Research Project: MEASUREMENT AND MODELING OF SEASONAL PLANT WATER AND NUTRIENT USE TO DETERMINE OPTIMAL RATES FOR NURSERY PRODUCTION -WILLOWAY NURSERY

Location: Application Technology Research Unit

Project Number: 3607-21000-014-09
Project Type: Nonfunded Cooperative Agreement

Start Date: Sep 28, 2011
End Date: Dec 31, 2012

Objective:
Measure water and nutrient consumption over the course of two growing seasons; develop and refine mechanistic-based models that estimate and project optimum water and nutrient application rates across the growing season; apply, validate, and demonstrate the model performance in a closed loop system. Continue cooperation on smart sprayer testing including reduced pesticide rate/efficacy studies.

Approach:
Willoway will maintain the existing plot when it has been appropriately renovated. Willoway Nursery will ensure the system functions to automatically and continuously monitor and record the water quantity applied and leachate. Colorado State University cooperators will coordinate data collection, data analysis, and data presentation. Colorado State University cooperator's specific responsibilities will be outlined in a separate NFCA. ATRU engineers will also conduct basic spray application studies to reduce pesticide usage.
