Global Soil Carbon and Nitrogen Profiles from Zinke Database
Soil carbon and nitrogen measurements for over 3,500 soil profiles collected worldwide. The database originated from analyses by Zinke about 40 years ago, incorporating samples from California, Italy, Greece, Iran, Thailand, Vietnam, Amazonian areas, U.S. forests, and the literature. It provides a baseline for natural vegetation soil pools, with data collection methods including dry combustion, wet combustion, and Kjeldahl nitrogen analysis.
