For stockless organic farms an adequate nutrient supply is in many ways a challenge. In order to assess the nutrient management of Austrian organic stockless farms, farm gate-balances for nitrogen, potassium and phosphorus of 15 organic stockless farms located in Austria’s main arable production areas were calculated. Two of the farms were located in Wald- und Mühlviertel (Northern Upper and Lower Austria), two in the Carinthian Basin (Carinthia), two in the Pre-alpine Region (Southern Upper and Lower Austria), two in the South-Eastern Lowlands (Eastern Styria and Burgenland), four in the Marchfeld region (Eastern Lower Austria) and three in the Weinviertel (North-Eastern Lower Austria). The farms were managed according to organic farming guidelines for at least five years at the time of assessment. Nutrient balances were calculated over a period of five years, subtracting all farm outputs (nutrients in sold products) from all farm inputs (seeds and fertilizers, biological N fixation). Yields were assessed in questionnaires from the farmers, nutrient contents were taken from standardized tables.
