We sampled 40 sites consisting of ten major soil types at spring (wet) and late-summer (dry) seasons. The sample locations range from semi-arid to arid with an annual mean air temperature from 1.2 to 10.7 °C and annual precipitation from less than 200 to around 400 mm. Overall topsoil...
2006). Anthropogenic land degradation is typically initiated by changes in land management associated with the intensification of either agricultural orlivestock production. The human-inducedsoil degradationis often differentiated into degradation types (e.g.,soil erosion, nutrient decline, salinization) and...
These data are now being processed through the scanner and computer and will be included in the next report along with pictures of printout and imagery. Channel 7 appears to provide the most useful imagery related to soil differences. Soil types have been identified through the use of aircraft ...
