Biochar Used on Rooftop Gardens and More

Hello biochar fans! Hope you all are doing well. Here is this week’s biochar roundup.

Australian ABC affiliate 612 ABC in Brisbane ran a feature last week about biochar. The audio interview centers on the two day workshop that took place in Meleny where biochar was discussed in depth. The interview touches on the basics of biochar including how it works and its benefits. Interestigly, biochar is compared to regular charcoal that goes into the ground instead of into a BBQ. Give this one a listen.

Next up, the blog good.is featured a great article on biochar. Here’s an exerpt:

Biochar doesn’t feed plants directly, but it makes soil a friendly environment for biological life. It helps soil retain water and communities of microbes that benefit plants. It keeps nitrogen—necessary for plant growth—from leaching into ground water. Overall, it’s been shown to raise crop yields. This isn’t a secret: Amazonian farmers used this techniques thousands of years ago to prepare thin soils for planting.

The article discusses how increasingly popular biochar is becoming “from Kansas to Kenya”. You can view it here.

Social Activists are looking to turn waste into biochar in underdeveloped countries like Haiti. They have started a changemakers project (think Kickstarter with a humanitarian twist) to help them accomplish this goal. The idea is to assist with sanitation in areas that need help and thereby transform the waste into usable biochar. It’s win-win! You can follow their progress here.

Here is a great presentation about using biochar on rooftop gardens. The piece is called “Urban Gardens” and offers several in-depth rooftop gardening tips. The presentation discusses the benefits of rooftop gardening, including the tips on how to lay out your rooftop garden for best results. Also included is a handy guide on how to use biochar in almost any small garden. You can view the presentation here.

Finally this week, here is yet another group of biochar lovers who decided to put biochar to the test in their fields. Here’s an excerpt from their experiment:

“Our (very) preliminary results indicate a significant improvement in yield, root production and leaf colour for radishes, garlic, onions, lettuces and pack choi (see photos below). We do not yet have a big enough dataset to give you conclusive results, but keep watching this space for new results.”

Follow their progress here.
