  • A four‐country ring test of nontarget effects of ivermectin residues on the function of coprophilous communities of arthropods in breaking down livestock dung

    By degrading the dung of livestock that graze on pastures, coprophilous arthropods accelerate the cycling of nutrients to maintain pasture quality. Many veterinary medicinal products, such as ivermectin, are excreted unchanged in the dung of treated livestock. These residues can be insecticidal and may reduce the function (i.e., dung‐degradation) of the coprophilous community. In the present ...

  • Clean, green and powered by cow patties

    Two dome-like structures rise out of the thick ice fog of a Prairie winter day. From a distance, a science-fiction city seems to be taking shape on the rolling grasslands of east-central Alberta. Then, as you draw near, another sensation takes hold – the oppressively pungent odour of cow manure. On this day, the enveloping fog is making the smell worse than usual, explains Bern ...

  • Closed loop system takes manure and methane

    A CONVERSION plant in Mead, Nebraska is processing manure and methane to create ethanol and compost. According to Nebraska Governor Dave Heineman: “This plant sets a new standard for ethanol production in this state and our nation, and is an example of the innovation needed to take this industry to the next level. It lets America get its automotive fuel from the croplands of the Midwest instead ...

  • Tapping the potential of codigestion

    Codigestion refers to processing multiple biodegradable substrates (feedstocks) in an anaerobic digestion (AD) system. A more contemporary definition refers to the digestion of a combination of select biodegradable feedstocks with a base substrate that an AD system was designed to handle. The intent is to maximize the production of biogas (i.e., renewable energy) by adding substrates that produce ...

  • Composting In rural Alaska

    Gardeners, communities and commercial enterprises have proven that composting works in Alaska, especially given large quantities of fish waste and diminishing landfill capacity. ALASKA is two and a half times larger than the largest state in the lower 48 states. Over half of the entire state’s population lives within the municipality of Anchorage. Many Alaskan villages can only be reached ...

  • Does one of the world’s most abundant animals need protection from our appetite?

    As demand grows and habitat disappears, scientists ponder tighter controls on the Antarctic krill harvest. Barely longer than your thumb, weighing under an ounce and nearly translucent, delicate crustaceans known as krill are vital to ocean ecosystems around the world. In the waters that encircle Antarctica, krill are an essential food source for penguins, baleen and blue ...

  • Impact of Agri-environment measures

    The application of agri-environment contracts concerning 1 farmer in every 7 and delivering environmental services over 20% of European farmland, marks a very significant step towards sustainability. The target set in the 5th Environmental Action Programme of 15% coverage by 2000 has thus already been exceeded. The requirement on Member States to apply the regulation throughout their territories ...

  • Cost-Benefit Analyses: Exploring the Economics of On-Farm Composting

    When exploring the merits of on-farm composting, the question most often raised is: What are the economics? How do the savings or revenues from on-farm composting compare to the costs? Of course, the answer is the ever present “it depends.” Expenses, resources, revenue opportunities, environmental constraints and circumstances vary greatly from one farm to the next. Most people would agree that ...
