  • Composting Feedlot Manure

    Situated in the Texas panhandle is an area known as the Rolling Plains ecological region, a topography consisting primarily of open-range pasture and cropland. Approximately one-third of the Rolling Plains region is dedicated to production agriculture, where huge fields of wheat, cotton and sorghum extend into the distance for as far as the eye can see. The remaining area is native grassland, ...

  • Compost, manure and synthetic fertilizer influences crop yields, soil properties, nitrate leaching and crop nutrient content

    From 1993 to 2001, a maize-vegetable-wheat rotation was compared using either 1) composts, 2) manure, or 3) synthetic fertilizer for nitrogen nutrient input. From 1993 to1998, red clover (Trifolium pratense L.) and crimson clover (Trifolium incarnatum L.) were used as an annual winter legume cover crop prior to maize production. From 1999 to 2001, hairy vetch (Vicia villosa Roth.) served as the ...

  • Dietary cation–anion difference and tetany index of timothy forage fertilized with liquid swine manure

    Incidence of metabolic disorders increases when dairy cows (Bos taurus) are fed forages that have a high dietary cation-anion difference (DCAD) (>250 mmolc kg–1 dry matter, DM) or high grass tetany (GT) index (>2.2), both associated with high forage K concentration, often caused by applications of liquid swine manure (LSM). We determined how DCAD and GT index of timothy (Phleum pratense L.), ...

  • Dutch Farmers Find It Pays To Manage Poultry Manure

    Poultry farmers in Holland face challenges similar to their North American counterparts in dealing with manure from concentrated operations where there is insufficient cropland for application. This creates a need for exporting manure from the producing farm to users in other places. Poultry operations in Holland differ from most North American poultry farms in that most are not vertically ...

  • Evaluation of compost for use as a soil amendment in corn and soybean production

    The purpose of this research project was to 1) evaluate rate of compost application and 2) to compare compost with uncomposted raw material and inorganic fertilizer N application upon maize and soybean growth and productivity, and upon soil characteristics. During the first three years of the study, the source of uncomposted material and compost was food waste and ground newsprint. During years 4 ...

  • The effect of different percentages of bulking agent (sawdust) on microbial quality of faecal sludge

    The use of raw sludge spread on land as conditioner and fertilizer has been practised over the years in urban agriculture. However, this raw sludge (biosolids) is associated with a potential health risk as a result of the pathogenic microorganisms it contains. The study considered the dewatering of faecal sludge (FS) mixed with sawdust to produce biosolids that can be applied as manure for ...

  • 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 ...

  • Sustainable Soil Health

    “A Nation that destroys its soil destroys itself.” – Franklin D. Roosevelt. We have learned some harsh lessons about how to treat our soil. While most of us are aware of the problems of the past, some agricultural operations in the world are not heeding those lessons. We all know that healthy soil is essential to feed the ever-increasing ...

  • Implementing Research : Georgia Takes Many Routes to Recycle Food Residuals

     PETROLEUM HYDROCARBON LEVELS “One unique local characteristic (and treatment difficulty) we encountered in our composting program,” says Stan Konno, PWC environmental department director head, “is the high level of diesel range total petroleum hydrocarbon (TPH) content in the sludge from the WWTF at Fort Kamehameha.” Oil from past leaks in pipelines and tanks — which go back to 1941 — ...

  • 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 ...

  • 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 ...

  • Composters Build Strong Links to California Farms

    The rapidly increasing amounts of compost applied to California farms can be traced to numerous factors — better crops, fewer disease problems, greater emphasis on product quality, mandated state recycling goals, savings in disposal costs and savings in chemical inputs. And then there’s the factor of friendship, longtime personal relationships that build trust between composters and farm ...

  • 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, ...

  • State Of Composting In The U.S.

    The benefits of composting are well documented. Compost is a valuable soil conditioner. It adds needed organic matter, sequesters carbon, improves plant growth, conserves water, reduces reliance on chemical pesticides and fertilizers, and helps prevent nutrient runoff and erosion. Composting also reduces the volume of materials that might otherwise be disposed in landfills or trash incinerators, ...
