What soil is should at first sight be pretty self evident but to a soil scientist, yes there is such a person (they study soil), soil is a very complex thing. The problem is we all tend to overlook soil; it’s that muddy stuff in the garden. It is though a complex and delicate ecosystem in its own right. The main parts are:

• Soil water
• Organic mater
• Soil flora
• Soil fauna
• Mineral components
• Soil air
