Abstract:
... The soil organic carbon (SOC) content of many Mediterranean soils is low (∼1%) and this hinders both economic and ecologic progress. The climate in much of the Mediterranean region (low annual precipitation, cool wet winters, hot dry summers), combined with traditional agricultural practices has a major impact on the carbon (C) cycle. To increase our knowledge of C fluxes in Mediterranean agro-eco ...

Abstract:
... Mediterranean agricultural areas are characterised by low soil organic C (SOC) contents and as a consequence they are often degraded and highly vulnerable to environmental changes. Climate change is expected to have a large impact upon these areas but they may be key for mitigation of its effects given their potential for soil C sequestration. Several approaches have been proposed to evaluate clim ...

Abstract:
... Many recent reviews and meta-analyses of N2O emissions do not include data from Mediterranean studies. In this paper we present a meta-analysis of the N2O emissions from Mediterranean cropping systems, and propose a more robust and reliable regional emission factor (EF) for N2O, distinguishing the effects of water management, crop type, and fertilizer management. The average overall EF for Mediter ...

Abstract:
... Nitrous oxide (N2O) emissions from the Chilean agricultural sector are primarily associated with the use of nitrogen (N) fertilizers, so that the use of nitrification and urease inhibitors may represent a potential mitigation option. However, their effectiveness in volcanic ash soils with high organic matter is still uncertain. In this study, the effect of Dicyandiamide (DCD) and N-(n-butyl) thiop ...

Abstract:
... Little work has been done on nitrous oxide (N2O) emissions from nitrogen-fertigation systems, despite the greater degrees of control allowed over fertilizer N fate. More fertigation users are adopting high-frequency (HF) N application schedules to improve nitrogen use efficiency and reduce nitrate (NO3−) leaching. The possibility is raised that this practice may also lower N2O emissions, through e ...

Abstract:
... Substitution of conventional mineral fertilizers with organic sources can avoid the environmental problems associated with high concentrations of intensive livestock production in some Mediterranean areas. Some management practices, such as the use of nitrification inhibitors or more efficient irrigation techniques (e.g., drip irrigation), have been suggested as effective alternatives to mitigate ...

Abstract:
... To assess the spatial and temporal dynamics of carbon (C) at regional scale induced by land use and soil type, we performed a simulation study, based on a bio-physical model (RothC10N) combined with a spatially explicit database including soil, land use and climate. RothC10N was linked to GIS and outputs were interpolated using Empirical Bayesian Kriging (EBK) to estimate the C stocks and CO2 emis ...

Abstract:
... Agriculture in the Mediterranean basin is currently contributing to greenhouse gas emissions (GHG) and in the future is expected to be strongly affected by climate change. Increasing soil organic carbon (SOC) via soil organic matter (SOM) improvement is widely regarded as a way to both mitigate and adapt to climate change. Using as a case study the Mediterranean coastal area in Spain, which is reg ...

In Mediterranean areas high precipitation variability and crop dependence on soil water availability make the interaction between climate and agricultural management a key issue for mitigating N2O emissions. In this study we used the STICS model to capture the effect of a water deficit gradient and precipitation variability on N2O emissions and mitigation strategies (i.e. N fertilizer type, grain ...

Abstract:
... Nitrogen fertilizer application timing and the use of nitrification inhibitors are currently promoted as agronomic practices with potential to reduce nitrous oxide (N2O) emissions. However, the efficacy of these practices is to a large extent regulated by weather variability, particularly rainfall and temperature. This is primarily the case for rainfed crops under semiarid Mediterranean climate, w ...

Abstract:
... Mediterranean soils, which are carbonate-rich and organic matter-poor, are prone to erosion and important carbon losses due to seasonal changes associated with dry summers and wet winters. The use of thermophilic digested sewage sludge (TSS) in these agricultural systems, as a soil amendment, has been acknowledged as an interesting way to supply organic matter and nutrients. Data on the long-term ...

Abstract:
... Rice paddy fields are one of the largest anthropogenic sources of methane (CH4), the second most important anthropogenic greenhouse gas (GHG) after carbon dioxide (CO2). For this reason most studies on the GHG budget in these agricultural systems focus on the evaluation of CH4 production. However, these systems also exchange other GHGs with the atmosphere, such as CO2 and nitrous oxide (N2O). To e ...
