Project Summary

This project will explore how individual and stacked nutrient and irrigation 4R’s intersect to improve the sustainability of major forage, fruit, grain, and vegetable crops in the West. It will address both priority cropping systems and priority issues outlined in the request for proposals. Four major efforts will include producer surveys to quantify 4R adoption and barriers, five coordinated field experiments that will utilize a new innovative way to evaluate stacking nutrient 4R’s across crops, utilization of three existing stacked irrigation 4R experiments to quantify how 90 water conservation treatments influence nutrient uptake and efficiencies, and a dynamic multi-state coordinated outreach program to improve adoption of nutrient and irrigation 4R’s. Intersecting nutrient and irrigation 4R’s will guide investments by growers and industry towards combinations that result in the most profitable and sustainable outcomes

Project Goals:

  • Determine western forage, fruit, grain, and vegetable producer’s attitudes, acceptance rates, and barriers to adoption of nutrient and irrigation 4R’s in order to better adapt and target Extension and outreach efforts.

  • Identify how individual and stacked nitrogen fertilizer 4R’s impact crop performance, water productivity, and environmental impacts.

  • Expand FFAR trials to determine how individual and stacked irrigation 4R’s impact nutrient uptake and use efficiency.

  • Deliver dynamic educational products and training on nutrient and irrigation 4R’s through Extension and coordinated outreach.

Project Results:

  • No preliminary results
