On Gotland, we have a 350 m2 field trial growing barley that has been fertilized with dried urine (collected on Gotland in summer 2021 with TouchDown), mineral fertilizer or no fertilizer. This summer, we complemented the urine fertilizer with mineral phosphorus to match the recommended fertilizer needs of malting barley. The fertilized plants are growing well, while the none fertilized plants are shorter. We will harvest in late August and test the grain quality.
