Abstract
The aim of this study was to evaluate the transport of metals in three different depths of a vegetated soil with cane sugar, organic compost as fertilizer using and bagasse ash. The experiment was conducted in areas of a sugarcane mill in the central state of Goiás, Brazil. Six areas were sampled at five points each and at different depths (0-60 cm). Were evaluated the concentrations of metals in the soil, such as P, K, Ca, Mg, Cu, Mn and Cr, beyond the parameters of soil fertility, P, organic matter, pH, H + Al, K, Ca, Mg, CEC, sum of bases (SB), base saturation (V) and aluminum saturation (m Al). At the end of these analyzes, the data were subjected to analysis of variance and regression. The results for the fertility of the soils indicated that in general nutrient levels were higher for the topsoil. The application of gray promoted significant (Pr < 0,05) in total concentrations of Cu, Mn and Cr in soil at three depths studied and Mg at intermediate depth (20-40cm). Different years of application of organic compost influenced only the total concentrations of P and Cu in the topsoil. While in subsequent layers, there are significant differences only for K and Ca in layers 20-40cm and 40-60cm, respectively.
