The seasonality of leaf nutrient concentration in Chinese woody plants

We compiled a database of seasonally varying concentrations of nine foliar nutrients (N, P, K, Ca, Mg, Fe, Mn, Zn, and Cu) for woody plants in China based on a survey using the Web of Science (http://isiknowledge.com), Google Scholar (https://scholar.google.com), and China National Knowledge Infrastructure (http://www.cnki.net/). This database supports the analysis of seasonal variation in leaf nutrient concentration of Chinese woody plants.
