In developed countries, recycling of phosphorus (P) is an important issue as P is a strategic raw material for agriculture and other production sectors. But, P is also causing environmental problems, for example eutrophication of surface waters and change in nutrients balance. Using the methodology of material flow analysis, main flows and stocks of P were quantified in the Czech Republic (CR) during 1961–2010. The P balance in the CR depends on the P import in mineral fertilizers (1 kg/(ca·yr)) and food and feed (1.5 kg/(ca·yr)). Significant P losses to the CR environment represent an untapped potential for recycling. For example, municipal sludge (0.4 kg/(ca·yr)) and bone meal (0.25 kg/(ca·yr)) could replace 70 % of P in applied mineral fertilizers. The CR recycling rate of P (68 % in livestock production, 21 % in food production, 10 % in human consumption) is below the European (EU-27) average. The present CR agricultural production still benefits from soil P reserves resulting from the previous application of high doses of mineral fertilizers prior to the 1990s.
