Bücher von Gareth Davies

Gareth Davies, Phil Sumption and Anton Rosenfeld work as part of the Organic Research and Development programme of Garden Organic [formerly the Henry Doubleday Research Association], a charitable organisation dedicated to research into, and the promotion of, organic gardening, farming and food. Each of them has a strong record in practical organic farming research, especially in organic horticulture, and have played a prominent part in the development and sharing of knowledge about pest and disease management in organic farming systems.
