Research Project: CERCA - On-Farm Nitrogen Recycling

Location: Plant, Soil and Nutrition Research

Project Number: 8062-21000-052-011-A
Project Type: Cooperative Agreement

Start Date: Oct 1, 2023
End Date: Sep 30, 2024

The objective of this research is to determine the potential impact of maintaining more N in maize fields on crop yield, resilience, and sustainability in the US under current and future climates (AIMS1 & 2). This is complemented by a gene and allele discovery pipeline that aims at reducing N in kernels (AIM 3), remobilizing N back to the roots (AIM 4) and understanding the relationship of variation in stover composition with nitrogen loss (AIM 5). By the end of year, we should have a clear effective modeling of these nitrogen traits from plant to farm, candidate genes and pathways identified across four trait areas, potential implications for policy, and a set of priority traits and strategies that can be advanced in future public and private partnerships.

The Cooperator will focus their research on AIM 2. The Cooperator will lead the impact assessment of Nitrogen traits to improve GHG emissions in current and future climates. The collaborator will use trained models for adaptive traits to assess the impact of single and combined traits and regions for improved adaptation climate change, various N x density x planting data management, and high C and N cycling.
