Radiation sources must be treated separately in the computation of leaf area index from canopy transmission measurements.
Recalibrate every three years for the highest accuracy.
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.
The processes in photosynthesis are complicated and hard to model. But, it’s possible to simplify the model by focusing on one or more of the limitations.
The LP-80 gives instant PAR measurements when you turn it on, and it also provides a measurement of Leaf Area Index–LAI. But where does this LAI measurement come from, and how accurate is it?
Riparian strips shade streams when timber is harvested or prescribed burns are undertaken. Determine how much shade and what size of strips are needed.
Good irrigation management requires the answer to two questions: when do I turn the water on, and when do I turn it off?
