Summary

Steaming of substrate and superficial steaming of the soil for weed regulation is allowed. Deep steaming (sterilisation) of the soil requires approval by BIOLAND. (Bioland production standards, 5.1.3 Steaming Surfaces and Soil; Bioland production standards, 5.8.3 Plant Health and Regulation of Weeds)

Difference

The BIOLAND standard is more detailed. The EU Regulation 2092/91 allows flame weeding to reduce weed pressure, but does not refer to deep steaming (sterilisation) of the soil.

Justification

Deep steaming for sterilisation impair soil biodiversity. Therefore it should only be used as a last resort for severe problems.
