Leaf and stem concentrations of total N (%), P (g kg⁻¹ d.m.) and K (g kg⁻¹d.m.) in Rosmarinus officinalis plants for the fertilization treatments: Control, InOrg, CS_Low, CS_High, PS_Low and PS_High. Mean values ± standard errors (n = 3) are shown. Different letters indicate significant differences among fertilization treatments (p < 0.05). Asterisks indicate significant differences between leaf and stem values (p < 0.05).
