Land use change is one of the main drivers of many processes of environmental change, as it influences basic resources of the landscape including the soil. Poor land management can rapidly deteriorate vast amounts of land, which frequently becomes a major threat to rural subsistence in many developing countries. Conversely, impact of land use changes on soil also can occur so unnoticed that land managers hardly contemplate initiating ameliorative measures. For example, forest conversion to cropland and reduction of tillage intensity can prevail as main changes of land use in some regions, whereas abandon of agricultural fields can be a major concern in other regions. In non-agricultural context, changes of land use of major interest are driven by urbanization, landscaping, engineering, mining, contamination, etc. Knowledge and understanding of soil properties and processes ensures remediation or reclamation of disturbed or damaged soils.
This session addresses contributions dealing with effect of changes in soil use on biological, chemical and physical soil properties. Particularly welcome are studies about the interaction between land use and soil heterogeneity at various scales, which apply advanced statistical and mathematical methods.

Another aspect that will be addressed in one subsession are temporal dynamics of soil hydraulic properties that occur due to soil management and natural processes over different temporal scales. Quantification of soil structural and hydrologic property dynamics require testable physically‐based models and definitive field-based experimental data. Advances in this field require integrative models that consider complex interactions between hydrologic, mechanical, and biological processes. In this subsession, research focusing on new measurement and modeling approaches will be presented.

Selected abstracts of this session will be proposed for Special Issues in international journals, such as the Journal of Plant Nutrition and Soil Science.
