Building Spatial Climate Model for Soil Capability Using Geomatics, West of Toshka, Egypt

Soil capability always related to soil quality, which directly affect productivity, environmental factors, land use/land cover, and bio-activities. Monitoring of soil capability parameters will help to simplify and explain some impacts of climate effect on hyper arid condition and the responses required for such difficult agricultural adaptation. This paper presented using geographic information system, GNSS and remote sensing techniques “geomatics” to manage and update soil spatial datasets, furthermore, spatial-climate monitoring for soil characteristics and distribution. Assessing land types and identifying degraded spots with soil problems such as salty, alkaline or other productive capability. Adding an interpolation methods for generalizing samples results for study area. In the current research, a spatial-climate model for soil capability was built to evaluate soil capability based on; chemical, physical and biological soil characteristics. The results of the spatial model were correlated with both land capabilities and climate of the study area. Nonetheless, this model proposed for decision-makers tool for soil capability classification under similar conditions.
