Abstract Isotopic tracer methods using 15 N or other isotopes provide insights into the sources and underlying transformations leading to 2 O emissions from agricultural soils. However, homogeneous labelling of naturally structured soil in field is challenging since macropore flow must be avoided while application performed a limited timeframe. Therefore, we tested infiltration pattern several consequently developed drip (DA) for larger scales individual dropper bottles. We proof concept...
Abstract Source determination of N 2 O has often been performed using stable isotope incubation experiments. In situ experiments with isotopic tracers are an important next step. However, the challenge is to distribute in field as homogeneously possible. To examine this, a bromide solution was applied stand‐in tracer either watering can, sprayer, or syringes relatively dry (25% gravimetric moisture content) wet (30%) silt loam. After 1 h, samples were taken from three soil depths (0‐10 cm),...
