Carbon gold studies show enriched biochar suppresses ash dieback

Tree care products produced by Carbon Gold have been found to suppress ash dieback in a recent study featured on the BBC’s Countryfile.

The research featured on the BBC’s best-loved programme reveals that ash dieback could be more effectively managed and the spread of the disease slowed and potentially halted using Carbon Gold’s biochar-based Tree Soil Improver.

The study was carried out by Bartlett Tree Research Laboratory, the leading organisation on tree science in the UK and the US and a Carbon Gold customer. It took place on a site in Essex managed by the Woodland Trust and known to be infected with ash dieback. The programme monitored 2,000 established ash trees over a three year period, during which one third had become infected. Ash trees treated with Carbon Gold’s enriched biochar however were proven to be more resistant to the disease and none were infected. When these results were released, Countryfile was keen to investigate.


Simon Manley, CEO for Carbon Gold says, “We are thrilled with the results this sStudy has produced so far. We continue to work with Bartlett Tree Research Laboratory as part of this ongoing research on the effects of our tree products into a range of different tree health issues over the coming years.

“The results of this study are a positive endorsement of the Carbon Gold product range and show how they deliver vitality and vigour to trees, plants and shrubs grown in soils or growing mediums where enriched biochar is present. These are same benefits that our retail customers have been enjoying since the products came onto the market several years ago.

“Consumers spend a vast amount on plants without a thought for the soils into which they are planted. Our Soil Improver is an easy way to link plant and tree sales to higher survival rates, quicker establishment and increased root vigour.”
