Chemical Health

Soils are complex systems with physical, chemical, and biological characteristics that vary over time and space. Major components, including silicon, aluminium, and iron, along with oxygen, are responsible for much of the soil matrix. Other major components include, but are not limited to, manganese, magnesium, potassium, calcium, and titanium.

A large number of other elements are often described as trace elements when considered beneficial and heavy metals when present in excessive amounts or known to be intrinsically hostile to living organisms at any level.

The more significant ones are cadmium, copper, mercury, nickel, lead, and zinc.
