Report on a) soil quality status of trial sites, b) interactions between climate, topography and agricultural systems on indicators of soil quality, and c) evaluation of the best subset of measurements for (aggregate) indicators of soil quality.

Report on a) current soil quality status of long-term trial sites, b) interactions between pedo-climatic zone, topography and crop(/livestock) systems on indicators of soil quality, and c) evaluation of the best subset of measurements that could be used to develop (aggregate) indicators of agricultural soil quality for desired ecosystem services.
