Compost, manure and food waste can be turned into biofertilisers made from natural materials.
A labour and political ecology expert looks back at imperialistic logic and how chemical fertilisers have repeatedly served as strategic objectives and weapons, particularly in wartime.
Fertilizer is more expensive and in shorter supply. Without the right amounts of fertilizer at specific times, yields drop, food prices increase and food shortages result.
Despite claims of being humane and painless, the use of nitrogen gas for executions and assisted suicide causes air hunger, panic and violent physiological distress.
New research highlights the prevalence of maggots as an easily obtained, nutrient-rich supplement of ancient hominin diets.
The record-breaking and destructive forest fires of the summer of 2023 made headlines. But how did they affect the millions of lakes in the burned catchment areas?
Phosphorus and nitrogen contribute to water pollution and cause harmful algal blooms. New research shows how mats of floating flower beds can take advantage of these nutrients while cleaning the water.
While the Great Barrier Reed needs nutrients to support the ecosystem, it is possible to have too much of a good thing.
Pulses are important for many reasons. They are packed with nutrition, resilient and crucial for achieving food security in Africa.
Nutrient pollution fouls lakes and bays with algae, killing fish and threatening public health. Progress curbing it has been slow, mainly because of farm pollution.
Farmers are contending with huge spikes in fertilizer prices. The Biden administration is paying US companies to boost synthetic fertilizer production, but there are other, more sustainable options.
Cleaning up the Great Lakes was a big job when the US and Canada undertook it in 1972. Today it’s far more challenging.
The inside of story of a pioneering programme to convert nitrogen into microalgae that can generate sustainable animal feed.
Any climate gains from Japan’s shift will be wiped out entirely unless Australia moves to zero-emissions ammonia production.
Months not eating or moving don’t result in muscle wasting and loss of function for animals that hibernate. New research found gut microbes help their hosts hold onto and use nitrogen to build proteins.
If we want to reduce carbon emissions and preserve planetary ecosystems, we need to protect our soils.
Legumes have a superpower: they can convert nitrogen in the air into a form plants can use to grow.
A lack of policy has allowed industrial chicken farms to multiply in certain parts of the UK – with a lack of consideration of the environmental and social impacts.
Scientists need to know how much we can rely on the land to offset our emissions.
