“…The treatment combinations are given below. The treatments used for the pot trial were T1; control (normal soil), T2; ERP (soil + ERP), T3; TCP (soil + TCP), T4; ERP + biofertilizer (soil + ERP + biofertilizer), T5; TCP + biofertilizer (soil + TCP + biofertilizer); and T6; biofertilizer (soil + biofertilizer) ( Table 1 ) [ 36 ].…”

As phosphorus (P) bioavailability is limited in arable lands, chemical fertilizers are being used by farmers to increase crop production. Phosphate-solubilizing microorganisms (PSMs) increase the bioavailability of sparingly soluble inorganic and organic soil phosphorus. Therefore, the current study was an effort to evaluate the phosphate-solubilizing efficiency of PSMs using tricalcium phosphate (TCP) and Eppawala rock phosphate (ERP). The efficiency of phosphate solubilization by a series of identified isolates was compared using TCP (5 g L−1) and ERP (5 g L−1) as a P source in Pikovskava’s broth. Twelve microbial isolates that showed a higher efficiency in phosphate solubilization were selected for the production of the biofertilizer. The isolate F10 in ERP broth was characterized by the highest significant level of available phosphorus (896.98 ± 10.41) mg L−1, followed by F5 (Aspergillus sp.) in TCP broth 991.43 ± 1.37 mg L−1. A pot trial was carried out by using Capsicum annuum L. as the test plant in two soil conditions: sterilized soil and non-sterilized soil with six treatments and four replicates. The significantly highest plant height, leaf length, and width were shown by chili plants treated with the formulated biofertilizer. Therefore, the application of native PSMs appeared to be an efficient method of solubilizing sparingly soluble P compounds into plant-available forms.

Non-nutritive metals, especially cadmium (Cd), are present in P fertilizers; the long-term application of these P fertilizers leads to Cd build-up in the soil. The current study aims to evaluate the impacts of P sources and rates on the growth of maize (Zea mays L.) and the bioavailability of Cd. Twelve treatments including rock phosphate 4 g kg−1 (RP1); 8 g kg−1 (RP2); 12 g kg−1 (RP3)); single super phosphate 333 mg kg−1 (SSP1); 444 mg kg−1 (SSP2); 555 mg kg−1 (SSP3); di-ammonium phosphate 130 mg kg−1 (DAP1); 174 mg kg−1 (DAP2); 218 mg kg−1 (DAP3); mono-ammonium phosphate 115 mg kg−1 (MAP1); 154 mg kg−1 (MAP2); 193 mg kg−1 (MAP3) in two soil textures (sandy and clayey) were assessed. Results revealed that all P sources significantly influenced the plant growth and yield characteristics of maize (p ≤ 0.05). In both soil textures, P in soil and plant, plant growth and yield characteristics were maximized by MAP and DAP. Cadmium build-up in soil and uptake was also significantly (p ≤ 0.05) affected by P sources, levels, and soil texture. It was observed that Cd build-up in soil and uptake by plants boosted with increasing P levels. Maximum Cd concentration in plant root and shoot was found with SSP3, and its concentration in soil increased with MAP3, whereas the concentration was higher in sandy texture. The study concludes that type of P fertilizer should be determined based on texture and human consumption of the crop to avoid Cd toxicity.
