I am currently writing a review paper on the effects of freezing and freeze-thaw processes on soil phosphorus. The literature is relatively sparse (when compared to C and N) on this and I am keen to see if anybody has any grey literature or just papers in general that I might have not come across. If you are interested, please get in touch. I've been working on this for a while, and it has given me some interesting new research questions! Thanks in advance for any information/help.
