Abstract Quantifying nitrous oxide (N 2 O) fluxes, a potent greenhouse gas, from soils is necessary to improve our knowledge of terrestrial N O losses. Developing universal sampling frequencies for calculating annual fluxes difficult, as are renowned their high temporal variability. We demonstrate daily was largely required achieve within 10% the ‘best’ estimate 28 datasets collected three continents—Australia, Europe and Asia. Decreasing regularity measurements either under- or overestimated with maximum overestimation 935%. Measurement frequency lowered using strategy based on environmental factors known affect variability, but still more than once week. Consequently, uncertainty in current global budgets associated upscaling field-based can be decreased significantly adequate frequencies.

Abstract. Agronomical and environmental benefits are associated with replacing winter fallow by cover crops (CCs). Yet, the effect of this practice on nitrous oxide (N2O) emissions remains poorly understood. In context, a field experiment was carried out under Mediterranean conditions to evaluate traditional (F) vetch (Vicia sativa L.; V) or barley (Hordeum vulgare B) greenhouse gas (GHG) during intercrop maize (Zea mays L.) cropping period. The fertilized following integrated soil fertility management (ISFM) criteria. Maize nitrogen (N) uptake, mineral N concentrations, temperature moisture, dissolved organic carbon (DOC) GHG fluxes were measured experiment. Our (adjusted synthetic rates due ISFM) pedo-climatic resulted in low cumulative N2O (0.57 0.75 kg N2O-N ha−1 yr−1), yield-scaled (3–6 g aboveground uptake−1) surplus (31 56 ha−1) for all treatments. Although CCs increased period compared F (1.6 2.6 times B V, respectively), ISFM similar at end higher C : ratio residue led greater proportion losses from fertilizer these plots when V.

Abstract Manual measurements of nitrous oxide (N 2 O) emissions with static chambers are commonly practised. However, they generally do not consider the diurnal variability N O flux, and little is known about patterns drivers such variability. We systematically reviewed analysed 286 data sets fluxes from published literature to (i) assess prevalence timing (day or night peaking) flux in agricultural forest soils, (ii) examine relationship between soil temperature different patterns, (iii) identify whether non‐diurnal factors (i.e. land management properties) influence occurrence (iv) evaluate accuracy estimating cumulative single‐daily measurements. Our synthesis demonstrates that a widespread phenomenon soils. Of analysed, ~80% exhibited ~60% peaking during day ~20% at night. Contrary many observations, our analysis only found strong positive correlations ( R > 0.7) one‐third sets. Soil drainage property, water‐filled pore space (WFPS) level use were also potentially certain patterns. work demonstrated mid‐morning yielded daily emission estimates smallest average bias compared made other times day, however, it could still lead significant over‐ underestimation due inconsistent This inconsistency reflects inaccuracy using predict time flux.
