Methods and protocols used in the collection of this data package

Description:

The Leaf Area Index (LAI) is a measurement of the amount of foliage in a plant canopy and is often incorporated into studies on primary production, water and nutrient use, carbon balance, and understory development. The LAI 2000 Plant Canopy Analyzer by LI-COR, Inc. calculates LAI from light measurements taken above and below the canopy with a "fish-eye" optical sensor which simultaneously measures light interception at five zenith angles. LAI is then computed using a model of radiative transfer and is reported as m2 m-2 (area of leaves per unit area of ground). In 2012, we started using an LAI AccuPAR LP-80 Ceptometer. In order to compare these measurements with those from the LAI 2000 Plant Canopy Analyzer, we made simultaneous measurements with both instruments, including across-row and along-row measurements for corn and soybean, in fall 2012 and throughout 2013. These data are available for comparison in the datatable at https://data.sustainability.glbrc.org/datatables/312. Frequency: depends on research purpose; we measured LAI every two weeks throughout the growing season in Block 1 (R1) for all treatments of the GLBRC Biofuel Cropping System Experiment (BCSE).
