Description

Artificial lengthening of vegetation periods by removing snow. Depending on the region, in March and April (in the mountains, end of April), still snow covered meadows and fields are sprinkled with soot and ash, so that the absorbed sunlight speeds up the snowmelt and allows for earlier cultivation.
