Dear All,

I recently wrote an article on root development in wheat (I can provide an
electronic cope to those of you interested). Hope it can help. Any comment /
suggestion is very much welcome.

In-season wheat root growth and soil water extraction in the Mediterranean
environment of northern Syria Agricultural Water Management, Volume 95, Issue
3, March 2008, Pages 259-270 G. Izzi, H.J. Farahani, A. Bruggeman, T.Y. Oweis

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
