Summary

Remote sensing supported digital soil mapping has been proposed to improve soil surveying and to map the spatial variability of various soil properties over large regions. In this project we use satellite imagery, GIS and site-specific soil data to develop predictive models of soil biogeochemical properties in Water Conservation Area 2A. Digital soil modeling is used to produce soil maps of various taxonomic, morphological, and physico-chemical properties. The digital soil models are tested in an adjacent wetland (Water Conservation Area 3 North). Digital soil maps will be streamlined into NRCS databases to be disseminated.

Objectives

(1) Develop models to predict various types of soil properties: (i) soil taxonomic classes; (ii) soil morphological properties; and (iv) physico-chemical soil properties.

(2) Assess the usefulness to incorporate remote sensing imagery into soil prediction models.

(3) Develop a tutorial for remote-sensing supported digital soil mapping that enables transfer of the methods to other soil survey regions.
