About

The person behind
the humus.

Master gardener, entrepreneur, carbon-farming pioneer – and above all someone who loves the soil. This is my story: from bagging peat on my parents‘ farm to a mission to bring soils back to life worldwide.

My path

Every step was a school of the soil

Four decades, three continents, one common thread: how dead earth becomes living soil.

The Roots

Raised in the family horticulture business in Cloppenburg – among bags of peat, soil and an early love for the land.

The World

Tea plantations in the Himalayas, fields in Spain and South Africa, a tropical house in Switzerland.

The Science

Biogas plants, mycorrhiza labs, smart carbon farming – where experience became measurable knowledge.

The Mission

Today I build soil-regeneration projects for farmers, investors and municipalities with Humus Guru GmbH and tgo AG.

The Good Ones Farm

„Here I live what I teach.“

Together with my wife Claudia, we are building a living proof on 1.6 hectares: regenerative agriculture that works. We produce our own humus, generate energy autonomously from the sun, run water in a closed loop and let robots help with weeding – a model and learning site for the farming of tomorrow.
