Lucratividade e risco de sistemas de produção de grãos com pastagens, sob sistema plantio direto

Abstract: O objetivo deste estudo de cinco anos foi avaliar o desempenho de cinco sistemas de produção: sistema I (trigo/soja, ervilhaca/milho e aveia branca/soja); sistema II (trigo/soja, pastagem de aveia preta + ervilhaca/milho e aveia branca/soja); sistema III [pastagem perene de estação fria (festuca + trevo branco + trevo vermelho + cornichão)]; sistema IV [pastagem perene de estação quente (pensacola + aveia preta + azevém + trevo branco + trevo vermelho + cornichão)]; e sistema V (alfafa para feno). As parcelas … Show more

“…Hence the importance of crop-livestock integration (CLI) in no-tillage system (NTS), which makes it an important alternative to occupy these areas and increase the sustainability of rural productions, providing: (i) biological and economic advantages (BALBINOT JUNIOR et al, 2009); (ii) enhancing and maximizing the exploitation land use (LANDERS, 2007); (iii) increasing yield and risks reduction (FONTANELI et al, 2006); (iv) carbon sequestration and reducing the emission of greenhouse gases -global warming effect - (CERRI et al, 2010). In Brazil southern, there is great potential for beef production in pure or mixed winter pastures (ASSMANN et al, 2004;NICOLOSO;LANZANOVA;LOVAZO, 2006).…”

“…Outras formas de ILP com pastagens anuais de inverno, em cultivo exclusivo ou em consórcio de gramíneas e leguminosas, têm sido estudadas na região Sul do Brasil (FONTANELI et al, 2006;SILVA et al, 2007;LUNARDI et al, 2008;CARVALHO et al, 2010), com resultados favoráveis principalmente em relação ao aumento da produtividade de grãos de milho e soja sobre os resíduos das pastagens após a dessecação, conforme revisão de BALBINOT JÚNIOR et al (2009).…”

“…In Southern Brazil, both research and commercial farms have demonstrated that crop-livestock systems can improve net returns in comparison to grain crops alone (Fontaneli et al, 2006). However, soil compaction due to animal trampling decreases the soil physical quality needed for growing plants (Imhoff et al, 2000).…”

“…Organic matter can be incorporated into small pores, creating bonds between particles and increasing soil strength in larger aggregate sizes (Guérif, 1994). On the other hand, the specific adsorption of organic compounds onto clays can modify the balance of electrical charges and decrease aggregate tensile strength (Goldberg et al, 1990).…”
