From: Impact of desertification on soil and plant nutrient stoichiometry in a desert grassland
Correlation matrix among nutrient and stoichiometry of plant leaf, root, litter and soil. N = 10. Note: ‘×’ indicates correlation is non-significant (P > 0.05); blue indicates positive correlations and red indicates negative. C, carbon (%); N, nitrogen (%); P, phosphorus (%); C:N, the ratio of carbon to nitrogen; N:P, the ratio of nitrogen to phosphorus; C:P, the ratio of carbon to phosphorus.
