Trends in the balance and material flows of phosphorus in the Czech Republic.
 Hejzlar, Josef
In developed countries, many voices call for increasing the recycling of phosphorus (P) that is a strategic raw material for agriculture and other production sector; phosphorus is also causing environmental problems, for example. eutrophication. Using the methodology of material flow analysis, van Dijk et al. (Sci. Total Environ. 2016, 552: 1078-1093) quantified the main flows and stocks of P in 27 states of the European Union. The contribution presents and discusses data from that publication for the material flows P in the Czech Republic (CR) and compared with the EU. The P balance of CR shows the dependence on imported P through mineral fertilizers (1 kg/ca/yr), food and feed (1.5 kg/ca/yr) and also draws attention to significant environment losses and unused recycling potential. For example, municipal sludge (0.4 kg/ca/yr) and bone meal (0.25 kg/ca/yr) could replace 70% of the P amount in applied mineral fertilizers. P recycling rate in CR in comparison with EU-27 is below average (68% in livestock production, 21% in food production, 10% for human consumption). Agricultural production in CR still uses P reserves in the soil of mineral fertilizers in the past.
