i. Mollisols get their name from a Latin word meaning soft.
ii. The surface layer of a moliisol is soft, dark, fertile, and deep.
iii. The typical moliisol is formed under closely spaced grasses.
iv. If the climate is too dry for a dense stand of grass, the soil is likely to be an aridisol – too hard, light, or salty to be a moliisol.
v. Rainier climates usually support trees whose leaves form a mat on the surface rather than a thick mixture of organic material and mineral soil.
vi. Earthworms are an important aspect in softening and mixing a mollisol; they add one more reason that the order of mollisols includes some of the most productive soils in the world.
