  • Cow-pattie power

    On a massive cattle feedlot located outside the town of Vegreville, Alta., the pungent odour of cow manure is masked by the sweet smell of the province’s energy future. Turning cattle dung — “brown gold,” as some call it — into green power and other valuable byproducts is a made-in-Alberta energy solution that is not only sustainable and energy efficient, but also ...

  • 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 ...

  • 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 ...

  • Compost Users Forum: The Applied Thoughts Of A Compost Theorist

    WITHIN a 60-mile radius of my office here in central California, there are 1,000 dairies — each having an average of 2,000 cows. They generate over four million tons of manure annually, so we are pretty much in the manure business whether we want to be or not. Somebody has to manage this material and help the farmers utilize it properly, fulfilling its potential monetary value. That’s what we ...

  • Redefining ag-wastes as coproducts

    Alan Doering doesn’t have the word “waste” in his vocabulary. As the scientist heading up the Agricultural Utilization Research Institute’s (AURI) coproduct utilization program, Doering sees crop residue, agricultural processing leftovers and biomass as products with value worth exploring. “Every leftover or coproduct has a value,” Doering says. “Our goal is to find the best use with the highest ...

  • Industry Takes Shape: Why Digesters Make Dollar Sense Now

     THIRTY years ago, when I was a college student studying ways to convert manure to electricity, we speculated that the 1970s would be the decade of the innovators, the 1980s for the launch of operating projects, and the 1990s when the mainstream adopted the technology. Now I think our predictions for the mainstream were ten to 15 years premature — but it is happening! During the 1990s, the ...

  • Adding Value To On-Farm Digesters

    ANAEROBIC digestion of dairy manure and food processing residuals in Michigan is not a new undertaking. Over the years, 11 farm digesters were constructed in the state, of which four are still operational, reports Michelle Crook of the Michigan Department of Agriculture in a presentation in the spring of 2007. “Three of the operating digesters are for livestock manure and one is for food ...

  • Creating a Sustainable Food Future: Interim Findings - A menu of solutions to sustainably feed more than 9 billion people by 2050

    The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who depend on agriculture for their livelihoods, and reduce environmental impacts, including ecosystem degradation and ...

  • Beef Farmer Spring 2017 `Trace elements are key to growth rates`

    Iodine has a direct impact on growth rates as it is incorporated into the thyroid hormones which control metabolism, promoting efficient live weight gain. Annie Williams, Animal Scientist with Agrimin says that many beef units fall short on achieving optimum growth rates because animals do not receive adequate levels of trace elements at grass. She says that with increased feed costs, many ...

  • Compost science journal of advocacy and foresight

    SEVERAL months ago, I started on a journey through the pages of Compost Science, beginning with the Spring, 1960 inaugural issue. I was confident that I could whip through the articles and news items in the several hundred issues of the magazine between 1960 and 2009, and be prepared to write this article for BioCycle’s 50th Anniversary Commemorative Edition. Granted, there were interruptions, ...
