We replace the artificial turf with grass on three mini football pitches and test whether biochar can help us with more hours of football and less maintenance.
Artificial greens release microplastics that damage our oceans. At the same time, we want many playing hours without wearing too much on the surface.
We are now testing replacing an artificial turf with a turf that is built up with biochar.
Biochar is a product that is produced by burning organic plant parts, in this case residual products from seed cleaning, in an oxygen-free environment. In this process, pyrolysis, stable soil improvement products are formed with a large volume for water and nutrient management.
The biochar is then mixed with sand, instead of as today with peat soil. This culture material is then laid on a drainage gravel and the drainage gravel rests on a rubber cloth. We then get to a closed system where we can reuse water and minimize plant nutrient leakage.
Can we get a grass that can withstand more wear and tear and grow longer in the season? We'll find out!
