The solutions are in the soil!

On July 12 through 14 2019 Marc Siepman will give a course on soils at Provision in Alunişu, Romania. Marc Siepman lives in The Netherlands and has given over 130 courses and over 200 lectures since 2013.

During this course you will meet several important inhabitants of a healthy soil: bacteria, fungi, protists, nematodes, earthworms, and more. What’s their purpose? How do they relate to each other? And more importantly: how can we help them so they can do their important work?

Although soil life is infinitely complex, taking care of it is not. We must learn to trust the complexities and team up with all life.

Although we need healthy soils for the health of plants, animals and even the planet, we lose soils at breakneck speed. Agriculture causes desertification, erosion, deforestation, pollution and the degradation of life in general. Planet Earth is losing its biodiversity at a rate of about two hundred species per day and her climate is increasingly erratic.

Problems abound, but many solutions can be found in the soil!


The course will be in English, but is not my mother tongue. We will help each other if I can’t find the right words or someone doesn’t understand what I’m trying to say.


Marc generally works for free, living on donations with his wife and son. But to cover travel expenses and meals, we need to charge a fee of 230 RON per person, which we call the “balanced fee”, since this will just cover costs if we have 10 participants. If you cannot afford this, please contact us and we might be able to offer you the “basic fee” of 130 RON. These spaces will be co-created when others, who have more access to financial resources, pay the “community fee” of 330 RON.

  • Basic fee = 130 RON
  • Balanced fee = 230 RON
  • Community fee = 330 RON
