A new study by Caroline Ganglo and Stefan Karlowsky from the Leibniz Institute for Horticultural Sciences (IGZ) investigated whether human excreta-derived fertilisers are suitable for replacing mineral fertiliser in kohlrabi production and how they affect plant N uptake and soil N fluxes. The results gained as part of the Horizon Europe Innovation Action “P2GreeN” underpin that a transition to circular nutrients flows and resilient local food production is possible without compromising food security. The study, titled “Application of nitrified urine fertilizer and faecal compost for growing kohlrabi in a controlled greenhouse environment”, was published in Frontiers in Environmental Science.
