Though poultry litter is the main form of fertilizer applied to organic rice fields, it is difficlt to apply, has unpredictable nutrient availability and is limited in supply. Through this study it was shown that pelletized fertilizer has higher and more predictable Nitrogen availability and produced higher rice yields than poultry litter. Additionally, pelletized fertilizers had higher returns on investment, ranging from 57-76 percent, whereas poultry litter had returns of only 18-19 percent.
