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.

FOLLOWING IS A TABLE ON CONVERTING CENTIBARS TO AVAILABLE WATER

20CB...........80 PERCENT PLANT AVAILABLE WATER  
30CB...........75 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
