Space-time variation in soil propertiesSoil properties depends on environmental, climatic, and human-induced factors, as well as on intrinsic factors/pedogenic processes that occur at the local scale and past events that are “etched” in the soil’s memory. Water erosion processesErosion processes can degrade soil healthSoil health to the point of no return—which may result in reduced yields and threaten food supply. The monetary cost of soil degradationSoil degradation globally is on a scale of tens of billions of USD per year—with some continents suffering more physical and economic consequences than others.
