The FERT Foundation is home to 12 research projects that focus on fluid fertilizer and 4R optimization. Every week, we feature a different researcher in our publication. This week, we’re excited to introduce you to Charlie Sanchez.
Project Name: Spatial and Temporal N Management for Irrigated Vegetable Production Systems
University: University of Arizona
Years Funded: 2019-2021
4R Questions Addressed: Rate, Time and Place
This project focused on:
- Developing economically viable and effective sampling protocols to generate prescription maps for the variable rate pre-plant and in-season application of N comparing soil and plant sampling
- Comparing variable rate N application to current methods and evaluating alternative economic outcomes
- Evaluating and testing methods to augment zone-based management with optical sensors
