| The plant and animal health care strategy in organic farming strengthensagro-biodiversity, protects the environment as well as animal and human health. In addition to fully exploiting preventive options, the use of external inputs such as plant protection products, fertilisers or veterinarymedicinal productsis allowed to prevent inacceptable losses in productivity or animal suffering. However, external inputs need to comply with organic standardsas well as European legislationand aretherefore carefully evaluated before any decision on acceptance is taken.Organic farming systems should aim at reducing dependency on off-farm fertilisers to the lowest feasable level to ensure closed nutrient cycles and avoid nutrient leakage and contamination. This policy... |

| Die Spatenprobe liefert wertvolle Informationen zum Zustand landwirtschaftlicher Böden. Trotzdem wird sie in der Praxis wenig angewendet. Die BodenDok Mobile-App will dies nun ändern. Die App des Forschungsinstituts für biologischen Landbau FiBL,eine Co-Produktion mit der Fachhochschule Nordwestschweiz FHNW, unterstützt die Landwirte bei der Spatenprobe und weitergehenden Beobachtungen am Boden. Die App führt die Nutzer Schritt für Schritt durch den Beurteilungsprozess und liefert unter anderem Hinweise zur Bearbeitbarkeit des Bodens. Die App ist modular konzipiert, so dass vertiefende und innovative Untersuchungsmethoden zu einem späteren Zeitpunkt ergänzt werden können. |

| Phosphorus (P) in sewage sludge holds the main proportion of P currently lost in waste streams, and options to recycle it for agriculture are needed. Pyrolysis is a promising local alternative to centralized sewage sludge incineration. Pathogens and organic pollutants are destroyed and a carbon-rich substrate known as biochar is formed. We evaluated pyrolysis of sewage sludge as well as sintering of pyrolysis char with alkali salts. The products were applied in a pot experiment with calcareous and acidic soils to determine P uptake by ryegrass (Lolium multiflorum) and changes in soil pH, available P and cation exchange capacity. Two products were also tested in a field experiment with maize (Zea mays) on a neutral soil. Cadmium and mercury were partly... |

| Inoculation with phosphorus (P) solubilizing bacteria is being proposed to increase P availability for plants by mineralization and solubilization of non-available soil and fertilizer P. Solubilization of inorganic P compounds by bacterial strains has repeatedly been shown on agar plates and in liquid media. However, the effects of inoculation on P availability to plants growing in soils, either in pot or field studies, are inconsistent and do not allow to separate between direct effects on P availability and indirect effects such as improved plant health. This differentiation could be achieved using 33P isotopic labeling. We applied the 33P isotopic dilution method in a pot and in an incubation experiment to study gross P fluxes in a calcareous soil... |
