Festivalgoers could be adding nitrogen and phosphorous to the rural environment at concentrated hotspots by weeing in the open air.

With the help of the microbes that once played an essential role in keeping you alive, the building blocks of your body go on to become a part of other living things.
There’s more to sustainability than net zero. Using green ammonia for fuel and as a way to transport hydrogen could add to nitrogen pollution that already exceeds safe planetary boundaries.
The inside of story of a pioneering programme to convert nitrogen into microalgae that can generate sustainable animal feed.
As environmental engineers, invasive caterpillars can have remarkable effects on water quality and soil conditions. But from a climate perspective they’re pretty much a nuisance.
Scientists have long thought most nitrogen in Earth’s ecosystems comes from the air, but new research shows it also is released as rocks weather. This could boost plant growth and help sequester carbon – but not fast enough to avert climate change, as some pundits have claimed.
Multiple reports have convincingly demonstrated that agroecology is the most promising pathway to sustainable food systems on all continents. But governments aren’t doing enough to support it.
Pollution has increased carbon in our soils - which is good for climate change. But this carbon may not stay there for long.
Somehow we need to grow more food to feed an expanding population while minimising the problems associated with nitrogen fertiliser use.
About 10% of human-generated greenhouse gas emissions come from farming. Researchers are working on ways to address this piece of the global warming puzzle.
