What a coup! ‘Vulgariser of science’ (a brilliant French phrase) and inspirational mycologist Marc-André Selosse, makes his first appearance at Groundswell. An unmissably energetic speaker, Marc-André will bring home the urgency of improving soil health, explain what makes for healthy soil and why earthworms have an important role to play. This theory will be brought to life by Jules Phillips’ 7 year journey of increasing worm populations at Ham Street vineyard, plus Joel from Vinescapes’ experiences of improving UK vineyard soils through building soil biology. Joel will also bring along his worm demo farm. Come see the galleries yourselves!
