Title:	Effect of heat on soil color and pH of two forest soils.
Author(s):	Tarrant, Robert F.
Date:	1953
Source:	PNW Old Series Research Notes No. 90: 5 p.
Station ID:	OSN-PNW-090
Description:	Intensity of a slash burn is often judged by the change in soil color. Reddened or yellowed areas of soil and charred patches of organic litter are found on most burned areas, but such color changes are difficult to interpret. A study was therefore made to explore two questions: (1) At what temperature does the color of mineral soil change to the reddish or yellowish hues found on severely burned spots? (2) How do high temperatures of varying duration affect soil reaction (pH)?
