The international joint project CLOOP was designed to demonstrate that in practice, mineral nutrient recyclates have higher use efficiencies than conventional fertilizers. This is crucial to ensure the protection of surface waters and an efficient use of resources. The project focuses on testing a new generation of secondary fertilizers (NextGen fertilizers) that feature high plant availability and low water solubility at the same time.
