Instead of closing down in the face of community opposition to its environmental ...


  • Compost maturity as expressed by phytotoxicity and Volatile organic acids

    VOA in Composts Maturity is a qualitative trait of compost that may be expressed in a number of ways and is generally held to be relevant to plant performance. Volatile organic acids (VOA) have been cited to be responsible for phytotoxicity (plant growth suppression) when immature compost is used for growing plants (Manios et al., 1989). However, the production of VOA in compost has not been well ...
