Gaten in schalterveen verbeteren vochtregulatie en productie

A dense peat layer (schalter) between 20–40 cm deep restricts soil moisture regulation and root penetration, impairing plant growth and soil health. This layer reduces capillary rise and permeability when dry, limiting water availability to shallow roots. At a Friesland dairy farm in Koufnidderig, a grid-pattern drilling technique using specialized equipment from Wageningen Plant Research was tested to restore subsoil and groundwater connectivity. Holes were filled with drilling or polishing soil, improving root access and stimulating soil life. Results show reduced compaction and enhanced productivity, with one plot treated at double drilling density. Earthworms and deep-rooting plants like cichorium showed improved activity and growth. The method avoids destructive tilling and preserves peat integrity.
