Why a biochar project?

What is The Whitmuir Biochar Project?
An innovative pilot project contributing to research and debate:
- does biochar improve soil fertility and crop production? - does biochar have a role to play in mitigating change mitigation?

The Whitmuir Biochar Project is sponsored by the Scottish Government’s Climate Challenge Fund
At Whitmuir we take our community’s woody waste, convert it into biochar in purpose built kilns, then use it
as a soil amendment to enhance crop growth

Composting
• Can biochar be used as dry waste to improve the composting process?
• One bin is layered with woodchip, one bin will be layered with biochar and woodchip.

Community led biochar growing trial
• 2 x polytunnels, 60 beds• 2 beds each: 1 control, 1 biochar
• 1kg of biochar per m²

How do we monitor results?
•Crops weighed & recorded by growers
•Crop results collated by volunteers & analysed
•External plots: Royal Botanical Gardens Edinburgh, Royal Caledonian Horticultural Society Organic Allotment

Unexpected Outcomes: School Involvement
“This project is fantastic. It
covers maths, science,
observation, growing, writing
and analysis skills. It is great preparation for the type of work the children will
do in High School.”
