The purpose of this experiment was to obtain data for crops other than corn, soybeans, and winter wheat which may have similar spectral characteristics. The other crops plots were those used by other researchers at the Agronomy Farm which were near the corn and soybean cultural practices plots and winter wheat plots. There was not much data collected for this experiment since its priority was lower than that for the other 1979 Agronomy Farm experiments. The other crops included alfalfa and sunflowers.
The spectral measurements were made with a Landsat band radiometer (Exotech Model 100) and the Exotech 20C field spectroradiometer field system. Minimal agronomic data were collected on the plots.

The test took place in 1979.
The supporting docs include a brief summary of used instruments, a wavelength table (Wavelength_ASCII.txt), reflectance note and reflectance tables (ReflectanceTable206.txt and ReflectanceTableMulti.txt), and file format description (ExperimentDataFormat3.txt). The format description file is in ASCII format in lines of 80 characters.
This research dataset is part the Field Research Data Library that consists of over 200,000 spectral observations of soils and vegetation that have been collected since 1972 till 1991 as part of the research focused on vegetation and soils at the Laboratory for Applications of Remote Sensing (LARS) located at the Purdue University.
