I love Richard's question and I hope to hear some useful suggestions.
Meanwhile, I would like to direct your attention to a 1998 paper, about using capacitance testers to estimate fresh root mass:
Agron J. 90:566-570. 1998
Does anyone has follow these and/or other experiences?
Best regards,
Jon

Dear DSSAT community,
Does anyone have an efficient/accurate method of measuring actual root length density and root weight for model development and testing purposes? Thank you for any help you can lend.
Sincerely,
Richard Ogoshi
