Abstract:
Phosphorus (P) is essential for all forms of life and has a crucial role in environmental
systems. P is essential for food production as it is a major nutrient element limiting
plant growth. Agriculture depends on P derived from phosphate rock which is a
depleting non-renewable resource and often contaminated by heavy metals
(cadmium & uraium). Thus, the expected future P-fertilizer production from noncontaminated phosphate rock cannot meet the demands of a sustainable worldwide
food production. In consequence strategies are needed to facilitate the usage of
alternative P sources and to close the agricultural P cycle. These strategies
essentially are based on knowledge of P species cycling in agro-ecosystems
because distinct P species exhibit unique fates in the environmental. The workshop
intends bringing together experts and young reseachers applying innovative methods
for P speciation in soil and soil-related samples (1D & 2D NMR, XANES/EXAFS,
Nano-SIMS, isotope ratios, DGT).
