Animal manures are suspected to be a major source of nitrate leaching due their low nitrogen use efficiency (NUE) by crops. However, actual measurements from animal manure under field conditions scarce. In an on-farm trial in Switzerland over 2.5 years, we used 15N labelling trace the fate N cattle slurry soil-plant system and test whether more was leached than mineral fertiliser. The experiment conducted on two neighbouring fields with loamy soil agricultural area Swiss midlands, where...
Pollution of ground-and surface waters with nitrates from agricultural sources poses a risk to drinking water quality and has negative impacts on the environment. At national scale, gross nitrogen budget (GNB) is accepted as an indicator pollution caused by nitrates. There is, however, little common EU-wide knowledge application its comparability at farm level for detection monitoring mitigation measures. Therefore, survey was carried out among experts various European countries in order...
Abstract While floating near the sea surface plastic debris interacts with a number of external factors, including many different organisms. Seabirds have most extensive documented history interactions plastics, through ingestion, entanglement, and nest construction. In present study, eight seabird species from South Pacific Ocean were used as proxy to determine potential patterns removal marine debris, three hypotheses tested in relation their feeding habits nesting areas. Plastics abiotic...
Abstract Targeted use of animal manures as a nitrogen (N) fertilizer is challenging because their poorly predictable N value. An enhanced understanding transformation processes in soil under field conditions necessary to better synchronize availability and crop demand. 15 labeled cattle slurry, produced by feeding heifer with ryegrass hay, was used an on-farm trial on two neighboring fields, cropped maize or grass-clover, order assess uptake dynamics the topsoil. Recovery applied total plant...
Fertilisation with animal manure has a long-standing tradition as way to close nutrient cycles on farms. However, the fate of nitrogen (N) from in soil beyond year application remains poorly understood. The aim this research was understand residual N fertiliser value mineral (Min) and cattle slurry (Slu) relation partitioning fertilisers different physical fractions. To end, we characterised 15N-labelled Min Slu organic matter (SOM) fractions two years after field related it plant uptake N....
Abstract Animal manures are valuable multi‐nutrient fertilizers, but their short‐term nitrogen (N) use efficiency (NUE) by plants is low, bearing the potential of harmful N losses to environment, such as nitrate () leaching. To develop strategies increase NUE cattle slurry, a comprehensive understanding slurry dynamics in soil–plant system needed. In 57‐day microcosm experiment greenhouse, we assessed effect different treatments on turnover soil and its uptake ryegrass ( Lolium multiflorum...
