Peat reduction and the change to alternative constituents in horticultural growing media (substrates) is a major challenge for the production of woody plants in pots (container stock). The proposed model and demonstration project is intended to show, that high-quality plants can be produced even in substrates that are highly peat-reduced. Accordingly, the project should serve to reduce barriers for the commercial nurseries, support the step-by-step implementation of peat-reduced substrates in practice and thus improve the acceptance of alternative substrates in hardy nursery stock. In the two model regions Ammerland and Pinneberg, nurseries are to be integrated which represent as far as possible the entire spectrum of container crop production. Based on the previous studies on substrates with alternative constituents in the nursery, the most promising substrate mixtures will be used for selected plant species. The peat content is to be a maximum of 50 % and is to be reduced to a minimum in the course of the project, depending on the specific conditions of the nursery and the plant species. In addition, the aim is to test completely peat-free substrates for selected crops. A scale-up, the integration of further crops and substrate mixtures as well as the optimisation of the cultivation methods are planned for the further vegetation periods. The changes in crop management, plant quality, crop risk and material input resulting from the substrate conversion will be documented for selected sample crops and subsequently used for an economic evaluation. Within the framework of the project, close cooperation with the advisory services and the substrate industry is planned. In order to make the project results available to a broad public, so-called 'field days' are planned in selected nurseries in addition to classic lecture events and publications. Furthermore, digital media are to be used more intensively and teacher training courses are to be carried out.
