Trees, Roots, Fungi, Soil (Part 2)
Towards a model of good soil practice for arboriculture
30th June 2009
Linnean Society, Burlington House, Piccadilly, London W1J 0BF
There is much to be gained from an effective dialogue between ecology and arboriculture if we are to reach a meaningful understanding of health and pathogenicity in relation to soil and roots.

Understanding the soil rooting environment should be the first port of call for all practitioners involved in tree care. Arboriculture to date has been poorly served by ‘science’ with regard to the soil. While there is common use of expensive trunk decay investigation devices, there is no available conventional toolkit for looking at the soil as a matter of routine.
Without a clear understanding of functioning soil ecology, there is no ecological basis for restoration, where tree stress implies problems with the soil. One consequence of this is a focus on pests and diseases, inputs and outputs and agrichemical solutions. This seminar explored these themes and the prospects for a meaningful dialogue between adherents to the inputs-outputs and eco-system models.
