Abstract(s)
Knowledge of the amount of N mineralized from manure applied to soil and its availability to crops is extremely
important for precise fertilization practices and environment protection. The objectives of our study were to evaluate
the effect of cattle-slurry application rate on net N mineralization (NNM) and compare the field methods of soil core
incubation with acetylene (SIA) and the sequential in situ incubation of undisturbed soil cores (SIU) to assess N
mineralization in an intensive double-cropping forage system producing maize and Italian ryegrass (winter crop) for
silage.
