摘要: Nitrogen mineralization kinetics of Costa Rican soils developed from volcanic ash were investigated. Two aspects the aerobic incubation method proposed by Stanford and Smith (1972) examined: addition of—N nutrient leaching solution, air-drying samples prior to incubation. Net cumulative N mineralized over 210 days was analyzed in terms three kinetic models mineralization: single term, first-order (FO); two (DFO); combined first-order, zero-order (FOZ).
