Field capacity of silt loam and clay loam soils is approximately
35 percent of volumetric soil moisture. The plant available water
of these soils is available to plants at values between 13 and 45
percent. To approximate plant available water as listed in the next
section...divide the listed value by 40 and multiply by 100. For
example...30/40 times 100 equals 75 percent. Resulting values of
greater than 50 indicate very moist soil conditions.

Soil Moisture (soil tension) /centibars/ at listed depth
Values are in centibars. 200 cB is dry...0 is wet.

Great Falls   3776              200        255   200    62
Following is a table on converting centibars to available water
in loam and clay/loam soils
 10cB or less...More than 95 percent plant available water
 20cB...........80 percent plant available water
 30cB...........75 percent plant available water
 40cB...........65 percent plant available water
 50cB...........55 percent plant available water
 60cB...........50 percent plant available water
 70cB...........45 percent plant available water
 80cB...........40 percent plant available water
 81-85cB........38 percent plant available water
 85cB or more...No available water


  0-10 centibars = saturated soil
 10-30 centibars = soil is adequately wet
 30-60 centibars = some watering necessary for most soils
 60-85 centibars = some watering necessary for heavy clay soils
 85+   centibars = soil is dry to very dry
