendments significantly increased available P, SOC, CEC, P concentration, and P uptake. Interaction of mycorrhizae 6 spores/plant and rock phosphate 150 kg/ha was able to increase the availability of soil P up to 12.8 times, plant tissue P concentration up to 1.4 times, and P uptake up to 2.27 times compared to the control. Application of mycorrhizae 6 spores/plant and cow manure of 60 tons/ha gave the best results on SOC and mycorrhizae with a combination of cow manure and rock phosphate gave the best results on CEC.

A sand-culture experiment was carried out in a growth chamber to investigate the phosphorus (P) efficiencies of 8 barley cultivars that are parents of 4 mapping populations, and the effects of P nutrition on plant uptake of zinc (Zn), copper (Cu), and manganese (Mn). Two sources of phosphate were used, rock phosphate (sparingly soluble) and CaHPO4 (readily available). There were significant differences in P uptake and utilisation efficiencies between the 8 cultivars. Among the cultivars, the Sahara–Clipper pair is of the most interest, because these 2 cultivars had large differences in root/shoot ratios, P allocation between root and shoot, and P uptake/utilisation efficiencies. Higher P availability significantly reduced plant Zn uptake and tissue concentrations in all cultivars. Shoot Zn concentrations were found to decrease significantly with P influx to the xylem (P < 0.01), indicating that genotypic variations in P translocation from roots to shoots may interact with Zn accumulation in shoots. Higher P availability reduced Cu concentrations in shoots, probably due to a dilution effect. P availability (rock phosphate v. CaHPO4) seemed to affect plant uptake of Mn in some cultivars, but further study is needed to elucidate the mechanisms involved and the practical implications of this interaction in Mn-deficient soils.

The effect of phosphorus solubilizing bacteria Bacillus polymyxa and AM-mycorrhizal fungi Rhizophagus fasciculatus with and without rock phosphate treatments on growth of Terminalia paniculata and T. tomentosa were studied in nursery. The results showed that the combined inoculation of both PSB, AM fungi and rock phosphate produced vigorous plant growth of tree seedlings for quick planting. The experiments clearly demonstrated that the combined inoculation of PSB and AM fungi brought marked increase in plant growth, dry matter, and P uptake when, compared to individual inoculants or non-inoculated plants. The increase in growth was attributed to the increase in P uptake in shoots of the seedlings. The results indicated that both organisms have synergistic effect with additional 250 mg RP/kg rock phosphate treatment for T.paniculata Roth. and 150 mgRP/kg for T.tomentosa W.& A. in green house conditions.
