This study evaluates the chemical changes in the Zn, Cu and Mn contents in a typical red clay Ultisol in the municipality of Braço do Norte, SC, Brazil during the corn (Zea mays) and oat (Avena sativa) crop cycle of a no-tillage system. It was fertilised with pig slurry and mineral fertilizer (urea), applied by deep bedding, at two rates: the recommended dose of N and twice for the corn crop. Six measurements were made at depths of 0-15, 15-30, 30-45 and 45-60 cm, during the corn crop cycle in the 2007 / 8 harvest. In general, increases in the Zn, Cu and Mn contents occurred in soil with applications of pig manure. During the corn cycle, higher Zn, Cu and Mn concentrations were found in the surface layer (0-15 cm), and these values decreased in depth. In the treatment using fertilization with deep bedding system twice the N recommendation (BD2x) in the soil surface layer, the highest Zn, Cu and Mn concentrations were observed. Although the levels of these elements were higher in the surface layer, their levels are not considered critical for environmental toxicity risks. |
