Soil is the complex body on the surface of a lithosphere subject to soil formation processes, comprised by mineral and organic matter, as well as living organisms.
Overview
Soil, comprising the pedosphere, is earthy material that has been affected by pedogenesis. The pedosphere is positioned at the interface of the lithosphere with the biosphere, atmosphere, and hydrosphere.
Soil forms through a variety of soil formation processes, and includes weathered rock "parent material" combined with dead and living organic matter and air. Soils are vital to all life on Earth because they support the growth of plants, which supply food and oxygen and absorb carbon dioxide and nitrogen.

@Thelurch I've heard of using Epsom salt but why should your plants be magnesium deficient? Are you using really old poor quality soil?
