Meet the 4R Researcher Charlie Sanchez

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
