| Résumé : |
The soil organic carbon (C) concentration of surface soil can be used in agricultural fields to vary crop production inputs. Soil organic C is often highly spatially variable, so that maps of soil organic carbon can be used to vary crop production inputs using precision farming technology. The objective of this research was to demonstrate the feasibility of mapping soil organic carbon on three fields, using remotely sensed images of the fields with a bare surface. Soil samples covering the range in soil organic carbon were taken from each field to develop a satisfactory relationship between soil organic carbon cotent and image reflectance values. The regression equations differed between fields, but gave highly significant relationship with R2 value of 0.93, 0.95, and 0.89 for the thr[...]

The regression equations differed between fields, but gave highly significant relationship with R2 value of 0.93, 0.95, and 0.89 for the three fields. Two classifications, arbitrarily classification and a minimum distance clustering, were applied in mapping soil organic carbon. A comparison of mapped soil organic |
