Soil types and texture

Soil Fertility Soil Structure Life Beneath

Soils in any location are the unique result of the specific local interactions of climate, geology, hydrology and management.  Soils form as a result of the physical and chemical alteration (weathering) of parent materials (solid rocks and drift deposits).  Biological activity is a critical component of soil formation; soil is distinguished from weathered rocks as a result of the biological cycles of growth and decay leading to the incorporation of organic matter.  

Soil parent material controls a range of soil properties including soil depth, stoniness, mineralogy and texture. 

The amount of sand, silt and clay in the soil defines the soil texture. The texture cannot be easily changed, but it is important that you know the texture of your soil (and whether it changes with depth). Texture plays a large part in determining the how easy the soil is to work during cultivation and is often used to indicate how resilient the soil is to structural damage.
