Re: Organic Matter X TDR calibration

[Kevin O'Connor]

Wenceslau,

You should look at:

Bohl, H. and K. Roth.  1994.   Evaluation of Dielectric Mixing Models to
Describe the Water Content vs Dielectric Number Relation.  Proceedings of
the Symposium on Time Domain Reflectometry in Environmental, Infrastructure,
and Mining Applications, Evanston, Illinois, Sept 7-9, U.S. Bureau of Mines,
Special Publication SP 19-94, NTIS PB95-105789, pp. 309-319

Let me know if you have trouble locating this paper.

Sincerely,
Kevin O'Connor
