Abstract:
In a long-term field trial in Therwil, Switzerland, the bio-dynamic, bio-organic and conventional farming systems were compared (DOC trial). The present paper focuses on long-term yield development and on product quality of beetroot. Due to the favourable climate and soil, beetroot yields were generally high. The yield of beetroot in both biological systems was about 75 % that of the conventional system, but the input of nitrogen and potassium was about 60 % lower.
