Human waste could help combat global food insecurity

Researchers from Cornell University's College of Agriculture and Life Sciences and the Canadian Light Source (CLS) at the University of Saskatchewan have proven it is possible to create nitrogen-rich fertilizer by combining ...

How does an increase in nitrogen application affect grasslands?

The "PaNDiv" experiment, established by researchers of the University of Bern on a 3000 m2 field site, is the largest biodiversity-ecosystem functioning experiment in Switzerland and aims to better understand how increases ...

Ammonia has been missing in portraying air pollution impacts

Nitrogen is essential for all living things. Synthetic fertilizer, which contains rich reactive nitrogen, has sustained food production, but the nitrogen it emits is also a burden to the environment, such as air pollution, ...

Some domesticated plants ignore beneficial soil microbes

While domestication of plants has yielded bigger crops, the process has often had a negative effect on plant microbiomes, making domesticated plants more dependent on fertilizer and other soil amendments than their wild relatives.

Ecological fertilizer from wastewater nutrients

Wastewaters contain large amounts of phosphorus and nitrogen, which are valuable nutrients. Aalto University's NPHarvest process enables recovery of these nutrients as clean ammonium sulfate and sludge containing phosphorus ...

Consider soil in fall-applied ammonia rates, study says

Fall-applied anhydrous ammonia may not fulfill as much of corn's nitrogen needs as previously assumed. According to a new study from the University of Illinois, the effectiveness of the practice depends on the soil.

Coated seeds may enable agriculture on marginal lands

Providing seeds with a protective coating that also supplies essential nutrients to the germinating plant could make it possible to grow crops in otherwise unproductive soils, according to new research at MIT.
