Purdue Agronomy Farm Corn Moisture Stress (781801)
10.4231/R7J67DWZ
04/22/2015
The purpose of this experiment was to examine the effects of moisture stress on the reflectance and radiant temperatures of corn. The experiment was established on the Managed Soil Moisture System (MSMS). The MSMS facility is a series of plastic-lined plot...

Purdue Agronomy Farm Instrument Altitude (791811)
10.4231/R75T3HFN
05/05/2015
The object of the experiment is to determine how the canopy reflectance varies as a function of height above the crop and, particularly, what minimum height is needed to acquire repeatable reflectance measurements. Data were acquired on three canopies, mat...
