“…Struvite (MgNH 4 PO 4 .6H 2 O), a mineral which can be precipitated from nutrient-rich wastewaters, has shown promise as a slow-release fertilizer of low water solubility and high phosphorus (P) effectiveness (Kataki, West, Clarke, & Baruah, 2016a;Tarayre et al, 2016;Weissengruber, Möller, Puschenreiter, & Friedel, 2018). Given that maximum yields are not achieved due to insufficient P on 40% of global arable land (Zhu, Li, & Whelan, 2018) as well as projected rising fertilizer cost and geopolitical considerations affecting the availability of rock phosphate ore deposits (Egle, Rechberger, & Zessner, 2015), struvite has attracted interest primarily as a potential P source.…”

Struvite (MgNH4PO4.6H2O) and nitrification inhibitors are applied to soils to, respectively, provide nutrients and reduce nitrogen (N) loss. Given its low N composition (5.7%) relative to that of phosphorus (P, 12.6%) and magnesium (Mg, 9.9%), struvite could be added to soil concurrently with N fertilizers as a source of P and Mg. Nutrient release from struvite could be impacted if nitrification of its ammonium component is reduced by a nitrification inhibitor. Accordingly, a pot trial gauged whether struvite‐fertilized ryegrass had comparable Mg or P uptake and shoot yields with treatments receiving conventional Mg and P fertilizers. Struvite precipitated from milk industry wastewater, or conventional fertilizers, were added to a soil–sand mixture of low fertility. The inhibitor dicyandiamide (DCD) was added to assess its effect on P uptake by ryegrass. Relative to Epsom salt, struvite led to increased Mg uptake without significantly affecting shoot biomass, indicating luxury consumption. Regarding shoot yield and P uptake, struvite was as effective as triple super phosphate. DCD significantly reduced P uptake in the first harvest; the inhibited nitrification of the ammonium is surmised to have diminished struvite dissolution. In later harvests, DCD led to a trend (albeit not statistically significant) of increased biomass; this N‐rich (66% N) compound was probably biodegraded and utilized as an N source. The impact of DCD on P uptake in this experiment was short‐lived. Nevertheless, DCD degradation occurs less rapidly in field conditions, potentially affecting early P supply which is vital for optimum yield.

“…It seems that utilization of phosphorus‐solubilizing organism both phosphorus‐solubilizing bacteria as well as phosphorus‐solubilizing fungi could mitigate the problem with the contamination of ground waters with the excess of phosphorus and at the same time improve quality of crops. Another approach that focuses on the use of microbial systems for phosphorus accumulation and recovery that can be found in the literature is the utilization of phosphorus‐accumulating organisms . The product—biomass with higher levels of phosphorus, after incineration can be used as well in the microbial solubilization.…”

This paper presents the results of in situ studies on solubilization of different phosphorus-bearing raw materials by application of natural ability to produce organic acids by Bacillus megaterium. Poultry bones as well as fish bones were used as renewable sources of phosphates. Morocco phosphorite was used as nonrenewable sources of phosphates. Glass columns, filled with the soil mixed with different doses (1, 5, and 10%) of mentioned sources of phosphorus, were used as a medium for solubilization. It was found that the amount of released phosphorus (determined in the eluent and expressed as P 2 O 5 ) significantly increased in the cases of columns where B. megaterium was used, when compared with the control group (without microflora). Higher doses of phosphorus-bearing material used in the experiment influenced in the release of higher amount of phosphorus. The highest effectiveness of solubilization was found in the case of poultry bones. The experiment was repeated for poultry bones but with the supplementation of nutrients. It was found that the delivery of nutrients had a strong effect on the increase of effectiveness of solubilization. Two times higher amount of phosphorus (express as P 2 O 5 ) was released from the hydroxyapatite structure of bones. It was confirmed that poultry bones could serve as a source of phosphates in microbial solubilization performed in in situ.

The Potential Phosphorus Crisis: Resource Conservation and Possible Escape Technologies: A Review

Abstract:Phosphorus is an essential nutrient for every organism on the Earth, yet it is also a potential environmental pollutant, which may cause eutrophication of water bodies. Wastewater treatment plants worldwide are struggling to eliminate phosphorus from effluents, at great cost, yet current research suggests that the world may deplete the more available phosphorus reserves by around 2300. This, in addition to environmental concerns, evokes the need for new phosphorus recovery techniques to be developed, to meet future generations needs for renewable phosphorus supply. Many studies have been, and are, carried out on phosphorus recovery from wastewater and its sludge, due to their high phosphorus content. Chemical precipitation is the main process for achieving a phosphorus-containing mineral suitable for reuse as a fertilizer, such as struvite. This paper reviews the current status and future trends of phosphorus production and consumption, and summarizes current recovery technologies, discussing their possible integration into wastewater treatment processes, according to a more sustainable water-energy-nutrient nexus.
