| Popis: | The effect of a nitrogen enriched biochar mixed with compost (FBcCmp) in ratio 50:50 v/v on carbon dioxide (CO2) and nitrous oxide (N2O) emission from Haplic Luvisol was studied in a laboratory experiment. Biochar was produced from grain husks and paper fiber sludge and enriched with 10% ammonium sulfate solution; compost was generated from green waste, milk sludge and stone powder. Eight treatments were used in the experiment: control (Co), biochar (Bc), compost (Cmp), 10% ammonium sulfate solution(F) and their mixtures: Bc + Cmp, Bc + F, Cmp + F, and FBcCmp, which were applied to the soil at two rates equal to10 and 20 t ha−1(rate I and II), respectively. Direct fluxes of CO2 and N2O from the mesocosms were measured using the closed chamber technique. Application of FBcCmpin both rates significantly (P |
