“…Both P sources produced similar large increases in corn grain yield and considerable residual effects on soybean seed yield from the P that was applied the year before. Results from the first and second years of the corn–soybean rotation showed that there were no differences between the two P fertilizers and their effects on initial corn DM, P concentration and uptake, and grain yield (Thompson et al., 2013). Results also demonstrated that P availability from struvite in a corn–soybean rotation was comparable to that of TSP (Thompson et al., 2013).…”

Results also demonstrated that P availability from struvite in a corn–soybean rotation was comparable to that of TSP (Thompson et al., 2013). Although yield was not measured in this study due to terminating the study before the corn plants reached full maturity, cob‐plus‐husk (Table 6) and stem‐plus‐leaves tissue P concentrations (Table 7) from ECST were greater than that from CG and TSP, which suggests that corn yields would have been at least similar, perhaps greater, from ECST than yields from CG and/or TSP.…”

Recycling P from wastewaters may provide a sustainable source of P that could also protect surface water quality from P enrichment. Struvite (MgNH 4 PO 4 ⋅6H 2 O) is a material that can be created from P-containing wastewater and has been shown to have agricultural fertilizer value. The objective of this study was to evaluate the effects of electrochemically precipitated struvite (ECST), chemically precipitated struvite (Crystal Green, CG), diammonium phosphate (DAP), monoammonium phosphate (MAP), rock phosphate (RP), and triple superphosphate (TSP) on corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] response in a 79-d greenhouse pot study. Soybean aboveground dry matter (DM) and yield were unaffected by fertilizer-P treatments, but belowground, pod, and stem-plus-leaves tissue-P concentrations differed among fertilizer treatments. Total corn DM from ECST did not differ from that from RP and TSP but was 1.2 times greater than that from CG. Belowground corn DM from ECST was 1.9 times greater than that from CG, TSP, and DAP. Corn belowground tissue P concentration from CG did not differ from that from DAP, TSP, and MAP, but was 1.4 times larger than that from ECST. Corn cob-plus-husk tissue P concentration from ECST was similar to that from MAP and DAP and was 1.2 times greater than that from CG. Results of this study not only provide information on the relatively new ECST material, but also substantiate the need for additional research on struvite as a potential alternative fertilizer-P source and the potential impact on sustainable food production and water quality preservation.

“…In addition higher yields were obtained when using animal manures as a P source compared with equivalent amounts of mineral fertiliser (Reddy et al 1999(Reddy et al , 2000Whalen et al, 2000;Horta et al, 2014a). Experiments with struvite show that it's a source of P to crops with a P slow release effect which is a benefit for pastures (Thompson et al, 2012;Katanda et al, 2013;Cerrillo et al, 2015). Nevertheless to use struvite as a fertiliser is still needed more research to develop efficiency and scale of recovered struvite from sewage and to formulate appropriate fertilisers (P-REX policy brief, March 2015).…”

A B S T R A C TPhosphorus (P), which originates from a non-renewable natural resource, is essential for crop productivity, food security and human health. Despite being a finite resource its use has been increasing consistently over the last few decades. The major use of the phosphate rock is the manufacture of P fertiliser, agriculture also being the main source for nonpoint source P pollution, which causes the eutrophication of water bodies. Thus, there is great need for a sustainable use of P with special attention to agricultural use, namely P fertilisation. This paper explores P sources and forms that could be phytoavailable and hence used as fertilisers. Current trends in phosphorus fertilisation are also discussed with a focus on approaches to net decrease in phosphate rock exploitation and closure of phosphorous cycle use.Keywords: eutrophication, fertilisers, phosphate rock, soil test phosphorus, struvite R E S U M OO fósforo (P) provém de um recurso natural não renovável e é indispensável para a produtividade agrícola, segurança alimentar e saúde humana. Apesar de ser um recurso finito o seu consumo tem vindo a crescer nas últimas décadas. O principal uso da rocha fosfatada é a produção de adubos fosfatados sendo também a atividade agrícola, a principal fonte de P de origem difusa que causa a eutrofização dos cursos de água. Estes factos enfatizam a necessidade do uso sustentá-vel do P com especial atenção no seu uso agrícola, em particular na fertilização fosfatada. Este artigo aborda as origens e as formas de P que podem ser fitodisponíveis e, deste modo usadas como fertilizantes. São também apresentadas as atuais tendências para uma fertilização fosfatada sustentável, com referência a algumas práticas e tecnologias para alcançar não só uma real diminuição na exploração das rochas fosfatadas, com também para fechar o ciclo de utilização do fósforo.Palavras-chave: eutrofização, fertilizantes, métodos de quantificação do fósforo, rocha fosfatada, struvite History and evolution of phosphorus fertilisationPhosphorus (P) is an essential nutrient for living beings making up about 0.2% of a plant's dry weight. P enters in the food chain taken up by plant roots from soil solution. P is a component of key molecules such as nucleic acids, phospholipids, and ATP. Therefore is a component of many cell constituents and plays a major role in several key processes, including photosynthesis, respiration, and energy storage and transfer, cell division, and cell enlargement (Marschner, 1995;Schachtman et al., 1998). In addition to other functions animals also require P for bones and teeth and derive their phosphorus needs from plant products and feed supplements. Thus, an adequate soil P level is essential not only for crop production but also for food security and human health.

Wastewater‐recovered struvite evaluation as a fertilizer‐phosphorus source for corn in eastern Arkansas

The perception of wastewater as a resource rather than a pollutant has not been well emphasized. Phosphorus (P) can be precipitated from wastewaters as the mineral struvite (MgNH 4 PO 4 •6H 2 O), which can be a potential sustainable alternative to the limited, rock phosphate (RP)-dependent, traditional fertilizer-P sources for agricultural production. This field study evaluated the effects of electrochemically precipitated struvite (ECST) and chemically precipitated struvite (CPST) compared with other conventional fertilizer-P materials (monoammonium phosphate [MAP],diammonium phosphate [DAP], triple superphosphate [TSP], and RP) on corn (Zea mays L.) response in two consecutive growing seasons in a P-deficient, silt-loam soil (Aquic Fraglossudalf) in eastern Arkansas. Averaged across years, corn yield was numerically largest from ECST (12.9 Mg ha -1 ), which differed (P < .05) from all other treatments and was numerically smallest from DAP (10.1 Mg ha -1 ), which was similar to MAP (10.7 Mg ha -1 ), CPST (10.3 Mg ha -1 ), and RP (10.3 Mg ha -1 ). Corn yield and kernel P uptake from ECST were at least 1.2 times greater (P < .05) than from CPST, TSP, DAP, and RP. Yield from ECST was 1.2 times greater (P < .05) than from MAP. A partial budget analysis showed that, across both years, fertilizer-P treatment net revenues for ECST were greater than those associated with the other fertilizer-P sources. Results demonstrated that wastewater-recovered struvite materials have the potential to be a sustainable source of P for corn production in P-deficient, silt-loam soil from both a technical and economic perspective.
