Differential Effect Of Coal Combustion Products On The Bioavailability Of Phosphorus Between Inorganic And Organic Nutrient Sources, Belaji Seshadri, Nanthi Bolan, Girish Choppala, Ravi Naidu

Dr Girish Choppala

In farming systems, all the applied phosphorus (P) is not available to plants because they are either adsorbed in soil or lost to the environment through leaching or runoff. The effect of coal combustion products (CCPs) for enhancing the bioavailability of applied phosphorus (P) in soil was examined separately for inorganic (KH₂PO₄ – PP) and organic (poultry manure – PM) P treatments, where fluidised bed combustion (FBC) ash emerged as the most effective amendment. Greenhouse study was conducted by growing mustard plants on FBC amended soils under leaching and non-leaching setups. The FBC increased the biomass yield …
