The relative percentages of sand, silt, and clay are what give soil its texture. In general, the smaller the soil particle size distribution, the slower it will drain. A Holdrege silt loam, for example, describes the texture of the surface horizon. texture of soil samples have been estimated in samples, Q1 and Q2, as clay loam, in samples S1, S2 and S3 as sand y loam, in samples S4,S5 and S6 as loam, in samples S7, S9 and S9 as clay loam Loam soil consists of three textural components that are silt, sand, and clay. These elements are mixed with organic matter, water and air to create loam soils. The point where they converge is the soil texture; in this case, between a sandy loam and a sandy clay loam. Such soils are often referred to as medium textured soils (Figure 2). Soil texture is a major determinant of the workability, water retention, and drainage of soils, along with the level of organic matter (see the POXC and particulate organic matter tests) and level of aggregation (see the aggregate stability test). Particle-size distribution after dissolution of organic cements confirmed the field observations, giving a silty loam texture for the E, EB, Bw and 4BC horizons and a silty clay to silty clay loam texture for the other horizons (Table 7). "Loam means you have roughly equal portions of sand, silt and clay," he said. Soil texture describes the proportion of three sizes of soil particles and the fineness or coarseness of a soil.
