  1. Improving performance and expanding application of denitrifying bioreactors for nutrient management in agricultural landscapes

    Subsurface tile drainage is widely implemented across agricultural landscapes in the U.S. Midwest, creating direct hydrologic pathways that transport excess nutrients from fields to surface waters. As a result, nitrate (NO₃) can bypass natural soil filtration and attenuation processes, contributing …

  2. Simulation of urea particle flow using DEM for dry fertilizer spreading optimization

    Uniformity of dry fertilizer spread pattern relies on the accurate representation of bulk material behavior during handling, discharge, and impact. This study aims to develop a discrete element method (DEM) model for urea and assessed it through a calibration and multi-method validation framework …

  3. Autonomous Multi-Sensor and Web-Based Decision Support for Crop Diagnostics in Greenhouse

    An autonomous machine vision guided plant sensing and monitoring system was designed and constructed to continuously monitor plant related features: color (red-green-blue, hue-saturation-luminance, and color brightness), morphology (top projected canopy area), textural (entropy, energy, contrast, …
