Atributos químicos de Latossolo sob plantio direto adubado com esterco de bovinos e fertilizantes minerais/Chemical attributes of Oxisol in no-tillage system fertilized with manure from cattle and mineral fertilizers

Organic fertilization in no-tillage system (NTS) has been used in regions milk production, in an order to provide nutrients for crops and provide a destination for high production of animal waste. The aim of this study was to evaluate the chemical attributes of an Oxisol, a function of organic fertilization with liquid manure from dairy cattle (LMDC) and mineral fertilizers. The experiment was conducted under NTS with crop rotation including legumes and grasses. After six years of fertilizer management of crops, soil was collected from five depths (0-0.05, 0.05-0.10, 0.10-0.30, 0.30-0.50 e 0.50-0.80 m). The samples were determined the chemical pH, H^sup +^+Al^sup 3^+, Al^sup 3+^, Ca^sup 2+^, Mg^sup 2+^, K^sup +^,electrical conductivity (EC), bases saturation (V), Ca^sup 2+^/Mg^sup 2+^ ratio, total organic C (TOC), B, Cl, Fe, Cu, Zn and Mn. The mineral fertilizers acidify the soil, raised the K^sup +^, P and EC and, changed the Zn and Cu contents.
