Influence of wood biochar of phenanthrene castbolism in soils - Vol.19(1), Jan-Jun - New Delhi Serials Publications 2022 - 11-24p.
The impact of increasing amendments of two particle sizes (<_2 mm and 3-7 mm), applied at 0%, 0.01% and 1% concentrations, on the development of indigenous phenanthrene catabolism was investigated in two soils with different soil organic matter contents. Mineralisation of 14C-phenanthrene was measured after 1, 20, 60 and 100 d soil-phenanthrene-biochar aging period. The presence of biochar in the pasture soil (low OM) resulted in a decrease in the lag phase of 14C-phenanthrene mineralisation, with higher maximum rates of minneralisation following 20 d aging. Higher extents of 14C-phenanthrene mineralisation were observed in the kettering loam soil .
