| Biogas production is a key technology for sustainable use of biomass from agricultural production. An optimisation of biogas production from energy crops should not confine to the consideration of the biogas process. To assure a durable success, cropping of energy plants has to be designed according to the principles of sustainable crop rota-tions. Only in site-adapted and ecologically balanced crop rotation systems, energy crop production is meaningful. The general aim of this study was to develope site-adapted crop rotation systems including energy crops as main and catch crops. Study regions were chosen to represent large regions of Austria. To include a great share of the crop species relevant for Austria, sites from the dry region (NUTS III region... |

| The root length density, arbuscular mycorrhizal (AM) colonisation and the total AM root length density of 12 winter wheat cultivars have been studied at seven sites in eastern Austria under organic farming. Root length density did not differ between the cultivars whereas AM colonisation and total AM root density did. Site effects were more pronounced than cultivar effects. All three traits generally were on a higher level in calcaric Phaeozems than in Cambisols. The AM colonisation and total AM root density decreased with increasing plant height and were positively correlated with crop yield. On calcaric Phaeozems, root length density in the subsoil was obviously more important for drought tolerance than AM colonisation in the topsoil. |
