Part 4: Irrigation of Controlled Environment Crops for Increased Quality and Yield

undefined

If you’re not measuring the right variables, fixing problems that keep you from your goals will be a shot in the dark, because you won’t know what the real problem is.

PART 4: BALANCING LIGHT, WATER, AND NUTRIENTS

 

Are you unwittingly compromising your plants?

In a controlled environment many variables affect production. But if any one of those variables gets out of balance, it can undermine your whole operation. For example, if you apply enough nutrients for high production but only enough light for low production, you’ll increase costs and limit yield. To get the most out of your crop, you’ll need to measure and balance environmental inputs correctly to get the most efficient use out of them. If you’re not measuring the right variables, fixing problems that keep you from your goals will be a shot in the dark, because you won’t know what the real problem is.

Amplify your production and efficiency

In part 4 of our popular controlled-environment webinar series, world-renowned soil physicist, Dr. Gaylon Campbell, teaches what is required to ensure all environmental variables remain balanced for the highest possible efficiency and production. Discover:

  • How to model biomass production from light, water, and nutrient resources
  • Relationships between biomass production, light, and CO2
  • Relationships between  biomass production and water use
  • Relationships between biomass production and nutrient uptake 
  • Limiting factors in the balance equations 
  • Examples and monitoring applications

Presenter

Dr. Gaylon S. Campbell has been a research scientist and engineer at METER for over 20 years, following nearly 30 years on faculty at Washington State University. Dr. Campbell’s first experience with environmental measurement came in the lab of Sterling Taylor at Utah State University making water potential measurements to understand plant water status.

Dr. Campbell is one of the world’s foremost authorities on physical measurements in the soil-plant-atmosphere continuum. His book written with Dr. John Norman on Environmental Biophysics provides a critical foundation for anyone interested in understanding the physics of the natural world. Dr. Campbell has written three books, over 100 refereed journal articles and book chapters, and has several patents.
