  • Managing waste from confined animal feeding operations in the United States: the need for sanitary reform

    Confined food-animal operations in the United States produce more than 40 times the amount of waste than human biosolids generated from US wastewater treatment plants. Unlike biosolids, which must meet regulatory standards for pathogen levels, vector attraction reduction and metal content, no treatment is required of waste from animal agriculture. This omission is of concern based on dramatic ...

  • CAFO Manure Treatment-Struvite Removal and Struvite Prevention

    CAFOs (Confined Animal Feeding Operations) face struvite in their manure holding ponds and manure lagoons, as well as their recirculation systems. On a dairy farm in Neb. that operated with 15,000 milking cows, they were generating 500,000 gal per day of wastewater laden with manure.  Over the summer, they noticed a reduction in their pumping capacity because the first lagoon was ...

  • Cultivating energy crop production

    A NEW Farm Bill is moving through the Congressional legislative process. Along the way, commercial agriculture is debating the energy impacts of future corn and soybean production. The growth of corn-based ethanol and soybean-based biodiesel has created competition for the feed inputs into animal agriculture, namely corn and soybeans. While most of agriculture discusses energy production from ...

  • Vermicompost’s Role in Farming

    One of the main goals of every organic farmer is to build long-term soil fertility and tilth by feeding the soil with a variety of natural amendments. The regular addition of compost is one of the best ways to enhance the soil’s organic and humic content, which helps to build a fertile soil structure. This soil structure makes better use of water and nutrients. It is easier to till and, ...
