The Expert Guide to Leaf Area Index: Theory, Methods, and Application

The expert guide to leaf area index: theory, methods, and application

Plant physiologist Jeff Ritter explains the practical application of Leaf Area Index and how this measurement will transform your research.

The ins and outs of LAI

Leaf Area Index (LAI) has vast implications across land use management, ecology, and any project impacted by gross primary productivity (GPP). But multiple measurement methods make the process of choosing the best method for your application confusing. How do you balance accuracy and labor efforts? Join us February 27th, 2024 at 9am PST to find out.

In this webinar, METER’s Product Manager for plant, canopy, and atmospheric monitoring, Jeff Ritter, will discuss:

  • What is LAI?
  • Why measure LAI?
  • Direct sampling methods, including litter traps
  • Indirect ground-based methods, including hemispherical photography
  • The difference between transmittance and reflectance methods
  • Satellite-based approaches
  • How to choose the right method for your project that balances precision and labor intensity

Jeff Ritter is the Product Manager for plant, canopy, and atmospheric monitoring instrumentation here at METER. He earned his master’s degree in plant physiology from Washington State University, where his research focused on leaf-level gas exchange, and the impact of plant biochemistry on the measurement of the global carbon cycle. Prior to working at METER, he held a research faculty position at Washington State University in the Department of Crop and Soil Sciences.

Leaf Area Index (LAI): The Researcher’s Complete Guide

Leaf area index is a single number–a statistical snapshot of a canopy taken at one particular time. But that one number can lead to significant insight.


Radiation Resource Capture: Are You Leaving Yield On The Table?

Four resources need to be plentiful within a crop’s environment to increase biomass: CO₂, water, nutrients, and PAR. In this webinar, Dr. Campbell dives deep into the measurement and implications of PAR.


How to use PAR for more efficient irrigation

Good irrigation management requires the answer to two questions: when to turn the water on and when to turn it off.
