Subject:
digital elevation models; kriging; prediction; soil; France
Abstract:
... Universal kriging with a topographic variable used as external drift was compared with ordinary kriging, ordinary kriging with external drift, and universal kriging for predicting the thickness of a superficial deposit on part of the Beauce of central France. Thickness was recorded at 62 sites and at another 25 sites to obtain a sample for validation. A Digital Elevation Model (DEM) was computed f ...

Abstract:
... The number of runoff and erosion studies in cultivated catchments in north west Europe is increasing. Measurements are usually costly and time‐consuming, in particular of soil hydrological properties because agriculture causes considerable spatial and temporal variation. A subdivision of the catchment is necessary to optimize the choice of sampling sites and to define extrapolation procedures. Fou ...

3. The Fractionnements des matières organiques: apport l'étude de la dynamique du carbone de sols cultivés et à sa modélisation

Subject:
acid hydrolysis; carbon; corn; fulvic acids; humic acids; labeling techniques; long term experiments; models; oxidation; prediction; soil
Abstract:
... Soil organic matter (SOM) dynamics are usually described by compartmental models. We have sought SOM separates that might be related to SOM dynamic compartments. The turnover of C in various separates from long–term field experiments with maize was measured using the natural 13C labelling technique. The Rothamsted carbon model gave a good prediction of the observed C turnover. Primary particle–siz ...
