“…Some authors reported different rates of P released from struvite due to edaphic properties and crop characteristics, Table 3. Olsen P (mg kg -1 soil) of all treatments during the incubation time such as root exudates (González-Ponce et al, 2009;Ackerman et al, 2013;Katanda et al, 2016;Talboys et al, 2016). Ackerman et al (2013) found lower production of biomass per unit of P from struvite, compared with MAP and PCMAP, due to a lower initial solubility of struvite in the alkaline soil used.…”

“…Similarly, González-Ponce et al (2009) found a higher lettuce yield due to the beneficial effects of Mg content of struvite compared with SSP treatments. Moreover, according to Talboys et al (2016), the presence of high amounts of organic acids exuded by buckwheat roots (Fagopyrum esculentum Moench) improves the P solubility of struvite, compared with T. aestivum, which did not exude large quantities of organic acids. The high P uptake and use efficiency of rye, as also observed by Osborne & Rengel (2002), partially explains the use of P from forms of lower availability (Kochian et al, 2004).…”

“…Livestock slurries and anaerobically digested effluents in wastewaters are good sources of struvite due to their concentration of N and P. Struvite is a crystalline substance consisting of magnesium, ammonium and phosphorus in equal molar concentrations (MgNH 4 PO 4 .6H 2 O) that can be used as P fertilizer or as a raw material for fertilizers (Rahman et al, 2014;Talboys et al, 2016). The use of composts as fertilizers has many advantages over the direct application of sewage sludge and livestock effluents to the soil, since composts are stabilized, have humified organic matter, are free from pathogenic organisms and provide nutrients, including P, to crops (Fuentes et al, 2006;Stutter, 2015).…”

“…(Frossard et al, 2002). Struvite has been considered as an efficient P fertilizer and it is commonly reported as a slow-release fertilizer, based on the presence of low-solubility P forms (Ackerman et al, 2013;Talboys et al, 2016). This study evaluated the type and fractions of P forms in struvite and in two composts of different origins.…”

A B S T R A C TThe objective of this study was to assess the type and fractions of phosphorus (P) forms in composts and struvite and how these P forms affect the bioavailability of P in the soil. P fertilization was performed with compost from sewage sludge (CSS), compost from poultry litter (CPL) and struvite (SV) and compared with single superphosphate (SSP). P forms were quantified through a sequential fractionation scheme. The first extraction was performed with H 2 O, the second with 0.5 M NaHCO 3 , the third with 0.1 M NaOH and the fourth with 1 M HCl. The release of P over time, after soil P fertilization, was assessed by incubating the fertilizers with a low-P acid soil. P bioavailability was assessed through a micro-pot experiment with the incubated soils in a growth chamber using rye plants (Secale cereale L.). Inorganic P forms in the first two fractions represented ~50% (composts), 32% (SV) and 86% (SSP) of the total P; and in the HCl fraction, ~40% (composts), 26% (SV) and 13% (SSP) of the total P. Despite the variability of the P form fractions in the composts and struvite, the P release and bioavailability were similar among the fertilized treatments. The acidic nature of the soil, which improve solubility of Ca-P forms, and the high efficiency of rye, which favors P uptake, were factors that contributed to these results.Biodisponibilidade do fósforo em compostos e struvite aplicados em solos ácidos R E S U M O O trabalho teve como objetivo caracterizar as formas de fósforo (P) presentes em compostos e em struvite e avaliar a influência dessas formas na biodisponibilidade do P. A fertilização fosfatada efetuou-se com composto obtido de lodos de tratamento de águas residuais (CSS), composto a partir de estrume de galinha (CP) ou struvite (SV) utilizando-se o adubo comercial superfosfato simples (SSP) como controle. Realizou-se um fracionamento sequencial das formas de P dos fertilizantes: a primeira extração efetuou-se com H 2 O, a segunda com NaHCO 3 0,5 M, a terceira com NaOH 0,1 M e a quarta com HCl 1 M. Realizou-se um ensaio de incubação após aplicação de cada fertilizante a um solo ácido e pobre em P para avaliação do efeito do tempo na libertação do P. A biodisponibilidade de P foi avaliada num ensaio em vasos com os solos incubados usando como planta teste o centeio (Secale cereale L.). Os compostos apresentaram ~50% do P inorgânico nas duas primeiras frações, a SV 32% e o SSP 86%. A fração de P inorgânico em HCl representou ~40% nos compostos, 26% na SV e 13% no SSP. Apesar da variabilidade nas formas de P todos os fertilizantes mostraram semelhante taxa de libertação e biodisponibilidade em P. A acidez do solo, favorecendo a solubilização de formas de P, em conjunto com a elevada eficiência do centeio em absorver o P, foram fatores que contribuíram para este resultado.

“…An alternative to mined P is the use of struvite (MgNH 4 PO 4 AE6H 2 O) recovered from wastewaters (Rahman et al 2014;Talboys et al 2016). Although demonstrated to act as an effective slow-release source of P for plant growth, struvite is not widely used as a fertilizer material.…”

Mineral resources are fundamental to the growth and development of human society. Extraction of metal ores has risen very slightly as a proportion of all resources, while construction and industrial mineral extraction has grown much more rapidly. This reflects growth in GDP, which is much faster than population growth, in turn reflecting improved standards of living, growth in urban housing/infrastructure and growth in the consumer society. Fertilizer minerals in particular are essential resources for production of the food needed by an increasing global population. Nitrogen fertilizer manufacture requires fossil fuels-especially natural gas (methane) as a source of the hydrogen needed for the HaberBosch process. Phosphate fertilizers are predominantly manufactured using phosphate rock as a source of phosphoric acid, and there is scope to recover phosphorus from contaminated waters. Potassium fertilizers are produced from evaporite deposits, mainly in the global north. It is difficult for poorer countries with deeply leached soils to access and make efficient use of existing conventional products. Globally, while N and P fertilizer application replaces the nutrient removed by crops and so is in balance, twice as much K is being removed from soils as is being replaced. This leads to the need for innovation in developing novel sources of K, especially to support agricultural production in the global south. Rocks containing K silicate minerals (such as feldspar and nepheline) occur widely as potential sources of K for use in soils where these minerals weather rapidly. Observations of surface corrosion in feldspars taken from soils after 10 years exposure to soil microbial systems demonstrates rates of dissolution 4 orders of magnitude greater than determined in the laboratory. Innovation in use of these minerals depends on an understanding of the role of microbial processes in silicate mineral decomposition.
