Resumo
As pastagens constituem a base dos sistemas de produção de bovinos, o que evidencia sua importância e a necessidade de outras práticas de manejo que resultem em maior eficiência desses sistemas. Assim, este trabalho teve como objetivo avaliar os atributos químicos do solo (pH, Ca, Mg e H+Al), o potencial produtivo e a composição química do capim braquiária (Brachiaria decumbens Stapf) em solo corrigido com diferentes doses de calcário e escória silicatada. O experimento foi conduzido em ambiente protegido no período de 2006/2007, na UNESP de Ilha Solteira. Foram testadas cinco doses de calcário e escória silicatada, 0,0; 0,5; 1,0; 1,5; 2,0 vezes a dose recomendada. O delineamento experimental foi inteiramente casualizado, com quatro repetições. Avaliou-se a composição química do solo após incubação dos corretivos, o perfilhamento, a matéria seca, proteína, FDN (fibra em detergente neutro) e FDA (fibra em detergente ácido). Ambos os corretivos proporcionaram ao solo efeito positivo em relação ao pH e teores de cálcio e magnésio. As variáveis matéria seca e FDA não foram influenciadas significativamente pelos tipos e doses de corretivos.
Pastures are the basis of cattle production systems, evidencing their importance and the need for other management practices that result in higher efficiency of these systems. This study aimed to evaluate the soil chemical properties (pH, Ca, Mg and H+Al), the potential production and the chemical composition of signal grass (Brachiaria decumbens Stapf) in soil amended with different limestone doses and calcium silicate slag. The experiment was carried out in a greenhouse, in the period 2006/2007, at the Universidade Estadual Paulista, Ilha Solteira-SP. Five doses of limestone and calcium silicate slag were tested, 0.0; 0.5; 1.0; 1.5; 2.0 times the recommended dose. A complete randomized design was used with four repetitions. Soil chemical composition was evaluated after incubation with the amendment, tillering, dry matter, protein, NDF (neutral detergent fiber) and ADF (acid detergent fiber). Both amendments provided to the soil positive effect in relation to the pH and content of calcium and magnesium. The variables dry matter and ADF were not significantly influenced by the types and doses of the amendments.
