1. C And N Coupling Through Time: Soil C, N, And Grain Yield In A Long-term Continuous Corn TrialGains and losses of both C and N are important in agricultural landscapes. Temporal changes in the pattern of crop yield response to tillage and fertilizer input are commonly observed; often weakly interpreted, in long-term research. A 38-year-long monoculture corn (Zea mays L.) tillage (moldboard plow, no-tillage) by N rate (0, 84, 168, 336 kg N per hectare) trial was sampled to a depth of 100 cm, as was the surrounding... J.

2. Crop Rotation Impacts ‘Temporal Sampling’ Needed For Landscape-defined Management ZonesYield and landscape position are used to delineate management zones, but this approach is confounded by yield’s weather dependence, causing yield to evidence temporal variability/lack of yield stability. Management options (e.g. crop rotation) also influence yield stability. Our objective was to build a model that would describe the influence of crop rotation on the temporal yield stability of landscape defined management zones. Corn (Zea mays L.) yield data for two rotations,... E.M. Pena-yewtukhiw, J. Grove |
3. Six-Axis Robotic Arm and Object 3D Detection Technique for Supporting Mobility-Limited People on Grasping ObjectsThis paper presents the integration of a six-axis semi-industrial robotic arm with a real-time 3D object detection system to enable intuitive, contactless human-robot interaction, with a particular focus on healthcare applications. The robotic arm, powered by high-precision stepper motors, delivers enhanced accuracy and reliability compared to traditional servo-based systems, making it ideal for tasks that demand precision and consistency. The system is designed for extensibility, supporting... J. Chou |
4. Investigating the Behavior and Responses of Cage-free Laying Hens Using a Laser Disturbance SystemGrowing attention to animal welfare is accelerating the shift to cage-free housing, but floor eggs remain a persistent problem. Eggs laid on the ground are easily soiled, broken, and can transmit disease; they also raise labor and time costs because they must be collected quickly. Once floor laying becomes habitual, correction is difficult. We propose a laser-based disturbance system that uses non-invasive light cues to guide hens toward raised platforms and nest boxes. Deployed on an embedded... F. Chang |
5. Development of an Autonomous Navigation and Obstacle Avoidance Robot for Poultry ShedsTraditional poultry sheds in Taiwan are mostly open-structured, resulting in low efficiency for manual inspection and egg collection, and increased risks of labor fatigue and injuries. This study develops an autonomous obstacle avoidance system for unmanned agricultural vehicles tailored to poultry shed environments, focusing on dynamic path planning and obstacle evasion for safe, efficient navigation.A tracked vehicle chassis enhances stability and adaptability on soft litter floors and narrow...
