Improving performance and expanding application of denitrifying bioreactors for nutrient management in agricultural landscapes
… 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 to …

Simulation of urea particle flow using DEM for dry fertilizer spreading optimization
… 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 pertinent to fertilizer spreader applications. Urea was first …
