Energy from microbes for drying sewage sludge

A new biodrying process from Siemens quickly converts sewage sludge into a usable form while saving energy. When dried with the new process, sludge from wastewater treatment can be used as fertilizer, dumped in landfills ...

Using wastewater as fertilizer

Sewage sludge, wastewater and liquid manure are valuable sources of fertilizer for food production. Fraunhofer researchers have now developed a chemical-free, eco-friendly process that enables the recovered salts to be converted ...

Friends with benefits: Study finds insects aid in moss sex

(Phys.org) -- Researchers at Portland State University have discovered how mosses can use chemical cues to recruit small creatures to help with fertilization, via a process similar to pollination in flowering plants.

Thawing permafrost increases fertility in subarctic peatlands

(Phys.org) -- A group of ecologists from Umea University's Climate Impact Research Centre (CIRC) and VU University Amsterdam have shown that thawing permafrost increases fertility in subarctic peatlands in northern Sweden. ...

A genetic alternative to fertilizer

Several studies have shown that a lack of nitrogen in soils adversely affects crop yields. The modern use of nitrogen fertilizers has improved yields to meet expanding global food demand, but in some cases up to 50% of the ...

Plant diversity is key to maintaining productive vegetation

Vegetation, such as a patch of prairie or a forest stand, is more productive in the long run when more plant species are present, a new University of Minnesota study shows. The unprecedented long-term study of plant biodiversity ...

Gene expression reveals how potatoes are cultivated

Organically grown potatoes have a higher gene expression of starch production than conventional ones. This statement is put forward by RIKILT, part of Wageningen UR, researcher Jeroen van Dijk, who can tell organically grown ...
