Soil functions in Earth's critical zone- key results and conclusions
Original language description
This paper summarizes conclusions of the SoilTrEC Project for a network of European, Chinese, and USA Critical Zone Observatories (CZOs). The study focused on the soil functions of biomass production, carbon (C) and water storage and transmission, water filtration, transformation of nutrients, and maintaining habitat and genetic diversity.The principal results demonstrate that soil functions can be quantified as biophysical flows and transformations of material and energy. A new dynamic model for soil structure development and data sets from the CZOs, demonstrate both seasonal fluctuations in soil structure dynamics related to vegetation dynamics and soil C inputs, and long-term trends in soil C storage and soil structure development. Cross-site comparison for twenty soil profiles at seven field sites with variation in soil type, lithology, land cover, land use, and climate demonstrate that sites can be classified, using model parameter values for soil aggregation processes together with climatic conditions and soil physical properties, along a trajectory of soil structure development from incipient soil formation through productive land use to overly intensive land use with soil degradation.A new code (Integrated Critical Zone model) was applied with parameter sets developed from the CZO site data to simulate the biophysical flows and transformations that quantify soil functions. Process simulations coupled the new model for soil structure dynamics with existing modeling approaches for soil C dynamics, nutrient transformations, vegetation dynamics, hydrological flow and transport, and geochemical equilibria and mineral weathering reactions. Successful calibration, testing, and application of the model with data sets from manipulation experiments demonstrate the potential to apply modeling and simulation to the scoping and design of new practices and policy options to enhance soil functions and reduce soil threats worldwide.
