Knicks are banks planted with shrubs and dense stands of trees and they border fields and pastures In Schleswig Holstein they are typical features of the landscape and they have great importance for nature conservation Knicks are coppiced every 10 15 years with some individual trees left standing standard trees The wood harvested from knicks is often used for the production of energy But what is the yield and when is the best time to harvest the wood A means of achieving reliable forecasts of yields from knicks has been developed using aerial photographs of knicks A 3D model was calculated from the images and later correlated to the actual yield RESULTS The studied knicks were found to have a dry mass yield of 20 4470 kg 10 m length 810 on average This includes the standard trees whose mass was estimated The average annual growth of the studied knicks was 0 52 kg of dry matter m per year in relation to the crown area 1 m3 of knick in the form of the space taken up by trunks and branches provides an average of 1 2 kg of dry wood mass standard trees included The composition of the tree species orientation management and soil properties had no influence on wood yield or calorific value The value of knicks for nature conservation increases with higher biodiversity the width of the woodland scrub and its edge It emerged that a rule of thumb estimate of the yield is very close to the forecast from complex calculations 1 m3 of knick vegetation 1 kg of dry wood mass FINAL REPORT www eip agrar sh de eip innovationsprojekte FILM https www youtube com watch v O5BonprKf5g feature youtu be CONTACT PERSON Prof Dr Eberhard Hartung phone 49 431 880 2107 ehartung ilv uni kiel de und Dr Eiko Thiessen phone 49 431 880 3790 ethiessen ilv uni kiel de PLENTY OF WOOD IN THE KNICKS Sustainable use of biomass Knicks sind Wallhecken die Felder begrenzen Durch Überfliegen und Bildaufnahmen konnte der erwartete Holzertrag berechnet werden NACHHALTIGE BIOMASSENUTZUNG SUSTAINABLE USE OF BIOMASS Projektlaufzeit Project duration 1 6 2015 31 8 2019 TEILNEHMER PARTICIPANTS Landwirtschaftliche Betriebe Agricultural businesses AGRICOLA GbR Gut Rixdorf Lebrade Wilken von Behr Thomas Bock Schellhorn Christian Sieh und Volker Hennings Theresienhof NaturEnergie Konzept GmbH Steinfeld Sönke Martensen Be triebsgemeinschaft Grünhaus GbR Kirchnüchel Henning Südel Papke Schumacher GbR Malente Frank Schumacher und Christian Papke Boßmann Energie GmbH Co KG Bujendorf Hubertus und Christiane Boßmann Bio Power Service GmbH Co KG Bordesholm Garloff Langenbeck Waldeck Eiderhof KG Lehe Thorben Holsteiner Pentzlin landtechnisches Lohnunternehmen Schönwalde Klaus Pentzlin Unternehmen des vor und nachgelagerten Bereichs der Landwirtschaft Upstream and downstream agricultural companies Landesverband der Lohnunternehmer in Land und Forstwirtschaft SH e V Rendsburg Hans Jürgen Plöhn Niels Schäfer Forschungs und Versuchseinrichtungen Research and test facilities Christian Albrechts Universität zu Kiel Institut für Landwirtschaftliche Verfahrenstechnik Prof Dr Eberhard Hartung Fachhochschule Kiel FB Agrar La nd sc ap e m an ag em en t Pl an t pr od uc ti on 40
