Soil degradation is defined as a decrease in soil quality, which is caused by non sustainable soil management. When the soil is losing its functionality is directly related with decreasing soil quality. This PhD proposes a scheme of intrinsic soil indicators for determining soil quality. This scheme includes three different sets of soil quality indicators derived from basic soil use criteria. Such criteria is based upon indicator availability, suitability and usefulness. These indicators are grouped according to three different soil threats; declining organic matter, desertification and soil salinity. These indicators were chosen under a European framework (COM (2002) 179 final) and by natural processes. With respect to this framework, these indicators should be interpretable in the context of soil quality, whilst also providing an auditable pathway through which soil management decisions can be made. The methods selected showed helpful results determining soil quality being well selected for the use of soil indicators. EM measurements provide relevant information on within-field variability of soil salinity. SOC distribution is important to be calculated in space and in depth. The MEDALUS and RUSLE models can assess the extent, intensity and severity of desertification processes in the target area.
