Descripción
To assess metal mobility in pruning waste and biosolids compost (pH6.9 and total concentration of metals in milligram per kilogram of Cd 1.9, Cu 132, Fe 8,513, Mn 192, Pb 81, and Zn 313), shrubs species Atriplex halimus and Rosmarinus officinalis were transplanted in this substrate and irrigated with citric acid (4 gL?1, pH2.9) and nutrient solution daily for 60 days. Citric acid significantly increased the con-centrations of soluble Mn and Fe in the nutrient sub-strate solution measured by suction probes, while other metals did not vary in concentration (Cu and Zn) or were not observed at detectable levels (Cd and Pb). In plants, citric acid significantly increased the concentrations of Cu (2.7±0.1?3.3±0.1 mgkg?1), Fe (49.2±5.2?76.8±6.8 mgkg?1), and Mn (7.2±1.1?11.4± 0.7 mgkg?1) in leaves of R. officinalis, whereas the concentration of only Mn (25.4±0.3?42.2 ±2.9 mg kg?1) was increased in A. halimus. Increasing Feand Mn solubility by citric acid addition indicates the possi-bility of using it to improve plant nutrition. The mobility of metals in this substrate was influenced for the concentration of the metal, the degree of humification of organic matter and its high Fe content.
