In order to explore possibilities and barriers for waste based fertilizer products, we have completed interviews with farmers, possible suppliers and environmental NGOs

The first interviews with farmers have shown that: 

  • Most of the farmers have no principle opposition to using waste based fertilizer products
  • If it is practical to use and provide the same earnings as mineral fertilizer the farmers are interested in using it
  • Organic material in the soil is important for most of the farmers
  • The products should preferably be balanced with respect to nutrients
  • Important that using waste based fertilizer products do not imply increase soil compaction and increased tractor driving
  • No strong environmental or intrinsic motivation to use it
  • Some skepticism regarding uncertainty about the exact content of nutrients
  • Some skepticism to long term environmental risks from waste based fertilizer products from sewage and fish sludge from one of the farmers.
