Possibilities of the Demonstration of neolithic agricultural methods
– Experiences and Results –
Dr. Rüdiger Kelm
Archaeological-Ecological Centre Albersdorf
Rotation-System of the Slash-and-Burn-Technique and the consequences for the landscape (modified after POTT 1990)
Slash-and-Burn in modern times: Museal Experiment in the Black Forest in Southern Germany (from KLEIN et al. 1996)
Starting the fire at the (relatively dry) „bush-roll“ in Albersdorf
Public Demonstration/guided tours
Direction of the wind
After Burning: Concentration of Charcoal on the ground
Positive Effects of the Burning for the fertility of the soil (Data H. Bitter, Landwirtschaftskammer Schleswig-Holstein)
vorher nachher
pH-Wert: 3,3 (saurer Nadelwaldboden) pH-Wert: 6,4
7 mg Phosphor je 100 g Boden 72 mg Phosphor je 100 g Boden
17 mg Kalium je 100 g Boden 58 mg Kalium je 100 g Boden
11 mg Magnesium 56 mg Magnesium je 100 g Boden
First results with Winter-Rye (Secale cereale spontaneum)
An effect which was not planned: Growing of Pteridium aquilinum
Development of the Temperature (in °C) when Burning (after VARESCH 1962)
Pteridium as Indicator for Slash-and-Burn in Northern Germany since the Neolithic (after DÖRFLER 2001)
Continuation of the Experiment
Manual Plucking of the Pteridium-plants on the fields
Cutting of the young Pteridium-plants (before July)
Regular Burning of the same field
Observing of the changes in the soil-fertility in the following years
Thank you very much for your attention!
