“…This study utilised a management-induced gradient in lime addition and hence pH, and found accumulation of some specific organic P species only occurred under extremely acidic conditions of pH < 4. Similarly, Annaheim et al (2015) reported that 62 years of application of three organic fertilisers (dairy manure, compost and dried sewage sludge) had no discernible effect on organic P speciation, despite substantially increasing both extractable and total P, in some cases by a factor of two or more. In another study, 100 years of superphosphate addition to a pasture soil had virtually no impact on organic P speciation, despite having profound effects on many soil properties, including total and extractable P and pH, and also pasture composition (Schefe et al 2015).…”

Abstract. Few studies have considered the influence of climate on organic phosphorus (P) speciation in soils. We used sodium hydroxide-ethylenediaminetetra-acetic acid (NaOH-EDTA) soil extractions and solution 31 P nuclear magnetic resonance spectroscopy to investigate the soil P composition of five alpine and sub-alpine soils. The aim was to compare the P speciation of this set of soils with those of soils typically reported in the literature from other cold and wet locations, as well as those of other Australian soils from warmer and drier environments. For all alpine and sub-alpine soils, the majority of P detected was in an organic form (54-66% of total NaOH-EDTA extractable P). Phosphomonoesters comprised the largest pool of extractable organic P (83-100%) with prominent peaks assigned to myo-and scyllo-inositol hexakisphosphate (IP 6 ), although trace amounts of the neo-and D-chiro-IP 6 stereoisomers were also present. Phosphonates were identified in the soils from the coldest and wettest locations; a-and b-glycerophosphate and mononucleotides were minor components of organic P in all soils. The composition of organic P in these soils contrasts with that reported previously for Australian soils from warm, dry environments where inositol phosphate (IP 6 ) peaks were less dominant or absent and humic-P and a-and b-glycerophosphate were proportionally larger components of organic P. Instead, the soil organic P composition exhibited similarities to soils from other cold, wet environments. This provides preliminary evidence that climate is a key driver in the variation of organic P speciation in soils.

“…In this sense, this method has allowed to establish that temperate soils with intensive management of grasslands have similar proportion of inorganic orthophosphate and monoester P concentrations (Stutter et al, 2015), and the long-term addition of organic Journal of Soil Science and Plant Nutrition, 2016, 16 (2), 490-506 fertilizers has little effect on soil P o (Annaheim et al, 2015). Furthermore, in Chilean volcanic soils, it is reported a greater proportion of monoester P under a lupin-wheat cropping system compared to oat-wheat (Redel et al, 2011), andBriceño et al (2004) reported a wide range of monoester P and orthophosphate concentrations for diverse natural Chilean soil Series.…”

Volcanic ash derived soils represent between 50-60% of the total arable land area of southern of Chile, and they are the most important soils for pasture production. In these soils, high phosphorus (P) fixation and, in turn, low P availability and high aluminium (Al) soluble concentrations (at low pH) are the most limiting factors for pasture production. At the same time, the complexes between Al-or iron-(Fe) and organic matter as well as short-range order alumino-silicates (allophane) allow the retention of huge quantities of soil P. The aim of this work was to assess the status of P by both sequential extraction procedure (Hedley) and 31 P-NMR analysis as influenced by Al and Fe in volcanic grasslands Andisols (Pemehue, Gorbea, Piedras Negras and Llastuco Soil Series) from Southern Chile. We applied Hedley chemical sequential fractionation to soils in order to examine the potential differences in extractable soil inorganic P (P i ) and organic P (P o ) fractions. We also determined total P and Olsen P in these grassland Andisols. Oxalate and pyrophosphate were employed to determine the active and organic matter complexed Al and Fe, respectively. Furthermore, we quantified Al and Fe in extracts of the Hedley P fractions. We found that Al extracted in oxalate was correlated positively with labile P o concentration, specifically with both the NaHCO 3 -P o (r=0.45, P≤0.01), and the NaOH-P o (r=0.43, P≤0.01) fractions. This observation was reinforced by 31 P-NMR analysis that showed higher monoester P and myo-IP 6 content in soils with higher amounts of oxalate Al. Hedley sequential fractionation procedure confirmed the role of Al in the NaOH-P o fraction for promoting P o storage, as both fractions were correlated (r=0.33, P≤0.05). In addition, Fe plays a substantial role in recalcitrant P accumulation as we found a high correlation between residual P and oxalate Fe (r=0.55, P≤0.01).

“…For temperate soils, an examination of soil phosphorus composition under contrasting agricultural management systems in the United Kingdom reveals marked variation in the proportions of inorganic and organic phosphorus and the chemical nature of the soil organic phosphorus (Stutter et al, 2015). However, this does not appear to reflect differences in phosphorus inputs, because in a separate study the long-term additions of organic fertilizers, including dairy manure, compost, and sewage sludge, to Swiss soils did not greatly alter the amounts or chemical nature of soil organic phosphorus compared to conventional mineral fertilizer additions (Annaheim et al, 2015). In the tropics, a study of Colombian pastures reveals that soil degradation reduces organic phosphorus concentrations via a decline in soil organic matter associated with macro-aggregates, demonstrating a link between soil structure and the stabilization of soil organic phosphorus (Nesper et al, 2015).…”
