Calculation of LAI and Interception of Short Canopies from First Growth Cover Measurments

From Decagon Devices, Inc.

First Growth was designed to measure the green cover of short, sparse plant canopies. The camera measures the fraction of its field of view that is green. If the camera views a vegetated surface from a position normal to the surface, then the fraction it measures is the green cover, c. With certain assumptions, this value can also be used to estimate the leaf area index, L, and the fractional light interception for a plant canopy. For short, sparse canopies, this approach is one of the few indirect methods available.

Tensiometers and Surface Tension Meters
Surface tension and wettability instruments measure fluid surface tension, a tangential force that keeps a fluid together at the air/fluid interface. Surface tension is a direct indicator of the quality of any chemical and any formulation.
Calorimeters and Thermal Analyzers
Calorimeters and thermal analyzers contain a heat source that can deliver a heat flux, at a distinct temperature, into a sample, and a temperature-measuring device that can read the resultant change in temperature.
Surface Area and Pore Size Analyzers
Surface area and pore size analyzers are used to measure the surface area and pore size of a sample.
Geophysical Instruments
Geophysical instruments are used for geological study, including rock and soil mechanics, core analysis and surveys of the earth.

The LP80 makes fast, direct measurements of photosynthetically active radiation in canopies. You get instant PAR measurements when you turn it on. You also get a measurement of leaf area index - LAI.

Leaf area index (LAI) is just a single number-a statistical snapshot of a canopy taken at one particular time. But that one number can lead to significant insight, because it can be used to model and...
