Mykorrhiza im ökologischen Landbau Organic Eprints
Mäder, Paul; Viehweger, Anja; Koller, Martin; Wiemken, A.; Bruns, C.; George, E..
The mycorrhizal symbiosis plays a major role in plant nutrient acquisition, pathogen control and soil stabilisation in land use systems with a low input of external resources. The use of inocula of mycorrhizal fungi for the development of sustainable agricultural production systems in Europe is still scarce. Since it was found that even in organically managed soils and particularly in substrates mycorrhizas can be limited, a set of recently introduced commercial inocula and 10 pre-selected strains of mycorrhizal fungi were multiplied and screened under farm conditions. Poinsettia, Pelargonium, leak and strawberry were used as test plants, which were inoculated in the seeding or potting substrates. There was a strong interaction between mycorrhizal fungi...

Erweiterung des Entscheidungshilfesystems Öko-SIMPHYT zur Reduktion der Kupferapplikationen gegen Phytophthora infestans im ökologischen Kartoffelanbau Organic Eprints
Bruns, C.; Schulz, H.; Tebbe, C.; Racca, P.; Werren, Dagmar; Finckh, Maria R.; Kleinhenz, Benno.
An improved Decisions Support System (DSS) for the control of Phytopththora infestans in organic potatoes was developed in the frame of the CoFree Project. This work included as primary steps the development of an ontogenetic model (Simonto) based on the BBCH scale of potatoes, and its validation. Additionally, the soil mineral nitrogen dynamics in organic potatoes and nitrogen contents of tuber and leaves were modelled and integrated in the existing DSS Öko-SIMPHYT (www.isip.de). The DSS comprises a correction tool at BBCH 60 for the user to improve the quality of the prediction of potato growth and a termination of copper spraying when potential yield of 90 % is reached. This development was based on intensive data mining in existing data sets from...
