000826819 520__ $$aRecycling 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.
