  • Sorption, uptake and biotransformation of 17β‐estradiol, 17α‐ethinylestradiol, zeranol and trenbolone acetate by hybrid poplar

    Hormonally active compounds may move with agricultural runoff from fields with applied manure and biosolids into surface waters where they pose a threat to human and environmental health. Riparian zone plants could remove hormonally active compounds from agricultural runoff. Therefore, sorption to roots, uptake, translocation, and transformation of three estrogens (17β‐estradiol, ...

  • A cost-effective method for controlling compost air emissions

    In October 2007, ECS began conducting trials at California State University Fresno (CSUF) to explore using the new patent pending AC Composter (ACC) covered aerated static pile system to manage dairy manure solids and comply with airquality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF research dairy. This research is being conducted under a Phase I ...

  • 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 — ...

  • Building a Business with Nutrient Management

    Laurelbrook Farm is a third-generation dairy farm in East Cannan, Connecticut. The Jacquier family owns 275 acres, and rents an additional 2,500 acres for cropping, to support a herd of 830 cows. The family began composting three years ago as part of the farm’s nutrient management plan, as well as to determine the market for compost in the area. “In 2003 the Environmental Protection ...

  • Effect of tillage and nitrogen rate on corn yield and nitrogen and phosphorus uptake in a corn-soybean rotation

    Understanding tillage, N, and P interactions can contribute to improved N and P utilization and crop response. This study examined the interaction effects of tillage and N rate of two N sources on N and P uptake by corn (Zea mays L.). The study was conducted on Kenyon loam (fine loamy, mixed, mesic Typic Hapludolls) soil at the Iowa State University Northeast Research and Demonstration Farm near ...

  • 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 ...

  • 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 ...

  • Transition from intensive tillage to no-tillage and organic diversified annual cropping systems

    Transition to no-till (NT) and organic (ORG) farming systems may enhance sustainability. Our objectives were to compare transitional crop productivity and soil nutrient status among diversified NT and ORG cropping systems in Montana. Three NT systems were designed as 4-yr rotations, including a pulse (lentil [Lens culinaris Medik.] or pea [Pisum sativum L.]), an oilseed (canola [Brassica napus ...

  • Transition of fertilizer application and agricultural pollution loads: a case study in the Nhue-Day River basin

    Rapid socio-economic development in suburban areas of developing countries has induced changes in agricultural waste and nutrient management, resulting in water pollution. The study aimed at estimating agricultural nutrient cycles and their contribution to the water environment. A material flow model of nitrogen (N) and phosphorus (P) was developed focusing on agricultural activities from 1980 ...

  • Phosphorus And Compost Use Dynamics

    Organic forms of phosphorus, such as biosolids and compost products, contain low to very low levels of water extractable phosphorus, but increasingly are regulated like inorganic P sources. Phosphorus is one of the 16 essential plant nutrients, and is considered one of the three major plant nutrients (along with nitrogen and potassium). Phosphorus is not only important in root development, but ...

  • Florida Dairy Succeeds With AD System

    North Florida dairy with 6,100 mature cows and 5,500 replacements installed anaerobic digestion system that is yielding multiple benefits. Dairy farming in Florida has financial and logistical challenges, including hot, humid summers; high electrical costs; access to fresh water; odor; greenhouse emissions and sandy soil issues. Alliance Dairies in Trenton, Florida has found sustainable ...

  • Certified Organic Farm Relies on Compost

    Located 50 miles northwest of Dayton, Ohio, the owners of Fresh Aire Farms grow crops on over 250 acres of farmland, relying on high quality compost as a soil conditioner and nutrient amendment. Dan and Michelle Young started composting seven years ago to reduce the amount of chemical inputs they had to buy. “We are a certified organic farm incorporating sound cropping principles,” says Dan ...

  • Consequences of conventional versus organic farming on soil carbon: results from a 27-Year field experiment

    Organic farming practices are regarded as being beneficial for the environment by promoting soil quality and sequestering soil organic carbon (SOC). We studied SOC dynamics in the long-term field experiment DOK in Switzerland. The experiment compares three organically fertilized treatments under conventional (CONFYM), bioorganic (BIOORG), and biodynamic (BIODYN) management, and two systems with ...

  • Dairy Digester Opens Doors On Maryland Farm

    Kilby Inc., a 600-cow dairy operation located in Colora, Maryland, has the only operational commercial anaerobic digestion (AD) system in the state. In 2009, Kilby Inc. (the dairy farm and milk production business) began construction of a covered lagoon digester, which started operating in March 2011. The digester input consists of flushed cow manure (98% by volume) and food waste (2%), including ...

  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...

  • 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 ...
