Fig 4. PCA loading plot of the first two principal components for a) grasses in monoculture and b) grasses in mixture.

Fig 4

Gradient colour scales and arrow length represent the percentage of variation explained by each variable along the principal component. RGR 35–70 = Relative growth rate (kpixels day-1), Ex P = Extractable P (mg g-1), Ex N = Extractable N (mg g-1), Shoot P = Shoot P (mg g-1), Shoot N = Shoot N (mg g-1).
