This list has been pretty quiet. Thats ok, doesn't fill up our email
boxes if nobody has anything to say. However feel free to bring up any
topics relating to any aspect of potatoes and modeling. Thats our
purpose.

Also a report on the Wageningen potato modeling workshop would be
nice -- Anton, Jan, John, Bert, Jukka, anyone? :-)

I am helping the developers of the 2d-Soil model (Dennis Timlin,
Yacob Pachepsky) connect the plant growth portion of the SIMPOTATO
model to their model. Some questions are coming up regarding
nitrogen uptake and active/passive uptake. Are ammonium or urea
taken up directly (I assume ammonium only), and is that active or
passive uptake? Are they taken up from the soil solution or is
ammonium coming off of soil mineral or organic particles? How
important is active uptake of nitrate?

I am hoping someone here can direct me to information/research in the
area of CO2 accumulation and its effects on Potatoes in storage and/or
in transportation. I can't seem to find anything, Any assistance would be
greatly appreciated.
