osmotic coefficients

I wand to model root water uptake with additive solute stress.

How does hydrus calculate the osmotic pressure? my solute units are in mg but hydrus is indifferent to solute units. Is that incorporated in the osmotic coefficients? how are they determined?

You need to enter by yourself the osmotic coefficients that will do the unit conversion from the concentration unitz to units used by the stress response function J.

OK, Thanks!
