Soil Chemistry

This term indicates the relative content of particles of various sizes, such as sand, silt and clay in the soil.

• texture

• type

• pH

• nutrient content

When soils are waterlogged it is likely that this nutrient will be lost through leaching, resulting eventually in the older leaves of the plant yellowing.

• N₂O - Nitrous Oxide

• Nitrogen

• Oxygen

• Atomospheric gases (Air)

This refers to a type of water that can escape from the soil.

• capillary

• hygroscopic

• flowing

• gravitational
