Efeito da adição de doses de biocarvão no movimento de íons em colunas de solo

Abstract

The use of pyrolyzed residues, known as biochar, is a viable option for improving the chemical characteristics of the soil, as well as being able to reduce the emissions of gases from the effect of agricultural soils. Biochar can be produced through the most varied sources of biomass, however, its quality changes according to the nature of the biomass. The production of urban and industrial waste in large urban centers causes several pollution problems and are considered environmental liabilities with potential for contamination of soil and water. The final destination of Coconut Fiber and the Sewage Side has been causing these problems in metropolitan areas such as Fortaleza, in order to evaluate the movement of ions along soil columns, after the application of Doses of biochar, submitted to percolation with water, besides verifying the effect on the values of pH and electrical conductivity. The experiment was conducted in a greenhouse at EMBRAPA - Tropical Agroindustry, in Fortaleza / CE. The experimental design was the completely randomized, in a 5 x 2 factorial scheme, with four replications. The treatments consisted of five doses of biochar (0, 5, 10, 20 and 40 Mg ha-1) and two percolation cycles (30 and 60 days), totaling 40 experimental plots.
