Fertilização com N e S na recuperação de pastagem de Brachiaria brizantha cv. Marandu em neossolo quartzarênico

Abstract: RESUMO -Com o objetivo de avaliar a resposta de pastagens degradadas de Brachiaria brizantha cv. Marandu ao uso de diferentes doses de fertilização com N e S, foi desenvolvido um experimento em campo durante dois anos, em área de cerrado em blocos ao acaso. Foram avaliados sete tratamentos, seis com diferentes combinações de doses de N e S e uma testemunha (pastagem degradada). As combinações foram: 70 kg ha -1 N sem enxofre, 140 kg ha -1 N sem enxofre, 210 kg ha -1 N sem enxofre, 70 kg ha -1 N e 77 kg ha -1 S… Show more

“…As the mineral elements were promptly available in this treatment, microbial activity was probably more intense, increasing OM mineralization. The OM content was similar to that observed by Oliveira et al (2005), who reported a decrease of OM content over time.…”

“…These differences may be related to the management systems adopted in the different areas. The greater availability of Ca and Mg, as reported in the plots of Tapes, may be related to the application of lime in the soil, a technique widely used for improving pasture conditions in native pastures (OLIVEIRA et al, 2005). The proper use of lime in the soil may promote plant growth by neutralizing elements, such as iron and exchangeable aluminum; thus, optimizing the effective cation exchange capacity and availability of micronutrients, in addition to serving as a source of Ca and Mg (RAIJ, 2011).…”

“…Em trabalhos de adubação para recuperar pastagens degradadas tem-se observado maiores produções de forragem no segundo ano, em relação ao primeiro (CUNHA et al, 2001;OLIVEIRA et al, 2003OLIVEIRA et al, , 2005 e este fato pode estar relacionado à necessidade de recuperação das estruturas da planta forrageira, como a coroa e o sistema radicular para que a mesma possa expressar seu potencial de resposta em produtividade (OLIVEIRA et al, 2003).…”
