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 < 0.05) decreased the cumulative CO2 fluxes (by 47–64%)and N2O (by 62–77%) compared tothe other treatments containing inorganic fertilizer (F, Bc + F, Cmp + F) and significantly (P < 0.05) increased concentration of ammonium nitrogen in the soil by 16–21% as compared to treatments with organic fertilizers Cmp and Cmp + Bc. Our findings showed that the application of FBcCmp to the Haplic Luvisol presents environmental benefits to crop production, with the possibility for farmers to put higher concentrations of nutrients into the soil and restrict greenhouse gas emission from the soil.
