      abstract     = {Recycling of phosphorus (P) from waste materials is an
                      important approach to develop sustainably an efficient and
                      clean fertilizer for many countries with no phosphorus rock
                      deposits.We evaluated the P fertilizing value of struvite, a
                      precipitate traditionally recovered from waste water
                      treatments. We investigated how the P availability differs
                      between 1) two plant species, Zea mays and Lupinus
                      angustifolius, employing different nutrient acquisition
                      strategies, and 2) two different forms of nitrogen (N)
                      fertilizer: ammonium and nitrate which causes respectively
                      rhizosphere acidification or alkalization. We had a
                      non-fertilized and a with triples-superphosphate (TSP)
                      fertilized controls. Plants were grown on an acidic sand in
                      the greenhouse.Struvite had as high P recovery (P uptake/P
                      applied) as TSP. In both species fertigation with ammonium
                      resulted in a significantly greater P uptake (g/root surface
                      area), but not greater total uptake as plants fertigated
                      with nitrate had greater root surface area. Possibly
                      ammonium uptake resulted in rhizosphere acidification and
                      thereby greater mobilization and uptake of P.We propose that
                      struvite can be used as a sustainable phosphorus fertilizer
                      on acidic sandy soils.},
