The Service Center for Rural Areas (DLR) Rheinlandpfalz (Rhineland-Palatinate) has published the latest research results on steaming of field salad cultures in greenhouses.
In the end of 2010 an area of 600 sqm were treated down to 10 cm depth with the latest steaming system “Steam Mixer”, invented by Mobildampf. The output of the steaming system reaches up to 1000 kg steam per hour at about 180sqm / h.
All results are in favor of steaming. While the untreated control area only had a yield of merely 560gr sqm of fresh mass and was infested by weed, the area treated with hot steam was completely weed-free and yielded 700gr/sqm – an increase of about 25%.
