- air:Soil Air refers to the soil atmosphere, the gaseous phase of the soil that is neither solid nor liquid.
WaterSoil Water or Soil Solution is the liquid phase of the soil containing dissolved salts and chemicals (ions) that are free-floating and not attached to any solid particles (mineral surfaces).
Mineral Particles: The Mineral Side of SoilThe mineral part of soil is composed of varying amounts of
sand,
silt, and
clay. With a few exceptions that we will cover, these particles are not derived from materials that were once living, meaning that minerals are inorganic. Their characteristics greatly influence soil behavior and management needs.
