Broad-scale soil monitoring schemes

Soil resources provide many important ecosystem goods and services. However, they are at risk from a variety of threats operating over a broad range of scales.

Therefore, monitoring soil quality and condition is essential in order to detect adverse changes in their status at an early stage
