Appearance of Sandy Clay Loam, Loam, and Silt Loam Soils
Appearance of sandy clay loam, loam, and silt loam soils at various soil moisture conditions.
Available Water Capacity 1.5-2.1 inches/foot:
Percent Available: Currently available soil moisture as a percent of available water capacity.
In/ft. Depleted: Inches of water needed to refill a foot of soil to field capacity.
0-25 percent available 2.1-1.1 in./ft. depleted: Dry, soil aggregations break away easily, no staining on fingers, clods crumble with applied pressure. (Not pictured)
25-50 percent available 1.6-0.8 in./ft. depleted (Figure 1): Slightly moist, forms a weak ball with rough surfaces, no water staining on fingers, few aggregated soil grains break away.
50-75 percent available 1.1-0.4 in./ft. depleted (Figure 2): Moist, forms a ball, very light staining on fingers, darkened color, pliable, forms a weak ribbon between the thumb and forefinger.
75-100 percent available 0.5-0.0 in/ft. depleted (Figure 3): 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 in/ft. 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 pictured)
