Capturing and recycling phosphorus<\/strong> could help reduce risks in terms of availability and pollution. This is particularly relevant for Norway<\/strong>, whose government plans to expand salmon and trout production to 5 million tonnes annually from the current 1.5 million by 2050. This is the message from a new report<\/a> by the Norwegian University of Science and Technology in Trondheim<\/strong>, which emphasises the crucial role of phosphorus in national agriculture and aquaculture.<\/p>\n “Currently, large amounts of phosphorus enter the Norwegian food system from abroad in the form of mineral fertilizer<\/a>, feedstuff<\/strong>, food, as well as micro-ingredients for animal feed, mainly in salmon farming,” the report explains.”However, only a small fraction of this phosphorus ends up as food<\/strong> for humans, while the largest part accumulates in soil and water systems.”<\/p>\n
