Soil is one of the earth’s most precious resources and is essentially non-renewable, due to its extremely slow formation processes. Formed from minerals, organic matter, water, air and a myriad of living organisms, it fulfils a range of essential biological and socio-economic roles. 2015 is the International Year of Soils.
