Das Projekt hatte zwei Fragestellungen: 1) Einfluss ökologischer Kulturführung von Mutterpflanzen (Pelargonien, Poinsettien) auf Qualität und Gesundheit der Stecklinge. 2) Integration und Effekte einer Inokulation mit arbuskulären Mykorrhizapilzen. Die Ergebnisse lassen sich wie folgt zusammenfassen: 1. In einem moderat aufgedüngten komposthaltigen Substrat mit entzugsorientierter organischer Stickstoffnachdüngung (System 1) waren Stecklingsertrag und Bewurzelungserfolg so gut wie bei konventioneller Kultur. 2. Eine am Gesamtbedarf der Mutterpflanzen orientierte höhere Aufdüngung (System 2) verursachte im warmen Sommer 2003 durch Mineralisierung eine Stickstoffüberversorgung und Salzbelastung, die das Wachstum reduzierte. Diese Kulturvariante... |

The demand for organically raised tree and hedging plants had been reported from organic farmers in Tir Gofal, as well as within the landscaping industry. Although there are a number of plant raising nurseries producing organically raised plants for vegetable and fruit production, there are no tree nurseries producing to organic standards. Nursery tree growers were concerned that there was currently too little known about the performance of tree seedlings in organic substrates (e.g. in root-trainers), nor about the nutrient supply to seedlings under organic regimes, nor about diseases control (especially fungal diseases such as mildew). Therefore, the development of three hedging species; Hawthorn, Hazel, Blackthorn, were tested for two growing systems in... |
