J %A Olesen, J. E, Morvan, T %K EPNB %X The processes of NH3 emission from field-applied slurry are reviewed and their relative importance assessed. In achieving this objective, the study served to focus on a number of features that have not previously been highlighted. These include the effect of the size of the area to which slurry is applied, the interaction between solar radiation input and wind speed, the role of the solid chemistry and the interaction between slurry NH4 and the slurry/soil cation exchange capacity (CEC). The most important processes controlling NH3 volatilisation were considered to be turbulent and molecular diffusion in the atmosphere, meteorological processes controlling evaporation and surface temperature, the ion production and buffering processes controlling the pH of the slurry/soil liquid, the solid chemistry that determines precipitation of NH4 to slurry dry matter, the physical processes controlling the movement of slurry liquid into and within the soil, and the interaction of slurry liquid with soil CEC. %B European Journal of Agronomy %V 19 %P 465-486 %1 EPNB %0 Journal Article %J Nature Sustainability %D 2018 %T {The potential of future foods for sustainable and healthy diets} %A Parodi, Alejandro %A Leip, Adrian %A De Boer, I.

E. %X Altering diets is increasingly acknowledged as an important solution to feed the world's growing population within the planetary boundaries. In our search for a planet-friendly diet, the main focus has been on eating more plant-source foods, and eating no or less animal-source foods, while the potential of future foods, such as insects, seaweed or cultured meat has been underexplored. Here we show that compared to current animal-source foods, future foods have major environmental benefits while safeguarding the intake of essential micronutrients. The complete array of essential nutrients in the mixture of future foods makes them good-quality alternatives for current animal-source foods compared to plant-source foods. Moreover, future foods are land-efficient alternatives for animal-source foods, and if produced with renewable energy, they also offer greenhouse gas benefits. Further research on nutrient bioavailability and digestibility, food safety, production costs and consumer acceptance will determine their role as main food sources in future diets. %B Nature Sustainability %I Springer US %V 1 %P 782–789 %G eng %U http://dx.doi.org/10.1038/s41893-018-0189-7 http://www.nature.com/articles/s41893-018-0189-7 %R 10.1038/s41893-018-0189-7
