This study tested the effects of soil amendment with two loads of wood-derived biochar (30 and 60 t ha(-1)) in a wheat crop in Tuscany (Italy). Soil samples were collected 3 and 14 months after treatments over two successive growing seasons, and analysed for pH, total organic C (C-org), extractable C (C-ext), microbial biomass-C (C-mic), 25 specific microbial activities, mean substrate-induced respiration (mSIR) for 25 substrates, functional microbial diversity and bacterial genetic diversity. No significant effect of biochar treatment was observed on C-org, C-ext, C-mic, microbial quotient (C-mic % C-org) or genetic diversity. An increase in mSIR, some specific microbial activities and soil pH, and a significant change in functional diversity were observed 3 months after treatment. In contrast, no effect of biochar was detected 14 months after treatment for the parameters considered, except for a small but significant increase in pH. Our data suggest that biochar addition stimulated soil microbial activity without causing any apparent disturbance, but this positive effect was very short-lived.

For the simulation study, eight treatments of combinations of conventional tillage (CT) or no-till (NT), stubble burning (SB) or stubble retention (SR), and N fertiliser application at nil (0N) or 90 (90N) kg N/ha.year were used. The results indicated that WNMM satisfactorily simulated the soil water content of the topsoil, mineral N content of the entire soil profile (0\uffe2\uff80\uff931.5\uffe2\uff80\uff89m), and N2O emissions from the soil under the eight treatments, compared with the corresponding field measurements. For simulating daily N2O emissions from soil, WNMM performed best for the treatment CT-SB-90N (R2\uffe2\uff80\uff89=\uffe2\uff80\uff890.48, P\uffe2\uff80\uff89&lt;\uffe2\uff80\uff890.001; RMSE\uffe2\uff80\uff89=\uffe2\uff80\uff8910.2\uffe2\uff80\uff89g N/ha.day) and worst for the treatment CT-SB-0N (R2\uffe2\uff80\uff89=\uffe2\uff80\uff890.03, P\uffe2\uff80\uff89=\uffe2\uff80\uff890.174; RMSE\uffe2\uff80\uff89=\uffe2\uff80\uff891.2\uffe2\uff80\uff89g N/ha.day). WNMM predicted N2O emissions from the soil more accurately for the fertilised treatments (i.e. 90N v. 0N), and for the residue retained treatments (SR v. SB). To reduce N2O emissions from the no-till and fertilised treatments, three scenarios were examined: application of nitrification inhibitor, application of controlled-release fertiliser, and deep placement of liquid fertiliser (UAN32). Only the deep placement of UAN32 below the 35\uffe2\uff80\uff89cm depth was effective, and could reduce the N2O emissions from the soil by almost 40%.</p>", "keywords": ["2.
