Soil Recipes

Different soil “recipes” yield different soils, depending on various “ingredients,” soil-forming factors, and time.

Soils begin to form when sediment, organic matter, or rock—parent material—is first deposited or exposed, often by water, wind, or ice.

Soils develop as parent material ages in place, changed by climate, soil organisms, and the terrain.

Soils take shape in surprising ways—as water moves minerals and elements from one layer to another, as living organisms take out nutrients and add organic matter, or as new minerals form.

Soils are constantly changing.
