Definition Climate Farming

Climate farming uses agricultural means to keep carbon dioxide and other greenhouse gasses from escaping into the atmosphere. Like organic farming, climate farming maintains biodiversity and ecological balance on productive, argicultural land. But climate farmers like Hans-Peter Schmidt go a step further and covert leftover organic mass into biochar, a solid carbon compound that can improve soil quality. Biochar production also creates a kind of gas that can then be burned to help generate power. A climate farm could grow food, generate power, and help keep carbon out of the air.

Climatefarming – Pour une agriculture durable

von Hans-Peter Schmidt

Le climatefarming est souvent décrit comme une méthode agricole au moyen de laquelle du CO2 est prélevé de l’atmosphère et stocké de façon stable dans le sol sous forme de carbone. Ceci pourrait permettre de freiner le changement climatique. Mais le climatefarming, c’est également un concept écologique durable pour l’agriculture du future, qui produira aussi bien des denrées alimentaires que de l’énergie et de l’air propre, encouragera la biodiversité et protégera le paysage.

Au travers de leurs feuilles, les plantes prélèvent du dioxyde de carbone contenu dans l’air et le transforment à l’aide de la lumière, de substances minérales et de l’eau en molécules carboniques. Lorsque la plante meurt ou pourrit, ou si elle est mangée et digérée, les molécules longues de carbone sont de nouveau scindées. Ce processus libère de l’énergie et donc du carbone qui, composé à plus de 99% de CO2, s’évapore dans l’atmosphère. (en savoir plus ...)

Biochar investigated for increasing soil biota

UWA PhD student is evaluating how biochar—a stable form of charcoal commonly used in carbon sequestration and as a soil conditioner—influences soil micro-organisms.

“Improvement in the biological status of soil is important because it helps regulate nutrient cycling and improves conditions for root growth.”— Noraini MD Jaafar. Image: flickr (Truthout.org)

School of Earth and Environment Researcher Noraini MD Jaafar says the study aims to determine the role of biochar in soil as a habitat for soil organisms and the effect of biochar on growth and functioning of arbuscular mycorrhizal fungi and other microbial activities.

“Biochar may improve the ability of beneficial microorganisms to increase the efficiency of plant nutrient acquisition. Combinations of biochar and mycorrhizal fungi may improve microbial activity and nutrient status of soil,” she says. ....
