Relações entre produtividade de Brachiaria Brizantha e atributos físicos de um latossolo do cerrado

Abstract: RESUMOEm sistema de integração lavoura-pecuária, os diversos cultivos em sistema plantio direto alteram os atributos físicos do solo, refletindo sobre a produtividade e a composição vegetal. O objetivo deste trabalho foi indicar atributos do solo com melhor correlação com a produtividade e teor de proteína da Brachiaria brizantha.

“…Therefore, both attributes (#POP and #OM), as they showed appreciable direct spatial relationship with PRO, can be used as PRO indicators, when the goal is to increase the productivity of sugarcane stalks. These results are similar to those observed by Lima et al (2007), which related direct spatial correlation in the productivity of corn forage as a function of soil density, by Cavallini et al (2010), which reported an inverse spatial correlation of dry matter of Brachiaria brizantha according to soil porosity, and by Montanari et al (2010), which described the direct spatial correlation of bean productivity with gravimetric soil moisture.…”

“…En la sabana, pastos con manejo inadecuado conducen a la degradación del suelo, llevando a limitaciones tanto por la compactación como por la pérdida de la fertilidad (Cavallini et al, 2010). La importancia de los pastos para la producción de bovinos en Brasil se debe, entre otros factores, a su bajo costo de producción (Santos et al 2009).…”

“…En el sector pecuario, el ganado de corte brasileño es caracterizado por la explotación extensiva de los forrajes con baja productividad e índices zootécnicos insatisfactorios, comparándose a otros países que exportan carne (Cavallini et al, 2010;Pariz et al, 2011).…”

“…Researches on compaction interference in agricultural productivity are numerous, regarding soil physical properties and root distribution and growth (CAVALLINI et al, 2010;SECCO et al, 2009;Silva et al, 2009;GUBIANI et al, 2013). Soil compaction can also influence agricultural machinery and implement performances, promoting an expansion in potency demand for traction (DRESCHER et al, 2011;MENTGES et al, 2010).…”
