humus build-up.

Humus is not created by adding something, but by the interplay of soil structure, water, air and life. I show you what really works, which factor is limiting for you, and how to build humus in a targeted, measurable and lasting way.

Fundamentals

What roots really do

Roots actively steer soil life. They release sugars, amino acids and signalling compounds into the rhizosphere, feeding specific microorganisms. The more diverse the plant community, the more diverse the microbiome – and the more stable the humus build-up.

Soil as an organism

When the system works, 1 + 1 becomes more than 2: nutrients become available, water is stored, carbon is bound.

Use cycles

Organic residues become resources. The soil regenerates itself – measurable and lasting.

Diversity decides

The more diverse the plants, the more diverse the microbiome – and the more stable the humus.
