Sandy Clay, Loam, and Silt Loam Soils
Appearance of sandy clay, loam, and silt loam soils at various soil moisture
Available Water Capacity = 1.5 to 2.1 inches per foot
Percent Available: Currently available soil moisture as a
percent of available water capacity.
Inches per Foot Depleted: Inches of water currently needed to
refill a foot of soil to field capacity.
0 to 25 percent available 2.1 to 1.1 inches per foot depleted
Dry, soil aggregations break away easily, no staining on fingers, clods
crumble with applied pressure. (Not pictured)
25 to 50 percent available 1.6 to 0.8 inches per foot depleted
Slightly moist, forms a weak ball with rough surfaces, no water staining on
fingers, few aggregated soil grains break away.
50 to 75 percent available 1.1 to 0.4 inches per foot depleted
Moist, forms a ball, very light staining on fingers, darkened color, pliable,
forms a weak ribbon between the thumb and forefinger.
75 to 100 percent available 0.5 to 0.0 inches per foot depleted
Wet, forms a ball with well-defined finger marks, light to heavy soil/water
coating on fingers, ribbons between thumb and forefinger.
100 percent available 0.0 inches per foot depleted (field capacity)
Wet, forms a soft ball, free water appears briefly on soil surface after
squeezing or shaking, medium to heavy soil/water coating on fingers. (Not
