The Woodland Trust has partnered with UK biochar supplier Carbon Gold to support the charity’s tree planting and preservation activities across the UK.

The announcement will see 10p from the sale of each of Carbon Gold’s biochar planting aids and soil improvers donated to the Trust.

Philippa Borrill, head of partnerships at the Woodland Trust said: “Carbon Gold is a natural fit for us as a partner. Their biochar products are proven to boost the health and vitality of newly planted and established trees and plants.

“We’re looking forward to seeing what this collaboration brings in terms of supporting our estate and in raising awareness of biochar and its benefit in boosting tree health.”

Biochar is a high-carbon, purified form of charcoal that improves the structure, aeration, water-holding capacity and nutrient retention of all soil types. Importantly it provides a permanent refuge for beneficial soil microbiology, supporting tree health.

Carbon Gold’s biochar products are enriched with fungi, nutrients and trace minerals. Trees treated with it in trials have been shown to have increased tolerance to pests and diseases including honey fungus and ash dieback, and environmental pressures such as drought and transplant shock.

Executive chairman and founder of Carbon Gold, Craig Sams said: “Expanding the UK’s woodland is one of our primary goals as a business, which makes the Woodland Trust the perfect organisation to partner with to raise awareness of biochar and its impact on tree health among the general public.”
