Estoques de carbono e nitrogênio em frações da matéria orgânica de solos cultivados com eucalipto nos sistemas convencional e fertirrigado

Abstract: O presente estudo teve o objetivo de avaliar os estoques de C e N nas frações lábeis e estáveis da MOS e da biomassa microbiana em resposta ao cultivo florestal com o uso de fertirrigação quando comparado ao cultivo convencional. Para tanto, duas áreas cultivadas com eucalipto num mesmo solo (Argissolo Amarelo), mas com manejos fertirrigado e convencional foram amostradas nas camadas de 0-10, 10-20, 20-40, 40-60 e 60-100cm de profundidade na linha e entrelinha de cultivo. A amostragem da entrelinha foi justifi… Show more

“…Thus, good practices and management of vegetation and soil are highly recommended for the maintenance and increase of soil C in agricultural lands (Minasny et al 2017;Lal 2018;Chenu et al 2019). Some of the management techniques that affect the inputs and content of soil C are tree pruning (Oelbermann et al 2006;de Carvalho et al 2014), thinnings (Ma et al 2018), lime (Mosquera-Losada et al 2015), fertilizer application (Adams et al 2005), irrigation (Pegoraro et al 2010), and site preparation intensity (Garcia-Franco et al 2014).…”
