HUMUS sapiens: open soil research

The Global Hackteria Network , Gasthaus: Fermentation and Bacteria and the mikroBIOMIK society join forces to bring citizen science and the hacker spirit into soil ecology.
We are building a network of soil enthusiasts for long-term collaborative research and invite YOU to join us.

After our successful crowdfunding campaign (thanks!!) and a long summer of open soil research we now harvest the last fruits, watch how the ground freezes and digest all the new input Event overview

Birth of the HUMUS SAPIENS

In September 2017 an international and interdisciplinary crowd of curious minds gathered in a beautiful valley in the Swiss mountains: The Klöntal Biohack Retreat . Maya Minder and Marc Dusseiller invited interesting people from several European and Asian countries, to share their curiosity and common interest in the life sciences: together we created a place where Taiwanese bioartists, Swedish hardware designers, Indonesian architects and swiss biochemists - to name a few examples - converged to exchange ideas, develop projects and tinker with biology. Four intense days of exploring nature, sharing experiences, recipes, food, microbes, tools, etc.
One of the topics was: soil. Julian brought an old-school microscope and started to compare soil from his garden with samples we collected in the mountains. Amongst other things, the videos on this website were generated here. In the following days many different people used the microscope, went moss-hunting, tinkered with electronics and discussed about science, soil and society.

In January 2018 – during the Hackteria Futures Meeting in Zürich – we finally sat together again, made plans for a long-term collaboration on the topic of «open soil research» and planned this crowdfunding-campaign to kick-off our initiative.

About the open soil research events

04.05.2018 - 06.05.2018 Hackteria soil retreat

About 10 km outside of Schaffhausen (Switzerland), nested between the hills and woods just below 1000m of altitude - lies a comfortable little hut commonly known as Randelab. In the beginning of May, this was the setting for a special kind of gathering: the «Hackteria soil retreat» where scientists, biohackers, artists, makers, educators, ecologists and farmers came together to work on DIY methodologies and develop workshop concepts on the topic of soil ecology.
Special Guests: Lucy Patterson & Urs Gaudenz .

After a few intense days at Randelab some of the participants travelled to other locations in Europe to continue their work and share the inspirations from the retreat.

20.07.2018 - 22.07.2018 mikroBIOMIK soil retreat

About 30 km from Munich city-center, in the middle of pristine woods and right next to the river Isar, lies the hermitage ‘zum Schindergraben’, commonly known as Projekt Draussen ( http://projekt-draussen.com ). From the 20th to the 22nd of July the surrounding woods and waterways as well as the house itself became the setting for the «mikroBIOMIK soil retreat».
We gathered a colorful mix of experts from different disciplines, curious gardeners, skilled hobby microscopists and passionate artists. The event was flexibly structured (as a barcamp/unconference) to address as many questions and approaches as possible and to develop the program together with the participants. There were many discussions and networking sessions, but also a lot has happened in practice: excursions, microscopy, composting, electronic crafts, comic drawing, yoga, a jazz concert,...

Some of the questions we would like to ask:

1) What is humus?

The word originally just meant ‘earth’ and is related to homo (“human being”). This beautiful term alllows many different interpretations...

2) What is the difference between conventional and biological farmed soil?

Although there have been numerous studies and comparisons of soil health on conventional and organic farms, their methods often focus on chemical composition and are not easily accessible by interested individuals. Also, scientists and farmers are now getting more aware that microbial communities are the central players for soil health.
An interesting publication on the topic is found here .

3) How can we measure soil health with low-cost and open-source technology?

Humidity and soil respiration has been measured with simple self-made tools and microbial diversity can be estimated with the help of microscopy. Hackers and tinkerers all around the world have been working on soil ecology for many years. We will start to collect these ideas and use them as a basis for further experiments and protocol development.

4) How does microbial diversity influence plant growth?

Healthy soil has a high diversity of microbial and invertebrate (e.g. earthworm) activity. It is not very well understood how these organisms influence plant growth and the nutritional quality of the resulting crops. We do not expect to answer these questions within the scope of this project but we might be able do develop new strategies and tools to catalyse further research.

5) Can we measure the impact of using chemicals (e.g. glyphosate) on our soil?

The widespread use of glyphosate/roundup and other chemicals in agriculture is under fierce debate at the moment. Is there a way for us to constructively contribute to the science behind the politics by providing an easier access to the study of soil ecology?

6) How can we expand and share this knowledge efficiently?

Open access publication, wikis, and workshops are an established and successful way of spreading knowledge and experience. But how do we reach people who rarely use the Internet?
