LILAS4SOILS Protocol for sampling and data collection (Deliverable D4.1) provides guidelines for selecting the soil sampling design more adequate to the characteristics of the project area (i.e., demo-sites at each Living Lab) and that is mindful of the accuracy-costs trade-offs of MRV. The deliverable includes field and laboratory protocols to measure several soil properties during the project, to assess the effects of CFPs on SOC stocks and other indicators of soil health, soil functions or threats to soil.
