Cultivation tests with recirculated fertiliser products

Do you have a residual product from any type of process that you think could be used as a fertiliser or growing medium in food production? RISE offer a test environment where recycled products are evaluated in crop experiments.

There are increasing demands for recirculation of plant nutrients from different parts of society, including sewage plants, back to arable land. For recycled fertiliser products to be accepted in agriculture, and to ensure that high-quality products attractive for agricultural use are produced, the usability and safety of the products need to be assured. Plant nutrient content, plant availability, unwanted substances, and pH effect in the soil is important information for farmers and vegetable growers. The complex structure of many recycled products means that their function can vary widely between different soil types. RISE offers a test methodology based on chemical analyses, soil incubation- and cultivation experiments, which in the future may be used in a certification system. We also arrange tests in a field environment.

More information

We can help you with professional tests that provide information on the functionality and safety of fertilisers containing nutrients recovered from nutrient-rich waste streams from society.

We evaluate residual products for their use as fertilisers or as growing medium.

We offer cultivation tests in green house as well as in field environment, and analysis of e.g.:

  • Nutrient content
  • Plant availability
  • Heavy metals
  • Organic contaminants (e.g. PAH/PCB)
  • Spreader properties (for fertiliser products)
  • Water holding capacity (for growing medium)
