  • Evaluation of Soil Physical Properties as Influenced by Various Green Manuring Legumes and Phosphorus Fertilization under Rain Fed Conditions

    A field experiment was conducted under rainfed environment of Pothowar region of Pakistan to assess physical properties of soil as influenced by various green manure legumes (sesbania, cluster bean and rice bean) and different P levels (0, 30, 60, 90 kg P2O5/ha). Highest fresh biomass was observed in sesbania (23 t/ha) followed by cluster bean (19 t/ha) and lowest in rice bean (17 t/ha). Maximum ...

  • Soil and Water Benefits: Composting Reduces Fuel and Labor Costs on Family Farms

     Composting Reduces Fuel and Labor Costs on Family Farms Jeff and Pam Riesgraf — who manage a certified organic dairy and crop operation near Jordan, Minnesota — began composting manure from their dairy herd in 1993.

  • Latest Progress in Anaerobic Digestion

    Compared to countries like Germany and Denmark, the United States and Canada have a long way to go in creating the fundamental policy incentives and regulatory mandates that will encourage market development for anaerobic digestion (AD). Someone recently asked me how many years it would take to deploy AD systems on farms in North America that are large enough to economically use them. Given ...

  • Effect of maturation of Grease trap compost on plant growth

    Although it is known that immature composts can depress plant growth, few studies have quantified this effect in real-world scenarios with field-grown crops. Glasshouse and field trials were used to investigate the effect of maturation of grease trap compost (GTC) on plant growth. Grease trap waste was composted for 7-14 d in an in-vessel reactor with shredded green waste, sawdust and chicken ...

  • Improving soil nutrition with poultry litter application in low-input forage systems

    Despite high volumes of manure production in the Shenandoah Valley of Virginia, there are still areas of forage production that are nutrient deficient because manures have traditionally been applied to higher-value row crops. This study was conducted to compare the effects of poultry litter and inorganic fertilizers on soil fertility and forage production. Two sites had the same treatments ...

  • Financing an anaerobic digester

    LENDERS are generally well disposed to projects that diversify revenues while lowering costs and mitigating risks. Add a ready source of equity and you are well on the way toward financing a project that is a win-win proposition for the lender and the project developer. Such is the case with the anaerobic digester project at Geerlings Hillside Farm (GHF). The Geerlings's 8,000-head hog farm is ...

  • 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 ...
