Soil -- any soil -- is made up of tiny granules of rock plus minerals, gases and liquids. The constitution of any soil depends on where the soil exists, because that soil has been effected by that locale's weather, erosion, and natural environment.

The notion of organic soil means soil that has not been mixed with commercial herbicides, pesticides or other man-made chemicals.


Depending on the chemicals added, it may take a few years or a few decades or more for the soil to naturally break down the chemicals and be usable as 'organic soil' with no traces of chemical additives.

Amending, composting, fertilizing, green-manuring, and mulching are ways to make soil organic. An organic soil is rich in macro- and micro-nutrients which control waterlogging, create air and water pore spaces, encourage infiltration and percolation, facilitate drainage, and support such soil food web members as beneficial invertebrates and plant roots. Compost from naturally decomposed carbon- and nitrogen-rich organic materials and humus from naturally water- and wind-eroded geological formations serve to differentiate nutrient-poor dirt from nutrient-rich soil.
