If the major soil constituents are fines, perform the following tests: Dry strength test: Mold a sample into 1/8″ size ball and let it dry. or "fishtail", drill bits are commonly used in stiff clay formations (Figure 3-1b). To measure soil moisture generally, look at it and feel it. Moisten a spot on the soil lump and rub a finger across it; if it is smooth it is clay, if marginally streaked-it is clay with silt, and if rough- it is silt SMD 1.1- 0.4 Moist. It consists of weathered rock, organic matter, air spaces and water. Soil texture can be estimated by hand, using the ribboning technique, but it takes practice to produce a consistent result. Double-Ring Infiltrometer is particularly effective in-field measurements of fine-grained soils, and gauges infiltration rate of … very light soil/water staining on fingers.

SMD O.9-0.3 Moist, forms a ball, very light water staining on fingers, darkened color, pliable, forms a weak ribbon between thumb and forefinger. Many soil conditions and components mentions earlier cause inconsistencies between field texture estimates and standard laboratory data. Since finger bits commonly leave a much larger amount of loose soil… One way to identify soil texture is to take a pinch of soil and wet it gradually, whilst kneading it between your fingers and thumb, until there is enough moisture to hold the soil together and the soil … Describe the strength as none, low, medium, high or very high depending on the results of the test as shown in Table 3(a). ATT-29 3.1.2 Amount of Water to Wet c) highdry strength - the dried sample cannot be powdered with finger pressure. The pressure which the expansive soil exerts , if it is not allowed to swell or the volume change of the soil is arrested , is known as Swell ing Pressure of Soil. It stains fingers.
