The land judging cards we will be discussing are single field cards. But for state and national contest you will be using a four field carbon self-grading card. Texture Soil texture refers to the relative proportion of sand, silt, and clay particles in a specific soil mass. It is easiest to determine when the soil is moist. Sand feels gritty when rubbed by the finger.
Silt feels slick or velvety.
Clay is usually sticky and plastic when wet and when pinched between the thumb and finger forms a flexible ribbon. The surface texture is normally determined from at least plow depth or 6 inches, however, erosion may have removed the surface to such an extent that only 1 or 2 inches may remain. For contests, a boxed sample of surface soil and subsoil will be provided to judge texture. In soils, several subdivisions of texture are recognized and are illustrated below. For land judging we recognize five texture categories represented by the middle column of the accompanying table.
