Abstract
The Stiftung Ökologischer Landbau (SÖL), founded in the mid-1970s, set out to promote organic farming in the Federal Republic of Germany (FRG). To this end, it brought together protagonists from the scientific community and the environmental movement to build a knowledge base for organic agriculture by drawing on the science-based concepts of natural and organic farming of the 1920s and 1930s. Based on the history of its founding, its structure, and work, this article demonstrates that temporality played an essential role in the establishment of alternative bodies of knowledge. Contrary to the established model of linear scientific-technological progress, the aim was to return to bodies of knowledge and practices that had largely disappeared from the scientific canon of knowledge, but also from agricultural practice, in previous processes of forgetting and marginalization. This is exemplified by the so-called "spade diagnosis," a method developed in the 1930s by soil biologists to assess arable soil. Concepts and practice of counter-knowledge amounted to a model of conservative modernization in organic farming.
