Biogeochemical cycling bacteria as indices of pond fertilization:importance of CNP ratios of input fertilizers

摘要

Aims: The influence of carbon-nitrogen and nitrogen-phosphorus ratios of input fertilizers, and that of pond water, on the growth of heterotrophic and phosphate-solubilizing bacteria of water and sediment, was examined in relation to fertilizer mineralization indices using different modes of fertilization through inorganic and organic sources.
