Research Project: MEASUREMENT AND MODELING PLANT WATER USE TO QUANTIFY NURSERY WATER REQUIREMENTS
2011 Annual Report


1a.Objectives (from AD-416)
The objectives of this cooperative research project are to.
1)apply aerial and substrate water measurement and modeling techniques,.
2)schedule nursery water use by integrating interactions between plant growth environment and recent advances in physiological process modeling of nursery water flux,.
3)move toward the development of a real-time model-sensor integrated system that calculates plant water use on a genotype specific basis, and.
4)move towards quantifying individual nutrient consumption and application across the growing season.


1b.Approach (from AD-416)
Measure inherent plant physiological responses and calculate physiological parameters. Develop process models for plant water use calculations. Simulate, forecast, and prescribe plant water use on a genotypic basis for selected containerized nursery crops under various irrigation schedules (volume and timing).


3.Progress Report

This project is related to Objective 2 of the in-house project: Effluent Water Quality.

The objective of this research project is to augment the inhouse research project by conducting research on a specific water irrigation control systems to promote water conservation and limit runoff. Work continues on developing species specific transpiration rates for optimizing irrigation efficiency to conserve water and to reduce runoff.

Progress was monitored by annual meeting, phone calls, and email communications.
