Much attention has been paid to the stoichiometry of carbon (C), nitrogen (N), and phosphorus (P) because of their significance for plant growth and climate change. However, other nutrients, such as sulfur (S), are often ignored. In this study, we analyzed the stoichiometry of N, P, and S in leaves of 348 plant species in China’s forests. The results show higher N content and higher molar ratios of...
Covering extensive parts of China, Karst landscapes are exceptional because rapid and intensive land use change has caused severe ecosystem degradation within only the last 50 years. The twentieth century intensification in food production through agriculture has led to a rapid deterioration of soil quality, evidenced in reduced crop production and rapid loss of soil. In many areas, a tipping point...
