Application of Potential Phosphate-Solubilizing Bacteria and Organic Acids on Phosphate Solubilization from Phosphate Rock in Aerobic Rice
A study was conducted at Universiti Putra Malaysia to determine the effect of phosphate-solubilizing bacteria (PSB) and organic acids (oxalic & malic) on phosphate (P) solubilization from phosphate rock (PR) and growth of aerobic rice. Four rates of each organic acid (0, 10, 20, and 30 mM), and PSB strain (Bacillus sp.) were applied to aerobic rice. Total bacterial populations, amount of P solu...
متن کاملRole of phosphate solubilizing bacteria on rock phosphate solubility and growth of aerobic rice.
Use of phosphate-solubilizing bacteria (PSB) as inoculants has concurrently increased phosphorous uptake in plants and improved yields in several crop species. The ability of PSB to improve growth of aerobic rice (Oryza sativa L.) through enhanced phosphorus (P) uptake from Christmas island rock phosphate (RP) was studied in glasshouse experiments. Two isolated PSB strains; Bacillus spp. PSB9 a...
متن کاملIdentification of organic acids produced during rice straw decomposition and their role in rock phosphate solubilization
The production of organic acids and changes during decomposition of rice straw amended with tricalcium phosphate (TCP) and Udaipur rock phosphate (URP) were studied under laboratory conditions. The organic C content of rice straw decreased and total N increased with time, resulting in a decrease in C:N ratio as the decomposition progressed. The pH decreased to acidic range in all the treatments...
متن کاملisolation of phosphate solubilizing microorganisms from wheat rhizosphere and evaluation of the their solubilization potential at two insoluble phosphate sources
phosphorus (p) is one a nutrient elements for plant growth. in most soils has complex behavior and forms sparingly soluble compounds with soil particles. phosphorus bioavailability can be controlled by soil biological activities for optimum nutrition of plants. this study was carried out in order to isolation of p-solubilizing bacteria (psb) as well as p-solubilizing fungi (psf) and their scree...
متن کاملEffect of phosphate-solubilizing bacteria and oxalic acid on phosphate uptake from different P fractions and growth improvement of aerobic rice using
Using the isotope dilution P technique, a study was conducted to evaluate the P uptake and growth improvement of aerobic rice genotype (M9) inoculated with phosphate-solubilizing bacteria (PSB16, Bacillus sp.) and applied with Christmas Island Phosphate Rock (CIPR), and oxalic acid (OA). An absence of PSB and OA was considered as control treatment. The inoculation of PSB16 strain and OA applica...
