Mineralização do nitrogênio da palhada de milheto dessecado com herbicidas

Abstract: RESUMOPesquisas recentes verificaram que a utilização de glyphosate ou amônio glufosinate para dessecação de culturas de cobertura em sistemas conservacionistas podem reduzir o conteúdo de nitrogênio na palha formada. Neste contexto. O objetivo deste trabalho foi avaliar a mineralização do N da palhada de milheto em função da utilização dos herbicidas glyphosate e glufosinato de amônio e o aproveitamento do N pela cultura do milho. Utilizou-se o delineamento inteiramente casualizado, com seis tratamentos e cin… Show more

“…With the increase in the C/N ratio, the stubble mineralization rate can decrease. In fact, Damin et al (2009;2010c) assessed the N decomposition rate present in pearl millet and black oat stubble after the application of glyphosate and glufosinate ammonium. They observed an increase in the stubble dry matter remaining on the soil surface and a decrease in N liquid mineralization (Tables 2 and 3).…”
