Comparison of carbon evolution rates between soils additives rates and incubation duration. Total inorganic N and NOs levels were considerably higher in the compost treatments than in the Fluff treatments indicating that decomposition of the Fluff resulted in significant N immobilization Table 6 . No changes in inorganic N concentration were observed in the Borrow Pit Fluff treatments through 90 d but the Dove Field Fluff treatments did increase slightly over time with an inverse relationship between rate and inorganic N concentration after 90 d of incubation. Ammonia levels did not differ at the same magnitude. Ammonia concentrations in the compost treatments remained very low and relatively constant across rates and soils but decreased slightly over time.
