  1. Organic Fertilization of Red Raspberry cv. ‘Glen Ample’, in Polyethylene Tunnels in NorwayBy Rolf Nestby: Norwegian Institute for Agricultural and Environmental Research, Grasland and Landscape Division, Kvithamar, 7500 Stjørdal, Norway. Ingrid Myrstad:The Norwegian Agricultural Extension Service (LFR), 9410 Borkenes, Norway.

  2. Challenges and frames of theproject • Experiments in fields at 62 , 65 and 68 °N • Thesefields have verydifferentsoils. • Challenge to cover nutrientneedswithorganicfertilizers, especiallyconsideringfertigation. • Project period 2007 to 2010. • Financed by theNorwegian Research Council • Fertilization is one of fourobjectives of theproject.

  3. The field at 62 °N , Innvik, Norway Mineral soil - pH 5.7 P-K-Mg-Ca: 23.9 5.2 7.2 107 (Al-methode)

  4. The field at 65 °N , Brønnøysund, Norway Mineral soil – pH 7.7 (sandy loam) P-K-Mg-Ca: 12 10 330 9000

  5. The field at 68°N, Harstad, Norway. Mineral soil with 40% organic matter P-k-Mg-Ca: 44-29 33-12 76- 67 426-369

  6. Potassium deficiency at 68 °N Summer 2007

  7. Management Fertilizers Levels of N 9, 13,17 Other macro nutrients are balanced to level of N. Solid fertilizer are given in spring and mid summer. Fertigation from mid summer to end of harvest. • Agromarin – Based on organic material from Marin and Agriculture sources. (6.5- 4-4) • Marihøne Pluss – Based on bone powder and vinasse (8-3-3). • OASE for fertigation (8-4-6)

  8. Conclusion • Registrations in 2007 showed small effects in growth and yield. • Deficiency symptoms observed in two fields (K, Mn, Fe). • Only one field was fully grown in 2007. • The experiments 2008-2010 will be better balanced. • Testing of fertilizers for fertigation will be undertaken
