Field Incubation Studies on Nutrient Mineralization of Bagasse on Spodosols and Histosols in Florida

The addition of organic byproducts to soils is a vital source essential nutrients for plant uptake. To reuse the effectively, there need estimate release patterns from byproducts. This study aimed investigate [nitrogen (N), phosphorus (P), and potassium (K)] bagasse, sugarcane milling byproduct, at two soil depths (surface 0 cm vs. buried 15 cm) in fallow fields on types (Histosols Spodosols) Florida. In addition, field incubation studies were conducted using mesh bag technique one year production. nutrient bagasse decomposition rates determined under each scenario. results indicated that decomposed faster when (totally after approximately 450 days) than placed surface (about 50% remained both Spodosols Histosols. Bagasse Histosols compared Spodosols. N P showed net immobilization month application buried, which additional fertilizers should be considered meet crop demand. K presented no immobilization, with rapid initial gradual
