episode 10: #10 Fertile woodchips and managing the tree line understory with Iain Tolhurst
In this episode, Iain Tolhurst explains why and how he integrated trees in his vegetable operation. It's interesting to get a clear image of what his tree layout looks like, and what this means in term on infrastructure and management. He has tested planting perennial crops in the tree understory, a tempting idea that encounters some practical and commercial limitations. We cover some issues such as if we should be worried of weeds growing in the tree line or if root and light competition are a challenge for him. We then explore another interesting aspect of his farm : how he uses woodchips to fulfil 100% of his fertility needs and how much of his land he would need to dedicate to tree cover if he were to produce all his inputs onsite. As a little bonus, we indulge in a little off topic but fascinating conversation on organic matter.
