摘要
Prodn. of humus from ground bark, esp. conifer bark, comprises mixing with urea and composting with humus bacteria. The urea is pref. 0.5-1, esp. 0.8, kg. per cu.m. of bark. The process efficiently eliminates growth inhibitors present in the bark without the energy-intensive steam-treatment stage generally used.The urea allows composting to be carried out at high temp. and also supplies nitrogen in which the bark itself is relatively poor.
