This research examines how button mushrooms use their growing medium (substrate) and how the fungal network feeds mushroom production. The study reveals that mushrooms use different layers of their substrate systematically over time and that there are limits to how far nutrients can travel through the fungal network. This knowledge is important for improving mushroom farming efficiency. Impacts on everyday life: – Helps mushroom farmers optimize their growing conditions for better yields – Could lead to more sustainable mushroom production methods – May result in more cost-effective mushroom cultivation – Could contribute to reducing waste in mushroom farming – May help develop more efficient growing systems for commercial mushroom production
