It's electric: Cows show promise as powerplants

... in a related experiment, the researchers used cow manure directly to create energy for a fuel cell. Using ... number of undergraduate students, used actual cow manure to power a microbial fuel cell. These individual cells produced between 300 and 400 millivolts. "Th...

Study shows eutrophic lakes may not recover for a millennium

... restoring wetlands and encouraging the use of new manure storage and handling processes are also steps that can be taken to reduce phosphorus runoff. "Anything we can do to reduce the erosion of phosphorus is going to be beneficial," Carpenter says. ...

Organic farms produce same yields as conventional farms

...lications with an organic animal-based farm (where manure was applied) and an organic legume-based farm (that used a three-year rotation of hairy vetch/corn and rye/soybeans and wheat). The two organic systems received no chemical fertilizers or pesticides. Inter-institutional collaboration included Rodale...

Wood fibre for papermaking goes throug...

Innocuous intestinal bacteria may be reservoir for resistance

...n-pathogenic, commensal bacteria isolated from cow manure contain the same antibiotic-resistance genes as those found in multi-drug resistant Salmonella strains found on the same farm. In addition, isolation of antibiotic-resistant Salmonella appears to be associated with whether or not commensal bacteria ...

Researchers develop technologies to devour food pathogens

...nt sanitary policies, as well as practicing better manure and water management, can go a long way to help prevent future outbreaks, Linton said. E. coli is especially problematic because it only takes as few as 10 cells to infect humans. Other pathogens, like salmonella, need thousands or millions of cell...

More recycling on the farm could reduce environmental problems

...It would also reduce overcropping and leakage from manure storage that contaminates groundwater. Yet despite similarities, Pearson's concept of regenerative agriculture is distinct from organic farming; for example, regenerative agriculture could use some chemically treated fertilizer and would exploit robo...
