“…However, both (1 CSS and CPL composts represented 31 and 40% of the total P, respectively. These results were similar to those found by Gagnon et al (2012), however, Sharpley & Moyer (2000) found similar Pi in the first two fractions in CPL (52%), but found a lower percentage of Pi for the HCl fraction (27%). This difference can be attributed to the lower Ca content of the CPL or to the lower composting time (2 months) compared with that used in the present work (5 months).…”

“…The inorganic P forms (Pi) in water or in the bicarbonate extracts are considered easily available to crops; the Pi extracted in NaOH solution is mainly bound to Fe and Al oxides or metal-organic complexes, and thus considered moderately labile; the Pi extracted in HCl is bound mainly to Ca in low-solubility precipitates, such as apatite or octacalcium phosphate, and thus considered as stable P forms (Traoré et al, 1999;Gagnon et al, 2012).…”

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.

“…Composting has been shown to result in more or less the same or slightly lower P plant availability of the composted compared with fresh manure (Gagnon et al, 2012), with fresh manures having an availability in the range of 90-100% of mineral fertiliser P. Similar results have been reported by Preusch et al (2002) for poultry manure and by Jørgensen et al (2010) for the manure solid fraction, where the content of watersoluble inorganic P in the composted manure remained unchanged or decreased slightly compared with that in untreated manure.…”

“…Those correlations indicate positive effects of soil Ca on P and Mg concentrations in forage, and suggest soil Ca negative effects on Ca concentration and Ca:P ratio in forage. These results suggest plants prefer to take up calcium phosphates and many Ca ions were fixed as its availability increased, whereas soils could had have a low potential to fix natural P. This late idea is supported by Gagnon et al (29) finding in the case of alkaline soils.…”

Mineral concentration in forage is an important factor for extensive livestock production. Therefore, a study was performed in order to evaluate the soil mineral contents and their relationships with forage mineral concentrations taking into account three grassland sites located at Zacatecas state, México. Soil organic matter (OM) content and pH as well as soil and forage contents of Ca, P, Mg, Na and K were estimated. Soil OM contents were not different (P>0.05) among sites averaging 2.99 %. Soil pH of site 2 was higher (P0.05) than those of sites 1 and 3. Soil of site 2 had higher P, Ca and Mg concentrations than the minimum contents used as references. Soil contents of Na and K were lower than the reference contents suggesting deficiencies in all three sites. Considering requirements for growing cattle, P, Ca and Na were at insufficient levels in forage from all three sites. Significant correlations (r Pearson) suggest a positive effect of soil P content on forage P and Mg concentrations. Soil P content could affect forage Ca concentration and Ca:P ratio. Other correlations suggest soil Ca negative effects on forage Ca concentration and Ca:P ratio.KEY WORDS: Phosphorus, Calcium, Magnesium, Sodium, Potassium. RESUMENLa concentración de los minerales en el forraje es un factor importante en la ganadería extensiva. Por consiguiente, un estudio se realizó para evaluar los contenidos de minerales en el suelo y sus relaciones con las concentraciones de los minerales en el forraje, al involucrar tres sitios de pastizales en el estado de Zacatecas, México. Se estimó el contenido de materia orgánica (MO) y el pH del suelo, así como las concentraciones de Ca, P, Mg, Na y Mg en suelo y forraje. Los contenidos de MO en el suelo no fueron diferentes (P>0.05) entre sitios con un promedio de 2.99 %. El pH del suelo del sitio 2 fue mayor (P0.05) que el pH de los suelos de los sitios 1 y 3. Las concentraciones de P, Ca y Mg en el suelo del sitio 2 fueron mayores que los contenidos de referencia. Los contenidos de Na y K en los suelos de los tres sitios fueron menores que los valores de referencia, lo cual sugiere deficiencias. Al considerar los requerimientos del ganado vacuno en crecimiento, P, Ca y Na estuvieron a niveles de insuficiencia en el forraje de los tres sitios. Correlaciones significativas (r Pearson) sugieren un efecto positivo del P en el suelo sobre P y Mg en el forraje. El P del suelo puede afectar al Ca y a la proporción Ca:P del forraje. Otras correlaciones sugieren efectos negativos del Ca en el suelo sobre el Ca y la proporción Ca:P en el forraje.
