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, […]

Learning More on How to Think about Soil

Seedling & Soil

I don’t know why it is, but I’ve taken to waking up at about five every morning. I kiss my wife Emma on the head, creep downstairs from the loft of our apartment and spend the next hour or more watching Geoff Lawton videos from the PDC course. She knows I’m doing it. It’s nothing weird. But, for the most part, we don’t talk all that much about it. This […]

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. For most of us, it’s no great revelation that soil thick with worms is also likely to be thick with plant growth. The reasons are many, but in the most basic terms, earthworms are great for aerating soils and transforming organic material […]

A Peep Into the Underground Biological Market

Ravindra Krishnamurthy feat

Symbiotic relationship between plants and mychorrhizal fungi has been in existence for over 400 million years. Fungi cannot survive on their own as they are incapable of producing their own food. Hence, they latch on to the plants roots to get essential food. Plants share a part of the carbohydrates produced during photosynthesis and in return, fungi supply phosphates and other minerals, by mining them from the soil. These natural […]

Save our Soils

Save our Soils

All terrestrial life depends on soil, directly or indirectly. Although our understanding of topsoil has grown by leaps and bounds over the past decades, we are still losing this invaluable resource at a frightening pace. Less than thirty per cent of the world’s topsoil remains in fair or acceptable condition. The fragility of this vital layer can be illustrated through a simple comparison: if one imagines the earth as an […]

HOW SOIL AND CARBON ARE RELATED

IMG_8028Ingrid Pullen Photography

Carbon cycle is one of the fundamental requirement of life on earth. Soil organic carbon (SOC) can be described as the amount of carbon that is stored in the soil as one of the components of organic matter which comprises the animal and plant materials and different stages of decay. Organic carbon (OC) mainly enters the soil by the decomposition of the animal and plant residuals, dead and living microorganisms, […]

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 […]

Home Garden Soil Health Assessment

Download the complete Home Garden Soil Health Assessment document here Growing food in a home garden is sensational. The most obvious sensation is the taste. If you don’t know how much better home grown fruit and veggies can taste, then ask an old person what tomatoes used to taste like. But the sight of a productive garden can be inspiring as well. It takes a shift from the modern urban […]

Contour Beds Peru

The ancient Inca also utilised contour patterning in their agriculture. This article will describe the process we took to create kitchen garden contour beds in the Sacred Valley Peru. Contour beds are annual and/or perennial vegetable garden beds that conform to the natural pattern of the landscape. Being on contour means that the paths and beds themselves are level and follow the lay of the land. Not only does this […]

Nursery Quality to Tree Planting Success – the “Airpot”

We can be proud of many landscape tree outcomes, but there are some alarming tree failures in our parks and streets that are costing us millions. Up to six parties are responsible for landscape tree outcomes: the designer, propagator, grower, planter, waterer and maintenance crew. Too often the grower alone is held to account for any problems.
