Resumo: The objective of this work was to investigate the impact of the application of wood biochar, combined with N fertilizations, on N2O-N fluxes, nitrogen availability, and water-filled pore space (WFPS) of a clayey Oxisol under rice (wet season) and common bean (dry season) succession. Manual static chambers were usedto quantify N2O-N fluxes from soil immediately after a single application of wood biochar (32 Mg ha-1) andafter four crop seasons with N applications (90 kg ha-1 N). Soil ammonium (N-NH4 +) and nitrate (N-NO3-) availability, as well as WFPS, was measured together with N2O-N fluxes. There was no interaction between biochar and N fertilization regarding N2O-N fluxes in any of the four seasons monitored, although these fluxes were clearly enhanced by N applications. At 1.5 and 2.5 years after biochar application, the WFPS decreased. In addition, in the seasons characterized by low WFPS, N2O-N fluxes and soil N-NO3- and N-NH4+ availability were enhanced after N applications. Long-term experiments in the field are important to quantify the impacts of biochar on N2O-N fluxes and to determine the dynamics of these fluxes on soil-related variables.

Câmaras estáticas manuais foram utilizadas para quantificar os fluxos de N2O-N no solo logo após uma única aplicação de biochar (32 Mg ha-1) e após quatro épocas de cultivo com aplicações de N (90 kg ha-1 de N). A disponibilidade de amônio (N-NH4+) e de nitrato (N-NO3-) no solo, bem como o EPPA, foi medida juntamente com os fluxos de N2O-N. Não houve interação entre biochar e fertilização nitrogenada quanto aos fluxos de N2O-N, em nenhuma das quatro épocas monitoradas, apesar de esses fluxos terem aumentado com as aplicações de N. Aos 1,5 e 2,5 anos após a aplicação do biochar, o EPPA diminuiu. Além disso, nas épocas caracterizadas por reduzido EPPA, os fluxos de N2O-N e a disponibilidade de N-NO3- e N-NH4 + no solo aumentaram após as aplicações de N.Experimentos em campo de longa duração são importantes para quantificar o impacto do uso de biochar sobre os fluxos de N2O-N e para determinar a dinâmica desses fluxos sobre as variáveis relacionadas ao solo.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraEmpresa Brasileira de Pesquisa Agropecuária (Embrapa)Conselho Nacional de Pesquisa e Desenvolvimento (CNPq)Climate Food and Farming Research Network (CLIFF)Climate Change Agriculture and Food Security (CCAFS).Carvalho, Marcia Thais De MeloMadari, Beata EmokeBastiaans, Lammertvan Oort, Pepijn Adrianus JohannesLeal, Wesley Gabriel de OliveiraSouza, Diego Mendes deSantos, Roberto Carlos Gomes dosMatsushigue, IvaMaia, Aline de Holanda NunesHeinemann, Alexandre BryanMeinke, Holger2016-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/22508Pesquisa Agropecuaria Brasileira; v.51, n.9, set. 2016: Número Temático O solo como fator de integração entre os componentes ambientais e a produção agropecuária; 1203-1212Pesquisa Agropecuária Brasileira; v.51, n.9, set. 2016: Número Temático O solo como fator de integração entre os componentes ambientais e a produção agropecuária; 1203-12121678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/22508/13467https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/22508/14544https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/22508/14545https://seer.sct.embrapa.br/index.php/pab/article/downloadSuppFile/22508/14563Direitos autorais 2016 Pesquisa Agropecuária Brasileirainfo:eu-repo/semantics/openAccess2016-10-31T17:52:12Zoai:ojs.seer.sct.embrapa.br:article/22508Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2016-10-31T17:52:12Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
