Abstract/Contents:"Two incubation experiments, lasting 73 and 90 days, were conducted to evaluate the mineralization rate and release of carbon dioxide from soil samples treated with non-composted and composted spent coffee grounds (SCG). These samples were compared to each other as well as milorganite and urea, which are commonly used fertilizers. Destructively sampled microcosms were used to measure cumulative CO2. Soil organic C, total N, and plant available ammonium and nitrate concentrations of destructive samples were measured at regular intervals by the Keeney and Nelson (1982) method. Results from the SCG treatments in the 73-day incubation revealed: no difference between composted and non-composted; microbial respiration was greater than other treatments; inorganic N was immobilized until day 43; nitrate release was lower than the control until day 70; and Ammonium release occurred from 42 to 63 days. Based on these results, a 90-day incubation was conducted to fully understand the N release dynamics of SCG."
