breaks if not handled carefully. Individual sand grains can be readily seen and felt....Sandy Loam

B. Soil, squeezed in hand when dry, forms cast that bears careful handling; squeezed when moist,
forms a cast that can be handled quite freely without breaking. Soil smooth. Sand grains not readily
evident.
   C. Soil slightly plastic when moist, but not greasy. Gritty when dry, not floury
   Color brown or dark gray..............Loam.
