Abstract Mineral phosphorus (P) fertilizers support high crop yields and contribute to feeding the teeming global population. However, complex edaphic processes cause P be immobilized in soil, hampering its timely sufficient availability for uptake by plants. The resultant low use efficiency of current water-soluble creates significant environmental human health problems.

Transformation of Phosphorus during (Hydro)thermal Treatments of Solid Biowastes: Reaction Mechanisms and Implications for P Reclamation and Recycling

Environmental Science & Technology, Journal Year: 2017, Volume and Issue: 51(18), P. 10284 - 10298

Published: Sept. 6, 2017

Phosphorus (P) is an essential nutrient for all organisms, thus playing unique and critical roles at the food–energy–water nexus. Most P utilized by human activities eventually converges into various solid biowastes, such as crop biomass, animal manures, sewage sludges. Therefore, integration of efficient recovery practices biowaste management will not only significantly reduce dependence on limited geological resources but also runoff related water contamination issues associated with traditional waste strategies. This study reviews applications (hydro)thermal techniques treatment which can greatly facilitate in addition to volume reduction, decontamination, energy recovery. Research showed that speciation (including molecular moiety, complexation state, mineralogy) experience significant changes during treatments, are impacted conditions. Changes overall properties products alter mobility bioavailability P, subsequent reclamation recycling efficiency products. review summarizes recent progresses this direction, identifies challenges knowledge gaps, provides a foundation future research efforts targeting sustainable nutrient-rich biowastes.

Phosphate-Exchanged Mg–Al Layered Double Hydroxides: A New Slow Release Phosphate Fertilizer

ACS Sustainable Chemistry & Engineering, Journal Year: 2016, Volume and Issue: 4(8), P. 4280 - 4287

Published: June 9, 2016

The global phosphorus crisis provided impetus to develop fertilizers with better P use efficiency. We tested layered double hydroxides (LDHs) as slow release superior performance fertilize strongly P-fixing soils. Mg–Al LDHs varying M2+/M3+ ratios were synthesized NO3– forms and exchanged HPO42–. XRD XANES spectroscopy confirmed the identity of phosphate-exchanged LDH. Decreasing ratio, i.e., increasing anion exchange capacity, increased selectivity adsorption due charge density LDH layers. fertilization efficiency (Mg/Al ratio 2) was compared that a soluble fertilizer in two P-deficient soils, an acid weathered soil calcareous soil. P-LDH up 4.5 times higher than P. This likely related liming effect In soil, at low doses only 20% above P, whereas it lower high doses. These overall encouraging results warrant further studies on boundary conditions under which P-LDHs may outperform traditional fertilizers.
