What is relation between osmotic suction in a soil and chemical properties of the soil?

10 October 2013 1 3K Report

For example Fredlund and Rahardjo (1993) presented this relation: π=31.92*EC^1.08. is there any other relation?

The short answer is: π = -RTcs.

The long answer can be found in one of the boxes in chapter 3 in Lambers, H., Chapin, F.S. III & Pons, T.L. 2008. Plant Physiological Ecology. 2nd edition. Springer, New York.

I attach a PDF of those boxes for your perusal.

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...
