Compost Tea & Leaf Sap Analysis, explained by a Regenerative Farmer [Adrian Rubi]

What happens when a farmer becomes a microbiologist? Adrian Rubi shares how compost tea, leaf sap analysis, and on-farm ferments can help you cut inputs, strengthen crops, and speed up your regenerative agriculture transition. From recipe design and dissolved oxygen to trace-element tweaks and manure management, this is soil microbiology you can actually use. Why listen: Reduce fertilizer costs, improve plant health, and scale nature-based solutions with tools you can brew and measure on-farm. Inside This Episode:🌾 Transitioning the Swiss hillside farm: organic suckler cows, hazelnuts, and local feeds only. 🧪 Compost tea ≠ fertilizer: secondary metabolites, foliar benefits, and practical application rates. ⚙️ Brewer design that keeps biology aerobic and consistent (stainless steel, vortex flow, DO control). 🌿 Leaf sap analysis to target trace elements, avoid over-fertilizing, and keep photosynthesis high. 🧴 Ferments for manure pits and cover-crop mulch: fewer smells, healthier N cycling.—Produced in partnership with Soil Capital, a company accelerating the regenerative transition by financially rewarding farmers who improve soil health & biodiversity.https://www.soilcapital.com/—Usefull Links:EDAPRO: https://edapro.ch/en/ALTERHUS FARM: https://www.instagram.com/halterhus/Hosted on Ausha.
