Impacts of Sewage Sludge in Tropical Soil: A Case Study in Brazil
Figure 1
Effect of sewage sludge rates (FS: Franca sludge; BS: Barueri Sludge; NPK-F: recommended mineral fertilization compared to Franca sludge; NPK-B: recommended mineral fertilization compared to Barueri sludge) over the percentage of diseased plants, pH and electric conductivity of the soil, and Fusarium population in the soil. Left column contains data referring to second planting; right column refers to third planting. Bettiol [15].
