From: Impact of desertification on soil and plant nutrient stoichiometry in a desert grassland
Response of C:N:P stoichiometric ratio of plant tissue (leaf, litter and root) to desertification. Tissue nutrient ratio were measured in five different desertification stages: potential desertification stage (PD), light desertification stage (LD), moderate desertification stage (MD), severe desertification stage (SD), very severe desertification stage (VSD). Different lowercase letters indicate differences at P < 0.05. Values represent treatment means ± standard deviation, n = 3.
