Purdue Agronomy Farm Soybean, Potassium, and Phosphorous (781804)
10.4231/R75X26VZ
04/21/2015
The purpose of this experiment was to examine the effects of different levels of soil phosphorous and potassium on the reflectance and radiant temperatures of soybeans. Plots for data collection were selected from a long term experiment. Measurements of...

Purdue Agronomy Farm Soybean Row Direction (791810)
10.4231/R7222RQ7
05/04/2015
The objective of the experiment is to determine the effect of rows and row direction, variables in the area of cultural practices, on the reflective response of a soybean canopy as a function of azimuth and zenith sun angles. The design of the experiment i...

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...
