Soil Formation

Colourful

Soil is formed through the process of rock weathering. Weathering is the breakdown of rocks into smaller particles when in contact with water (flowing through rocks), air or living organisms. Weathering can occur physically, biologically or chemically. Physical weathering: This is the disintegration of rocks into smaller particles with no alteration in their molecular structure. Air and water are agents of physical weathering. Windblown on rocks, heavy downpour of rain, […]

A Guide to Simple Worm Farming Techniques

Happy Tiger Worms (Courtesy of Timothy Musson)

Even novice gardeners are aware of worms as a driving force in the garden, and this is especially so for those no-till beds so popular in permaculture plots.

Food Sovereignty

pt01

‘Food sovereignty’ is fast becoming a lost concept; the right to have the knowledge and resources to grow our own food is an essential right. If we don’t have access to nutrient dense organic food, then where do we get the essential energy to heal our body, mind and spirit certainly not from the supermarket where the average ‘fresh food’, in Australia food often travels more than 1000klms from farm […]

Soil Degradation: Another Carbon Story

Soil degradation can be a depressing topic. It is generally accepted that the decline in soil quality across Australia following European settlement has been extensive, and extreme in some areas. Soil degradation involves a reduction in soil quality, and this can refer to a decline in physical, chemical or biological properties, or to the actual loss of soil through erosion and transport away from the land. And these are commonly […]
