Abstract:
The aim of the survey 200 soil is to quantify soil physical and chemical properties (soil bulk density, ph, conductivity, and nutrient content) across the CAP LTER study area to form a key component of the long-term monitoring activities at the CAP site, with repetition of the survey every 5 years. It provides a basis for scaling up and extrapolating data from more site-specific studies to the entire study area.
