When soil moisture exceeds 20 %, there's a high mortality in flea larvae.
The daily electrical - capacitance variations decreased
when soil moisture was below the wilting point and completely ceased below the soil volumetric water content of 11 percent, suggesting that the effect of water stress on electrical capacitance was observed through its impact on photosynthesis.

when the plant is unable to take up adequate calcium, a condition caused by fluctuating
soil moisture (drought or overwatering), high nitrogen fertilization, or root pruning during cultivation.

when you combine the precipitation data with temperature information to get an idea of how much
moisture is being evaporated from the
soil.
I guess you could view the nodes and links that I was describing as a layer of network above those you see on Tsonis's site if each of his spatial graphs (networks) were for one parameter such as wind velocity, humidity, pressure, temperature, evaporation rate,
soil moisture, etc and extended to three dimensions
when proper.
Depending on the region, the persistence from spring to summer of
soil moisture or snow anomalies generated during spring by temperature and precipitation variations may explain river flows variations in summer,
when no concomitant climate variations exist.
When the
soil is wet, part of the sun's energy is diverted from warming the
soil to vaporizing its
moisture, creating a cooling effect.

Relative humidity of surface air is not shown, but referred to
when it provides complementary information to the precipitation and
soil moisture analysis.
Direct observations of
soil moisture are not assimilated; analyses are constrained instead by the mismatches between synoptic temperature and humidity observations and corresponding background forecasts, in snow - free regions
when meteorological conditions are appropriate.
The radar images provided a comprehensive picture of
soil density,
moisture and local structures which,
when combined with the photographs taken from the aircraft, enabled the researchers to find and examine the city's characteristic temples and artificial ponds used for irrigation and water storage.
The DTR reduction by clouds is largest in warm and dry seasons such as autumn over northern midlatitudes
