Litter and compost were obtained at a cowshed of a livestock farm in Andong city in Korea. Themorphological change of nitrogen and phosphorous from these samples were examined and suggesteda more useful and realistic way for reducing them. Constituents and their content of sample wereidentified by XRF. The nitrite ion (NO2−), nitrate ion (NO2−) and phosphate ion (PO43−) and ammoniumion (NH4+), total phosphorous (T-P) and total nitrogen (T-N) released from sample were analyzedusing ion chromatograph and UV/Vis spectrometry. As the results of this study, the ammonia in theearly stage of cow excretion is a need to make an ammonia gas state that can be immediately volatileby increasing the pH. Nitrogen and phosphorous, the main source of nutrition in green algal bloomcan be reduced by transforming insoluble salts such as calcium phosphate (CaHPO4·3H2O) and struvite(NH4MgPO4·6H2O), respectively, with addition of Ca and Mg after stimulating fermentation of compost.
