HUMUS sapiens

This year we meet from 25.-27.10.2019 in the woods near Munich.

Please write to on which days you would like to be there (with or without accommodation), and whether you already have a topic / project idea in mind or would like to give a workshop.


Soil creation and regeneration requires a tightly intertwined and interwoven network of organisms and matter, from microbes to animals and plants. The crosstalk between all of those compounds enables seeds to sprout on fertile soil.

We believe that this diversity is always the key to creativity and innovation: HUMUS sapiens creates interdisciplinary crosstalk and collaboration from scientists, biohackers, artists and ecologists to farmers and gardeners, to share and build knowledge and tools for soil analysis and regeneration

The Global Hackteria Network , Gasthaus: Fermentation and Bacteria and the mikroBIOMIK Society gather their resources to rethink the way we deal with our mother earth.

Event overview


The retreat will take place from Friday noon, 25th October until Sunday 27th October evening.

Where - Hosting & Accommodation


The Projekt Draussen, also known as `Klause zum Schindergraben` is in the middle of the woods close to the Isar. In the upper floor under the roof is a cozy space where up to 20 people can be hosted in individual beds. From there you have access to a small terrace to enjoy a calm moment. There are more two smaller rooms with loft beds which have access to the balcony directed to the south from where you can see the little river and catch sun all day long. Feel free to bring your sleeping bag, bedsheets can be also available. You can also bring your tent and mount it in any place of the territory.

How to get there

Projekt Draussen is located about 30 km in the South of Munich in the woods and close to the Isar.

Schindergraben 1, 82544 Egling

By bicycle The bicycle tour along the Isar takes about 1-2 hours. There are the following possibilities:

  • You start with your mountain bike on the Isar, for example in Munich at the Wittelsbacherbrücke, and orient yourself on the bike tour "Munich - Kloster Schäftlarn".
  • Or you climb on your racing bike in Munich, choose an Isar site and orient yourself on one of these routes.

By public transport and walking

With the S-Bahn S7 direction Wolfratshausen you arrive from the Munich Marienplatz either in 33 minutes to Hohenschäftlarn or in 36 minutes to Ebenhausen-Schäftlarn.

From the S-Bahn station Ebenhausen-Schäftlarn, you can prepare for an Isar walk: route

If you need a Shuttle please send us an email! (

By car

From Munich it takes about 30-40 min to reach Projekt Draussen by car following A95 or B11.

Projects, Presentations & Discussions

Liquid carbon pathway (discussion)


How does carbon get into the soil?
How do plants influence humus production?
How can we enhance the liquid carbon pathway?

Root scanner



We build several Wurzelfenster ('root windows') in different formats.
IMG 2886.jpg

Lukas also configured a scanner to record some timelapses.

-> Malte und Olga were able to build two "wurzelfenster" with Lukas. Malte plans to use it to display mycorrhizae interactions with plants perspectively.

Mycorrhiza and other symbiotic fungi


Malte was giving a presentation on the use of mycorrhiza for gardening and agriculture.

We are now planing to collect and compile comprehensible instructions for using mycorrhiza in your garden. Stay tuned. :)

Workshop "Mikroskopie mit dem Handy" - Matthias Burba (Mitschriften von Malte Larsen, bitte gerne ergänzen)

Es gibt 2 grundlegende Systeme, endlose und endliche. Die Adapter müssen verschieb/verstellbar sein um den nicht-optimalen Fokus des Handys optimieren zu können. Der Autofokus muss durch eine App blockiert werden (Es gibt verschiedene Apps die sich bei Android und iOS unterscheiden, Namen leider nicht mitgeschrieben). 6-8 MP Auflösung sind mit einem billigem iPhone möglich (ca. 50€). (Nicon Coolpix wäre eine gut Kamera) Tubushalterungen sind online verfügbar für Handy oder Kamera. Ein externer Monitor zur Bildgebung während der Arbeit ist sehr komfortabel.

Aus Wisconsin gibt es 3d gedruckte Mikroskope mit Glaskugeln als günstige Objektive. ( Eine dezentrale Lösung für Citizen Science.

"GPS Kamera" Software zur Speicherung definierter Metadaten in oder auf Fotos: Geschlossenes System zur Klassifizierung von Fotos, erleichtert es bei vielen Aufnahmen den Überblick zu behalten.

Eine Färbeanleitung findet man in der Mikrogruppe auf der Homepage vom Verein für Naturkunde Hamburg für Pilze.

Regenerative Agriculture


by Hellmut

CO2 Chamber


The CO2 Soil Respirtion Chamber can be used to measure the gas exchange between the soil, plants and atmosphere, as well temperature, pressure and humidity. The goal was to introduce simple techniques to help people understand biochemical cycles such soil respiration caused by microbial actvities or change of conditions by climate change. Also the data can be displayed and collected in a databank with a mobile app and be pushed threw the web for everybody to see and analyze. The next step for the CO2 chamber is to make it more easily accessible by making a new design that is a low cost and open hardware.

Citizen Sensor

Robert Meisenecker presented a new prototype of the citizen sensor and introduced us into the technology. He also gave us some valuable insights about the challenges during this cooperation between Fraunhofer Institute and FabLab Munich.

Julian Chollet

Julian Chollet.jpg

Julian is a (no)mad scientist, curious student and informal teacher with a background in molecular biology. He is working on the endless and underexplored biodiverity of microbes, fungi and phages - with the aim to liberate the world from microphobia through workshopology, fermentation and microscopy. His current main project focuses on creative learning environments and public participation in science with emphasis on the invisible world.
