Title: Quantifying soil nitrogen dynamics in manured fields

Location: Multiple Locations within the state

Time Period: 2021 - 2022

Research Team: Sotirios Archontoulis, Marshall McDaniel, Peter Kyveryga and Scott Nelson

Project Description: The goal of this project is to enhance our understanding on soil N dynamics in manured fields via field experimentation and simulation modeling. Our objectives are:
1. Quantify soil N temporal dynamics in 30 manured fields spread across Iowa over two years (via field sampling) and subsequent years (via APSIM modeling).
2. Determine soil N immobilization/mineralization patterns and crop N availability from different manure sources and application timings.
