| + | Soil texture refers to the relative proportions of sand, silt, and clay particles which | ||
| + | make up the soil mass. Figure 6 shows the percentages these soil fractions in the basic | ||
| + | textural grades; definitions and discussion of this subject may be found in the | ||
| + | Soil Survey Manual (Agriculture Handbook 18, U.S. Department of Agriculture, 503 pp., 1951). | ||
| + | |||
| + | Soil texture can be found exactly in a laboratory analysis. It can also be adequately | ||
| + | classified in the field, after some experience, by sight and feel. On the opposite page | ||
| + | is a key to the important textural grades. The first three -- sandy loam, loam, and silt | ||
| + | loam-- are common surface soils, and may occur as subsoils. The rest are subsoils. | ||
