This project, developed under Phase 2 of Can Tho University's Technical Support Project, introduces an advanced integrated platform featuring a soil nutrient and greenhouse gas monitoring system specifically designed for Alternate Wetting and Drying (AWD) rice cultivation. To drive sustainable agriculture in the Mekong Delta, the infrastructure utilizes automated wireless sensor networks alongside handheld smart devices to monitor water levels, soil N-P-K, pH, salinity, and $CH_4$/$N_2O$ emissions in real-time. The technical framework is seamlessly coupled with a dedicated application layer that allows agricultural experts to define high-quality farming models, outline production tasks, and systematically track resource utilization using Gantt charts. This holistic digital approach effectively empowers farmers to manage fields remotely, maintain thorough electronic production logs with image uploads, reduce chemical inputs, and accurately quantify environmental footprints to verify emission reductions.
