“…The general decrease in pH during the experiment could have arisen from a move back to equilibrium as well as due to an increase in microbial activity. Our results were in accordance with the previous observations of Aria et al (2010) and Khan and Sharif (2012), who reported a significant decrease in soil pH after applying PSB.…”

“…Reddy et al (2002) compared the efficiency of three isolates on the solubilization of RP and reported that all the isolates increased RP P release efficiency by solubilizing the tested RPs. Similar effects of bio-and organic fertilizers on RP availability and P fertilizer efficiency had also been reported in soils incubated for different incubation periods (Aria et al, 2010;Alzoubi and Gaibore, 2012). The mechanisms involved in the potential of PSB to solubilize P complexes or insoluble phosphates are well known and have been attributed to the processes of acidification, chelation, exchange reactions and the production of organic acids Ekin, 2010).…”

“…Among these, organic amendments, including animal manure, plant residues and green manure (Alloush, 2003;Toor, 2009;Aria et al, 2010;Adesanwo et al, 2012), composts (Nishanth and Biswas, 2008;Wickramatilake et al, 2010;Saleem et al, 2013), and bacterial inoculation (Panhwar et al, 2011;Gupta et al, 2011) are considered beneficial for improving the P efficiency. In addition, the combined application of water-soluble P fertilizers with RP is another option to increase the efficiency of RP P. Mashori et al (2013) used maize as a test crop in a pot experiment to examine the relative performance of RP, single superphosphate (SSP) and RP+SSP with and without farm yard manure (FYM).…”

Abstract. The ability of soil microorganisms and organic manure to convert insoluble phosphorus (P) to an accessible form offers a biological rescue system for improving P utilization efficiency in soil-plant systems. Our objective was to examine the P mineralization potential of two soluble P fertilizers (SPF), i.e., single superphosphate (SSP) and diammonium phosphate (DAP), and of insoluble rock phosphate (RP) with and without phosphate-solubilizing bacteria (PSB) and poultry manure (PM) and their subsequent effect on the growth, yield and P utilization efficiency (PUE) of chilli (Capsicum annuum L.). An incubation study was carried out on a loam (slightly alkaline) soil with 12 treatments: T 0 -control; T 1 -RP; T 2 -SSP; T 3 -DAP; T 4 -PM; T 5 -1/2 RP+1/2 SSP; T 6 -1/2 RP+1/2 DAP; T 7 -1/2 RP+1/2 PM; T 8 -RP+PSB; T 9 -1/2 RP+1/2 SSP+PSB; T 10 -1/2 RP+1/2 DAP+PSB; and T 11 -1/2 RP+1/2 PM+PSB. Phosphorus mineralization was measured by analyzing extractable P from the amended soil incubated under controlled conditions at 25 • C for periods of 0, 5, 15, 25, 35 and 60 days. A complementary greenhouse experiment was conducted in pots with chilli (Capsicum annuum L.) as a test crop. Growth, yield, P uptake and PUE of the chilli was determined during the study. Results indicated that P mineralization in soil amended with RP was 6.0-11.5 mg kg −1 , while both soluble P fertilizers resulted in 68-73 mg P kg −1 at day 0, which decreased by 79-82 % at the end of incubation. The integrated use of PSB and PM with RP in T 11 stimulated P mineralization by releasing a maximum of 25 mg P kg −1 that was maintained at high levels without any loss. Use of PSB decreased soil pH. In the greenhouse experiment, RP alone or RP+PSB did not have a significant impact on plant growth. However, the combined use of RP, PM and PSB in T 11 resulted in similar growth, yield and P uptake of chilli as DAP. The PUE of applied P varied from 4 to 29 % and was higher in the treatments that included PSB. We conclude that the use of PSB and PM with insoluble RP or with soluble P fertilizers could be a promising approach to enhance P availability from both low-grade RP and SPF for crop production in intensive cropping systems.

“…PRs are regarded as valuable alternatives for inorganic P fertilizers for a sustainable agriculture system (Jain et al, 2010), because they are cheaper sources of P (Vanlauwe and Giller, 2006). PRs have, however, low solubility (Aria et al, 2010). Solubility of phosphorus in the hard phosphate rocks may be increased by grinding, applying it low pH and P limiting soils, with the application of organics or by use of certain plant species (Aria et al, 2010;Kifuko et al, 2007).…”

Field experiments to evaluate effect of phosphorus (P) fertilizers and integration of legumes in sorghum cropping systems on soil pH, available nitrogen (N) and P, were conducted in Njoro Kenya during the short (SRS) and long rain seasons (LRS) of 2012 and LRS of 2013. The experiments comprised either lupin or chickpea grown with sorghum. The design was a split plot in a randomized complete block design. Main plots were cropping systems; sorghum monocrop, legume -sorghum rotation and legume-sorghum intercrop. Subplots comprised P sources (60 kg P ha -1 ); triple super phosphate (TSP) and minjingu phosphate rock (MPR). Application of TSP resulted in significantly higher nutrient concentrations in the soil than MPR addition in the first season. In the second and third seasons, the performance of MPRs approached that of TSP. Legume crops due to their release and accumulation of carboxylic acid lowered the pH to below 5.5 thus making solubilization of MPR and availability of P possible. Intercropping sorghum with lupin or chickpea with application of MPR gave comparable results with use of TSP. Since MPR is cheaper than TSP, growing lupin or chickpea in intercropping system with sorghum with application of MPR is recommended for improved chemical properties.

The benefits of bone char (BC) application may include both the mobilization of P for plant nutrition and immobilization of contaminant Cd in the soil. However, previous studies were conducted under equilibrium conditions that do not adequately reflect field conditions. Therefore, the objective was to study the effect of BC, surface-modified BC (BC plus ) and sulfur-enriched activated char (AC S ) application at different particle sizes on P-and Cd-mobilization under non-equilibrium conditions in a combined incubation-leaching experiment. Two soils each with the treatments (i) BC, (ii) BC plus , (iii) BC þ AC S , (iv) control (0 mg P kg À1 soil), and (v) AC S were leached five times during 70 days incubation. Over the complete incubation P-contents in leachates were significantly increased by BC and BC plus of 0.5-1 mm size. P-release from BCs was larger under non-equilibrium condition in this experiment compared with a previous continuous incubation experiment. AC s application reduced the P-release from BC of all particle sizes. The lowest leachate Cd-concentrations were found in soils amended with the smallest BC particles. Addition of BC plus and AC S significantly increased Cd leaching and the highest amounts of Cd were leached at the smallest particle size. In conclusion, the 0.5-1 mm size class of BCs performed best and should be introduced in practical agriculture using standard machinery.
