Part 3: Irrigation of Controlled Environment Crops for Increased Quality and Yield

Get the information you need to stress or de-stress your crop at the right time and in the right way to achieve your goals.

Part 3 : Calculating water requirements

 

Grow your crop steering expertise

Crop steering can optimize crop production and production costs, but to crop steer successfully, you need to do it right. You have to understand how to obtain the right soil water contents and soil electrical conductivities to either stress the crop or avoid stressing the crop in a controlled way. To do this, you’ll need to perform crop steering calculations.

Steer your way to higher quality, productivity, and profit

In part 3 of our greenhouse webinar series, Dr. Gaylon Campbell, internationally recognized soil physics and environmental measurement expert, teaches how to perform crop steering calculations that give you the information you need to stress or de-stress your crop at the right time and in the right way to achieve your goals. In this 30-minute webinar you’ll learn:

  • The water balance equation
  • How to calculate the irrigation amount
  • How to calculate the transpiration variables that affect recharge drainage, and changes in stored water
  • How to determine the field capacity of the substrate
  • Environmental factors that influence the water balance
  • How to determine the leaching fraction
  • How to manage substrate electrical conductivity

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.
