Abstract

The growth of phosphate solubilizing bacteria (PSB) was examined in response to pond fertilization with poultry dropping (PD) (12,500 kg ha(-1) y(-1)), cattle manure (CM) (25,000 kg ha(-1) y(-1)), inorganic fertilizer (IF) consisting of urea (10.83 kg ha(-1) y(-1)) and single super phosphate (43.52kg ha(-1) y(-1)) and inorganic-organic mixed fertilizers (PD:CM:IF - 1:1:1) in simulated fish ponds under alluvial and laterite soil conditions as well as in natural ponds located in alluvial soil zone. The high correlation between dissolved oxygen and density of PSB implied the contribution of thelatter in the aerobic organic decomposition. The PSB were maximal in the PD, and minimal in the IF treatments. The distribution pattern of PSB was related to the autochthonous C/N ratio and the N/P ratios of water. Relatively low C/N ratios caused greater abundance of PSB. Increased fish productionin PD treatments was clearly due to increased primary productivity and higher zooplankton abundance resulting from nutrient-grazing-detritus-microbial-food chain complex pathways.
