There is a spatial variation of C, N, O and H stable isotope ratios in different substrates in nature. This spatial variation can be analyzed using isotope spatial models and presented in maps (isotope + landscape = isoscape). We use geostatistical methods to create continuous surfaces with isotope values from different materials. We sought to elaborate regional isoscapes to improve the comprehension of soil organic matter dynamics in the Neotropics, and to the assignment of material with unknown origin using multi-isotope spatial models.
