Towards efficient N cycling in intensive maize: role of cover crops and application methods of digestate liquid fraction
<p class="MsoNormal"><span>Digestate, a by-product of biogas production, is widely recognized as a promising renewable nitrogen (N) source with high potential to replace synthetic fertilizers. Yet, inefficient digestate use can lead to pollutant N losses as ammonia (NH<sub>3</sub>) volatilization, nitrous oxide (N<sub>2</sub>O) emissions and nitrate (NO<sub>3</sub><sup>-</sup>) leaching. Cover crops may reduce some of these N losses and recycle the N back into the soil after incorporation, but the net effect on the N balance depends on the cover crop species. In a one-year field study, we tested the effects of two application methods (i.e., surface broadcasting, BDC; and shallow injection, INJ) of the liquid fraction of separated co-digested cattle slurry (DLF), combined with different winter cover crop options (CCs, i.e., rye, white mustard or bare fallow), as starter fertilizer for maize. Later in the season, side-dressing with urea was required to fulfill maize N-requirements. We tested treatment effects on yield, N-uptake, N-use efficiency parameters, and N-losses in the form of N<sub>2</sub>O emissions and NO<sub>3</sub><sup>-</sup> leaching. Cover crop development and biomass production were strongly affected by their contrasting frost tolerance, with spring-regrowth for rye, while mustard was winter killed. After the cover crops, injection of DLF increased N<sub>2</sub>O emissions significantly compared with BDC (emission factor of 2.69 <em>vs.</em> 1.66%). Nitrous oxide emissions accounted for a small part (11-13%) of the overall yield-scaled N losses (0.46 - 0.97 kg N Mg grain<sup>-1</sup>). The adoption of CCs reduced fall NO<sub>3</sub><sup>-</sup> leaching, <span>being 51% and 64% lower for mustard and rye than under bare soil. In addition, rye reduced </span>NO<sub>3</sub><sup>-</sup> leaching during spring and summer after termination by promoting N immobilization, thus leading to -57% lower annual leaching losses compared to mustard.<span> Our study confirms the potential of CCs to reduce </span>NO<sub>3</sub><sup>-</sup><span> leaching, but it also highlights that their residue can increase N losses once terminated and that they may cause yield reductions. DLF application method modified N-loss pathways, but not the cumulative yield-scaled N losses. Overall, these insights contribute to inform an evidence-based design of cropping systems in which nutrients are recycled more efficiently.</span></span></p>

Comparison of 2D and 3D Multichannel Audio Rendering Methods for Hearing Research Applications using Technical and Perceptual Measures - Impulse Responses and Scene Recordings
<p>This database contains recordings of impulse responses (IRs.zip) and virtual acoustic scenes (scenes.zip), with different 2D and 3D multichannel loudspeaker rendering methods. This upload contains conplementary data to [1].</p> <p>The virtual acoustic scenes are a 'concert' of an orchestra with approximately 60 primary sound sources [2] in a reverberant room, a 'speech' scene with a single talker in the same room, and a 'street' scene with static and moving sound sources.</p> <p>Recordings were performed with a G.R.A.S. 45BB Head and Torso Simulator (Kemar) placed in the center of the loudspeaker array in the lab, with ears at 1.60 m height. Recordings include the left and right ear channel. The simulator was equipped with large anthropometric pinnae of type KB5001. All recordings are provided for each rendering method that was applied in the study [1].</p> <p>Impulse responses were recorded using sine sweeps [3], sampling frequency was 44100 Hz. The impulse responses were truncated to 1.2 s. The scenes were recorded with a sampling frequency 44100 Hz.</p> <p> </p> <p>Files are named with the following convention:</p> <p>filetype_scene_renderingmethod_source.[mat/wav]</p> <p> </p> <p>References:</p> <p>[1] M.
