Biochar
- 1. Introducing Biochar The facts and information!
- 2. What is biochar? Organic materials are heated in a process called pyrolysis to produce charcoal Charcoal is then stored in the ground to reduce carbon dioxide, aid in food security, condition soil and improve productivity
- 3. So what does this mean? • Improved soil pH and increase amount of water to be held • Improved nitrogen use efficiency and crop productivity • Potentially eliminate the amount of carbon dioxide in the atmosphere • Potentially decrease methane and nitrous oxide from soil
- 4. How to apply? • At current not much set information regarding application • Some options are; deep banding, and application through liquid slurries • MORE RESEARCH IS NECESSARY FOR BEST METHODS OF APPLYING
- 5. Implications? • Biochar does not work with all soils. Biochar can actually repress plant/crop growth in unsuitable soils • Concern over the efficacy and bioavailability of agrochemicals when applied to biochar amended soils • Minimal land across the earth which can be used • Can reduce soil albedo
- 6. Conclusions • Much research is still needed to completely confirm the advantages and disadvantages of employing biochar. • Could be the answer to the Australian agriculture industry
Editor's Notes
- Good afternoon everyone! Today I will be presenting to you the current information and need to know facts of biochar. There is quite a dense amount of information, so I promise to keep the presentation nice and brief and a leaflet will be available after for you to take home with all the detailed facts and information.
- So what exactly is biochar? Biochar is the newest technologywhich can potentially provide various benefits for the agricultural industry and our planet. The employment of biochar can help reduce the ever increasing amounts of carbon dioxide in the atmosphere, can be used as a soil conditioner and can improve productivity and food security. Biochar in its simplest form is produced through organic materials such as crop stubble, woodchips, manure and municipal waste in a heating process called pyrolysis.
- By employing biochar into our soil we can expect (subject to research found) improved soil pH, increased amount of water that can be held in the soil, improved nitrogen use efficiency and crop productivity. Biochar also has the potential to help eliminate the amount of carbon dioxide in the air and potentially decrease methane and nitrous oxide from soil. This can thus potentially help climate change and be a tool to further increase the success and results of the agricultural industry. However research is still young and much more needs to be carried out before anything can be completely conclusive.
- In order to apply biochar more research needs to be conducted. So far research has pointed towards deep banding and applying biochar through liquid slurries.
- With everything there is usually some kind of implication. The implications of biochar are quite minimal when weighing up the advantages with the research to date. However they do lack in-depth research. (read slide)
- In conclusion although biochar seems like a great answer to aid with sustaining our environment, much research still needs to be conducted on all the pro’s and con’s. Ideally biochar will be a new technology that will bring many benefits to the Australian agricultural industry. Thank you for listening. Please take one of these leaflets each for a much more in-depth review. I will be here for another half an hour if anyone has any questions regarding this information.
