A Chamber for Controlling High Root-zone Stress Temperatures.

by S. E. Newman, and Fred T. Davies, Jr.


Abstract:
The design for a chamber to control high root-zone temperature is presented. Air within the insulated chamber was heated with vinyl-jacketed heating cables and cooled with 1:1 water an antifreeze (v/v) pumped through copper coils. Control of the soil temperature was based upon air temperature around the soil containers within the sealed chambers. Chamber operating temperatures could be held between 20 degrees and 50 degrees C +/- 0.2 degrees SE.
