AbstractThe within-field variability of soil mineral nitrogen (Nmin) in a grazed grassland of 8000m2 was examined. NO3-N concentrations were characterized by a high spatial variability. This can be explained by the uneven deposition of animal excreta. All NH4+-N as well as NO3-N values were lognormally distributed, before and after the grazing season. At the end of the grazing season the largest part...
