A fraction of the added Cu ions forms very stable complexes or chelates, and the recovery of the Cu adsorbed with 0,05 N HCL solutions was not quantitative in most cases. Therefore a high Cu concentration was observed in the soil equilibrium solution, wich being mobile can contribute, effectively to the nutrition of the plant.6 páginasapplication/pdfCobre||copper||Cobre||cuivreCaña de azúcar||sugar cane||cana de açúcar||canne à sucreSuelo||soil||solo||solBrasil||Brazil||Brasil||BrésilSede CentralArtículo
