| During a summer crop in Mediterranean climate, irrigation management and type of fertilizer are two of the most important factors influencing emissions of greenhouse gases (GHGs) from irrigated agricultural soils. Localized irrigation techniques such us drip irrigation (DI) influences soil moisture producing wet and dry areas due to water distribution pattern, and therefore influences the processes responsible of the production and consumption of GHGs (Sanchez-Martin et al., 2008). The irrigation frequency together with the high evapotranspiration during summer season, play an important role in soil microbial activity and therefore in the emissions of GHGs. A targeted combination between N fertilizer and irrigation frequency could be a key factor for a more sustainable cropping system. A field experiment was carried out in summer 2011 under melon crop in order to evaluate the emissions of two of the most important GHGs, nitrous oxide (N2O) and carbon dioxide (CO2) in relation to irrigation frequency and type of fertilizer. | |
