soil stats
(OP)
Does anyone know the temperature and relative humidity of soil, with respect to depth and season? Are there any databases on the internet where I can find such stats?

RE: soil stats
I'll respectfully disagree. Rh (relative humidity) is different from S (degree of saturation.) They have different definitions and means for measurement.
Two soil samples with identical dry weights can be in identical jars with identical amounts of water in each jar. Both jars have identical values of S.
Assume that both jars are also at the same temperature. The Rh in one jar is lower than the other. Why? The jar with the lower Rh has salt in it. The difference between the Rh values has everything to do with the type and quantity of salt present.
Pore water chemistry is a crucial factor in evaluating Rh, and it is similar to - but different from - degree of saturation -
It's a fun (and challenging) topic...
