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. VALUES GREATER THAN  
50 INDICATE VERY MOIST SOIL CONDITIONS.  
 
SOIL MOISTURE /CENTIBARS/ AT LISTED DEPTH
