The topographically sound field site is on a gentle, north facing, slope in the valley of the «Birsig»stream. The annual mean temperature is 9.5 °C, the mean annual precipitation accounts for 792 litre per square metre. The soil is a haplic luvisol on alluvial loess of 0.9 to 1.3 meter depth.

The DOK-long term trial - unique in its conception - compares the consequences of bio-organic, bio-dynamic and conventional farming systems in a randomised plot trial that has no other equivalent. Experimental samples are used by many other laboratories to develop new methods in the areas of soil and food quality. The strategies of fertilization and plant protection are the main differences between the systems, whereas crop rotation and soil tillage were almost identical. The area where the DOK-trial is located, is documented to have long been in use as arable land (1957–1973 ley rotation, 1973–1975 field legumes and cereals, 1976 oats). In May 1977 the whole area was sown with grass-clover, and in the spring of 1978 the field experiment began with potatoes, spring wheat and spring barley.
