IMPACTO DE áGUAS DE IRRIGA O E RESíDUOS DE DIFERENTES ORIGENS NOS TEORES DE MICRONUTRIENTES NO SOLO E NA CANA-DE A úCAR

O objetivo deste trabalho foi avaliar o uso do composto de lixo e biofertilizante como fonte de nutrientes, e oresíduo do processamento da bauxita como corretivo da acidez do solo, irrigada com água potável e servida. Para tanto foiconduzido experimento em vaso, utilizando-se solo Argissolo Vermelho Amarelo, sendo avaliadas as concentra esmacronutrientes no solo (Cu, Fe, Mn e Zn) na camada de 0-20 cm e nas folhas de cana-de-a úcar (B, Cu, Fe, Mn e Zn). Osdados obtidos evidenciaram que a aduba o com biofertilizante aumentou significativamente os teores de Cu e Zn no solo(0,56 e 0,63 mg dm-3, respectivamente), a aplica o de resíduo do processamento da bauxita elevou as concentra es demanganês, n o foram observados mudan as para Fe. Já nas folhas de cana-de-a úcar o uso de resíduo do processamento dacana-de-a úcar elevou os teores de todos os micronutrientes, a aplica o de biofertilizante e composto de lixo elevou osteores de Cu nas folhas (0,80 e 1,00 mg dm-3 respectivamente) entretanto houve uma redu o do teor de Mn (84,66 e 89,66mg dm-3 respectivamente). A qualidade da água de irriga o, potável ou servida, n o influenciou as concentra es demacronutrientes no solo, bem como os teores desses elementos na planta.The agricultural use of organic residues and industrial is an alternative of exploitation with fertilizationand source organic matter to the soil. In this direction, the objective of this research was to evaluate the use of the urbansolid waste and biofertilizer as nutrient source, and residue of the bauxite processing as agricultural liming materials of thesoil, irrigated with potable water and wastewater. For in such a way experiment in vase was lead, under soil Alfisol, beingevaluated the micronutrient concentrations in the soil (Cu, Fe, Mn and Zn) in the layer of 0-20 cm and leaves of sugar cane(Cu, Fe, Mn and Zn). The gotten data had evidenced the fertilization with biofertilizer increased texts of Cu significantlyand Zn in the soil (0.56 and 0.63 mg dm-3, respectively), the application of residue of the processing of the bauxite raisedthe manganese concentrations, had not been observed changes for Fe. Already in sugar cane leaves the use of residue of theprocessing of the sugar cane raised texts of all the micronutrients, the application of biofertilizer and made up of urbansolid waste raised texts of Cu in leaves (0.80 and 1.00 mg dm-3 respectively) however had a reduction of the text of Mn(84.66 and 89.66 mg dm-3 respectively). Ions studied in the leachate water its addition to the soil and in function of eachtreatment is proportion
