Russ,
A great reply, and very informative to our members. Did this come off your head, or did you look up. Doesn't matter, a great reply!!

Calcium cyanamide, educate me!

I assume you mean below 50 degrees soil temperature the microorganism become inactive, and any win in uf is basically unavailable.

HWIN fraction in uf usually breaks down in 1 yr, but a very small amount can take years!
