| ABSTRACT The objective of this study was to evaluate nitrogen losses by NH3 volatilization and quantify the upward and downward NO3- flows in Latosol cultivated with arabica coffee. An experiment was set in 2010, in Viçosa-MG, Brazil (20º 41’ S and 42º 48’ W), in a randomized block design in a (3 x 2) + 1 factorial arrangement with three nitrogen doses (200, 400 and 600 kg ha-1), two forms of urea (conventional and NBPT urease inhibitor-treated) and one additional treatment without nitrogen fertilization, with four replicates. Semi-open type chambers were installed to quantify NH3 volatilization. To determine the concentration and flow of NO3- a soil solution extractor was installed in each plot at a 1-m depth together with three tensiometers at depths of... |
