Root Morphology and Chemistry Data Collection in Plant Study

This dataset includes detailed metadata on root characteristics, such as diameter, branching intensity, mycorrhizae type, along with root chemistry data like nutrient concentrations and stable isotopic values. Soil dynamics, including temperature and texture, and climate information are also documented. A comprehensive resource for studying plant-root interactions and ecosystem dynamics.
