Soil Ingredients

Air, water, minerals, and organic matter (living and non-living) are the basic ingredients of soils. They occur in many combinations. The relative proportions of these ingredients affect how a soil behaves, what kinds of plants grow in it, and how well they grow.

What’s not solid is just as important. Roots and organisms need the water and air that fill the spaces between soil particles.
