Resumo: | The deposition of organic residues through mechanical harvesting of cane sugar is a growing practice in sugarcane production system. The maintenance of these residues on the soil surface depends mainly on environmental conditions. Nitrogen fertilization on dry residues tend to retard decomposition of these, providing benefits such as increased SOM. Thus, the object of this research was to evaluate the effect of different doses of nitrogen on sugar cane crop residues, as its decomposition and contribution to carbon sequestration in soil. The experiment was conducted in Dourados-MS and consisted of a randomized complete block design. Dried residues were placed in litter bags and the treatments were arranged in a split plot, being the four nitrogen rates (0, 50, 100 and 150 kg ha-1 N) the plots, and the seven sampling times (0, 30, 60, 90, 120, 150 and 180) the spit plots. Decomposition rates of residues, total organic carbon and labile carbon on soil were analysed. The application of increasing N doses resulted in an increase in their decomposition rates. Despite this, note also the mineral N application as a strategy to get higher levels of labile carbon in soil. |

A manutenção desses resíduos na superfície do solo depende principalmente das condições ambientais. A adubação nitrogenada sobre os resíduos secos tendem a retardar a decomposição desses, proporcionando benefícios como o aumento da MOS. Diante disto, o objetivo da pesquisa foi avaliar o efeito da aplicação de diferentes doses de nitrogênio sobre os resíduos culturais de cana-de-açúcar, quanto a sua decomposição e contribuição para o sequestro de carbono no solo. O experimento foi realizado em Dourados-MS e consistiu de um delineamento experimental em blocos casualizados. Os resíduos secos foram colocados em litter bags e os tratamentos foram arranjados em parcelas subdivididas, sendo as quatro doses de nitrogênio (0,50, 100 e 150 kg ha-1 N) as parcelas, e as sete épocas de coleta (0, 30, 60, 90, 120, 150 e 180 dias) as subparcelas. Foram analisados a taxa de decomposição dos resíduos, carbono orgânico total e carbono lábil no solo. A aplicação de doses crescente de N proporcionou aumento nas suas taxas de decomposição. Apesar disso, destaca-se a aplicação de N-mineral como uma estratégia de manejo para obter maiores teores de carbono lábil no solo.UEL2014-08-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa regionalapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/1385610.5433/1679-0359.2014v35n4p1751Semina: Ciências Agrárias; Vol. 35 No. 4 (2014); 1751-1760Semina: Ciências Agrárias; v. 35 n. 4 (2014); 1751-17601679-03591676-546Xreponame:Semina.
