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 ...)

Cool Planet: can biochar fertilize soil and help fight climate change?

Cool Planet: can biochar fertilize soil and help fight climate change? Although market information and long-term impacts remain unknown, a biofuel byproduct can store carbon and enhance soil quality – and its market is growing despite higher costs A green energy startup intends to produce bio-based fuels from woody plants, and use the burnt byproducts as the basis for its biochar products.
Kaesekamp is very pleased with a certain group of around 20,000 grapevines he has been nurturing. Their yield has been 5% better than what he’d expected. Their root mass is greater than his other vines as well – which means they’ll hold water better. In drought-hit California, that’s gold. Kaesekamp, whose Knights Grapevine Nursery supplies vines and rootstocks to the region’s wineries, believes these vines did especially well thanks to a soil treatment called CoolTerra – a product made from a carbon-rich substance called “biochar” that is supposed to improve soil fertility and increase water and nutrient retention. Cool Planet Energy Systems – the startup company that manufactures CoolTerra – formed to produce a biofuel replacement for gasoline. The master plan was and remains to use wood chips, corn stover and non-food crops as the feedstocks for this fuel. The firm always intended to have a side venture in selling the byproducts as biochar. But right now, the business is all about CoolTerra – which is bringing in modest sep/02/cool-planet-biochar-charcoal-biomass-energy-gasoline-soil-fertilization#comments amounts of revenue.
