Remote Sensing GIS and Space Applications


The gaps in knowledge and existing challenges in assessing soil quality within different land use-cover types : Milestones and challenges in the soil quality estimation methods at different spatial scales , Provides the status of soil quality assessment within different parts of the world , Suggests future researchable areas in soil quality, using remote sensing and GIS technology.

Precise soil quality assessment is critical for designing sustainable agriculture policies, restoring degraded soils, carbon (C) modeling, and improving environmental quality. Although the consequences of soil quality reduction are generally recognized, the spatial extent of soil degradation is difficult to determine, because no universal equation or soil quality prediction model exists that fits all ecoregions. Therefore it is possible that drastic changes in soil quality may be occurring in sites which are not identifiable on existing maps. Soil quality can either be directly inferred from SOC concentration, or through the assessment of the soil physical, chemical and biologic properties.
