Restoring Heavy Metal Contaminated Soils Using Compost

Restoring Heavy Metal Contaminated Soils Using Compost feat

Metals become contaminants when their amounts in soil, reach levels that are toxic to human life, plants or other biological organisms. This creates a need for soil remediation. Remediation is the process of reducing the toxicity of contaminants or ridding the soil completely of toxic contaminants. Heavy metals (for example, arsenic, cadmium, lead and zinc) fall under the group of inorganic chemical contaminants (5). These metals are released into the […]

Biochar, A Brief History

Charcoal picture

Biochar, while boasting an ancient history, is actually just gaining popularity among many circles today. While it’s believed that ancient South American cultures would use biochar (or burning agricultural waste, covered in soil) to increase soil productivity, the term wasn’t coined until Peter Read did so in 2005, to describe a substance that looks almost like charcoal, but that is actually biomass carbonized and made into a solid material, used […]

Phytoremediation

Carafe of clean and dirty water

Phytoremediation is a biological technique used to restore polluted water and soil environments to their natural state. It involves the use of living plants and their related micro organisms to remove contaminants from the environment or to degrade contaminants to a lesser toxic form (1,2,6). Anthropogenic activities such as mine tailings, fertilizer applications, pesticides, heavy metal disposal, petrochemicals, animal manures and sewage sludges cause soil pollution (2,4,5). Heavy metals are […]

How Do You Restore Degraded Soil?

Sprout growing out of concrete

A degraded soil typically loses its ability to supply food and habitation to living organisms, in its surrounding. When this happens, effort is made to restore the soil back to its natural state. Characteristics of a degraded soil include: high salinity, decline in fertility, decline in organic matter (leading to decline in soil structure), soil erodibility, increase in alkalinity and acidity. Soil degradation can be caused by man: for example, […]

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 […]

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 […]

This Zero-Cost, Waste-Eliminating Practice Can Produce Abundant Crops from Healthy, Restored Soils for Generations to Come

Photography by Jasmine A Koster What is zero-cost, waste-eliminating and can restore soils to fertility to produce abundant crops for generations to come? Biochar. Gloria Flora gave a presentation on biochar at the Fourth Annual Inland Northwest Permaculture Convergence. She discussed biochar as a method for producing energy and amending soil from waste products that end up in the landfill. “This is the Permaculture idea of capturing everything…with the pig, […]
