    Summary:

    Concentration of livestock and livestock waste requires disposal alternatives that are economically sound and environmentally safe.

    Objectives: To demonstrate justifiable economic response of crops when applying CMS compost versus conventional compost and piled manure. The coordinator planned to set up side-by-side composting trials with frequent turning, microbial innoculation, proper carbon-to-nitrogen ratios and daily monitoring of moisture and temperature versus typical turning procedures, all over six months. These two composts will be compared to each other and to piled manure for nutrient content, pH, weed seed viability, salts and pathogens.

    Results: Adverse weather conditions delayed implementation. The project was extended one year.
