The Spatial Variability of Nitrogen-15 and its Relation to the Variability of Other Soil Properties1

F. Selles, R. E. Karamanos and R. G. Kachanoski2

ABSTRACT

The spatial variability of natural 15N abundance of a cultivated Chernozemic soil and its native prairie counterpart were smaller than that of total N, organic C, and the C/N ratio. Further, the number of samples required to estimate the true mean of total N with a given precision at various probability levels were twofold those required to determine the mean 15N abundance in both soils. The variability of organic C was > 10 times that observed for total N. The results of this study indicate that the spatial variability of the natural 15N abundance of total soil N in the surface horizons may reflect the isotopic composition of the nitrogenous substances entering the soil system or changes in the isotopic composition of soil N due to humification processes, probably induced by variations in topographic and microrelief features of the soil.
