This study aimed at evaluating soil nitrous oxide (N2O) and methane (CH4) emissions from integrated farming systems. Soil N2O and CH4 fluxes were assessed in a subtropical Cambisol in southern Brazil, using manual static chambers, over two years, in five farming systems (cropland, livestock, integrated crop-livestock, integrated livestock-forestry, and integrated crop-livestock-forestry). The study was conducted in four growing seasons: summer-1, winter-1, summer-2, winter-2. Integrated farming systems had lower soil N2O emissions than livestock. The observed reduction was possibly due to lower water-filled pore space (WFPS) in soils under integrated systems (average 59.5?64.7%, vs 70.4% in livestock) as indicated by correlation (r = 0.74). Cropland, including cover-crops and maize, also had lower N2O emission (by 40%) relative to livestock, of levels similar to those observed in integrated systems. Methane was consumed in soil, but it was not affected by farming systems, and offset only ~1.4% of the N2O emissions. In the rainiest season of summer-2, the soil had the highest WFPS (on average 71.4%) and thus the highest N2O emission (on average 9.79 kg N2O-N ha−1 season−1) and the lowest CH4 consumption (on average − 0.40 kg CH4-C ha−1 season−1); while the opposite trend occurred in the driest season of winter-2 (on average 57.3% WFPS; 0.64 kg N2O-N ha−1 season−1 and -0.90 kg CH4-C ha−1 season−1). Integrated farming systems including crop-livestock, livestock-forestry and crop-livestock-forestry reduced soil N2O emissions relative to sole livestock by 27?40%, but did not affect CH4 emissions. Seasonal variations of precipitation, and therefore WFPS were driving factors of the N2O and CH4 emissions. Overall, integrated farming systems show the potential to mitigate soil N2O emission compared to livestock system.

Resumo: Este trabalho disponibiliza informações em base territorial para auxiliar as atividades de monitoramento e controle de Helicoverpa armigera (Lepidoptera: Noctuidae). Diante do pouco tempo de ingresso e face às peculiaridades biológicas e comportamentais do inseto e da extensão territorial brasileira, H. armigera demanda monitoramento e conhecimento de avanço de fronteiras de seus hospedeiros para readequar ações estratégicas de controle. Este trabalho, a partir de técnicas de geoprocessamento em ambiente de Sistema de Informação Geográfica (SIG), disponibiliza informações sobre localizações prioritárias para monitoramento de H. armigera no Cerrado brasileiro, considerando áreas plantadas com cultivos hospedeiros, preferenciais (algodão, soja, milho, feijão e tomate), perenes (laranja e café) e florestais (eucalipto/pinus) no ano de 2014. O resultado da priorização indica a necessidade de ações de vigilância em 213 municípios, localizados em 90 microrregiões de 11 estados brasileiros, a saber, Minas Gerais, São Paulo, Paraná, Rondônia, Tocantins, Goiás, Mato Grosso do Sul, Mato Grosso, Bahia, Maranhão e Piauí, além do Distrito Federal. Desse modo, o método proposto orienta locais mais propícios à intensificação de controle. -- Abstract:The present work makes territorial-base information available to collaboratewith Brazilian crop protection activities toward the monitoring and controlling of Helicoverpa armigera(Lepidoptera: Noctuidae). Taking into account its recent time of ingression in Brazil, its biological and behavioral peculiarities, and also the Brazilian territorial extension, the insect demands monitoring and knowledge of its crop-host frontier advancementto subside strategical controlactions. This work, based ongeoprocessing techniques made on Geographic Information System (GIS), providesinformation on priority areas for the monitoring of H. armigerain Brazilian Cerrado Biome (similar to Savanna) planted with host-crops (cotton, soybean, corn, bean andtomato), perennial (orangeand coffee), and forest plantations (eucalyptus and pines), considering data available for 2014.
