News and Blog

At SoilSteam, our focus is on one thing: soil health.

We believe in a better way to keep soil healthy. We know that if we can restore health to our soils, we are restoring our soils to health. In less than 20 years, SoilSteam has evolved from a hobby project devised to satisfy the curiosity of three Norwegian farmers, into the professional technology company it is today. We are still a small Norwegian company, but we know we can contribute to make the world a better place.
