Exploitation of natural resources to increase soil health: BIO-INCROP, a project on organic fruit tree cropping systems Organic Eprints
Manici, L.M.; Baab , G.; Canet, R.; Kaymak, S.; Kelderer, M.; Insam , H.; Naef, A.; Pinar, H.; Rühmer, T; Whittle , I..
Introduction The vast majority of apple production in Europe takes place in intensive orchards, this implies the need for intensive capital investment for support structures which then have to be used for a number of generations of trees. Consequently new orchards have to be replanted in the same place as previous plots. This causes soil sickness or yield decline of which “replant disease” is the main biological component. Resulting yield losses are difficult to assess; a recent study in South Tyrol, where 12% of total EU apple is produced, showed that growth reduction can vary from 20 to 60% in replanted orchard compared to fallow control. Severity of this etiology is mediated by plant vigour, physiological state of plants and abiotic factors. Therefore,...

Relationship between root-endophytic microbial communities and replant disease in specialized apple growing areas in Europe Organic Eprints
Manici, L.; Kelderer, Markus; Franke-Whittle , I-H; Rühmer , T.; Baab , G.; Nicoletti , F.; Caputo, F.; Topp, A.; Insam , H.; Naef, A..
Apple replant disorders are one of the causes of the downward trend of land planted with apple orchards in Central Europe. A specific transnational survey was thus conducted on apple root associated microorganisms, aimed at increasing the knowledge regarding crop management to counteract this tendency. Soil health was evaluated using a bioassay test with root cuttings of the clonal M9 rootstock, one of the most commonly used rootstocks in Europe. Plant growth response in replant, fallow and gamma ray-sterilized soil was evaluated using soil samples taken from nine orchards selected (three per country) from specialized apple growing areas of Germany, Austria and Italy. Plant growth significantly differed between treatments but not between countries. Root...

Rhizosphere bacteria and fungi associated with plant growth in soils of three replanted apple orchards. Organic Eprints
Franke-Whittle, I.; Manici, L.; Insam , H.; Stes, B..
Background and aims: High-throughput 454 pyrosequencing was applied to investigate differences in bacterial and fungal communities between replant and closely situated control non-replant (fallow) soils. Methods The V1-V3 region of the bacterial 16S rRNA gene and the ITS1 region of fungi from the different soils were sequenced using 454 pyrosequencing (Titanium chemistry, and data were analysed using the MOTHUR pipeline. Results: The bacterial phyla Proteobacteria, Actinobacteria and Acidobacteria dominated in both fallow and replant apple orchard soils, and community composition at both phylum and genus level did not significantly differ according to NP-MANOVA. The fungal phyla Ascomycota, Zygomycota and Basidiomycota were dominant, and communities...
