Soil Fertility and Organic Matter

Soil quality is the capacity of a soil to accept, store and recycle water, minerals and energy for optimum growth and it's ability to preserve a healthy environment.

The capacity of each soil differs depending on the processes which formed the soil, the weathering etc it has been subjected to since and of course any agricultural practices etc that have taken place on it.  The texture, structure, chemical properties and organic matter content of a soil all of an affect on it's quality.

Getting to Know Your Soil: Colour

Every soil has it's own combinations of characteristics, that affect the nature of your soil and how it performs.  These characteristics can be broadly grouped into three, inter-connected, groupings:

• Physical
• Chemical
• Biological

Lets Get Physical!

The physical characteristics of your soil are the aspects that you can actually see and feel.  They include it's colour, texture, structure, strength, depth and stoniness.

In this post, we're going to look solely at the colour of your soil.

Soil Profiles

"dark, crumbly with a hint of stickiness,

3000 years young, 

seeks similar for fun and good times!"

Okay, so not perhaps the kind of profile you were expecting... :)

The soil profile is a 3-dimensional section of the soil.  In this, you can detect different layers (the 'horizons'), which are influenced by different factors in soil formation (see the 'Soil: What it is and where it came from' post) and also drainage and management practises.  A soil profile can vary from as little as a few centimetres, to many metres in depth.

The different horizons can be detected by being able to distinguish the separate colours, structure and textures from one to the next.  In theory...

Soil: What it is and where it came from

It has always amazed me how many of us are ignorant of the earth we stand on.

Even gardeners are often confused about where their soil came from, what type it is and how it can affect the plants that they grow.  Many will follow standard instructions on adding sand to clay to help it drain, and lime to sweeten it, without really understanding why they're doing it or the effect these actions may have.

So, to try and increase our knowledge a bit, this is going to be the first of a series of posts designed to give the average Joe (or Wayne if you're an Aussie!), a good working knowledge of soil.
