Agro-ecological intensification of continuous dryland wheat (Triticum aestivum L.) systems with forage soybean [Glycine max (L.) Merr] in lieu summer fallow could provide nutritious for livestock, reduce requirements inorganic N fertilizer winter wheat, and ameliorate sustainability issues associated fallow, such as soil erosion low precipitation use efficiency (PUE). This modeling study utiliz...

In this paper, we propose a robust watermarking scheme called Double-Layer Spread-Transform Dither Modulation (DL-STDM) for watermarking motion data. We embed watermarks into the DCT domain of the quaternion logarithm image (QLI) representation of motion data. Experimental results demonstrate that our scheme is more robust than existing motion watermarking schemes against a wide variety of atta...

For a cropping system to be sustainable, should not only the soil nitrogen (N) content be preserved but also the N runoff be minimised. Finding a simple but robust way to estimate N runoff would thus be a great advantage when evaluating cropping systems. In this study all major N flows in six different cropping systems, each covering 0.18 ha of a separately pipe drained field lysimeter, located...
