Soil Health; A Living Perspective
Optimising Soil Management for Agricultural Productivity and Ecology (6 BASIS points; 1LP, 2E, 1GM, 2N)
with Joel Williams
Date to be confirmed
Venue to be confirmed
This event is a comprehensive full day presentation, suitable for both commercial farmers (including but not restricted to organic producers) and those concerned with home/community production.
Joel's cv is impressive and extensive (see his profile for greater detail), but in short, after focussing more strongly on soil chemistry and nutrient balancing in Australia he worked with Elaine Ingham at Laverstoke in the UK, inverting the emphasis and focussing more strongly on optimising the soil biology with a reduced weighting to mineral management. Now he tends to take a middle road but is happy to deliver with whichever emphasis the audience prefers. He is particularly interested in the links between nutrition and pest and disease pressure, and how nutrient corrections when supplemented with biological protection can be used to manage insect and disease problems. After some time back in Australia, he returned to England and intends to again, but is currently based in Canada for a couple of years. Participants attending both have commented that this workshop was a good foundation for the Stewarding Your Soil course, which provides more practical elements related to making good compost and using microscopes; we plan to deliver similar courses in Spring 2018.
Joel was recommended to us by one of our farmers in the south-west a few years ago and and has proved popular since, with AHDB and other organisations frequently commissioning him to do shorter presentations for their audiences.
Here are some of the things people said about the initial day we ran in February 2015 (and they only get better!):
"Superb course, would love to learn more"
"A well structured, interesting and inspiring day"
"It was a really interesting, informative and inspiring course... I'll definitely be putting some of what I have learned into practice both at home and at..."
"Really interesting and understandable talk on soil that actually helped me understand what to look for practically and get enthused about fungi!"
"A big subject nicely broken down into nicely digestible chunks"
"Very interesting/exciting - even for the amateur (I thought it may well go over my head, but I took in a lot)"
"Quality, trustworthy information delivered in a very understandable way. Clarified a lot of the mysteries of soil biology"
"Excellent overview of soil biology and how to achieve better microbial health. Relevant for all audiences interesting in farming."
"Absolutely fantastic day! Well worth the trip from Aberdeen" (and that was to South Devon...)
"Highly informative... Well structured... Applied knowledge..."
