“…Agricultural management can affect soil organic matter chemistry and microbial community structure, but the relationship between the two is not well understood [36]. The origin and mineralization processes of soil organic P are less well understood [37]. Fungi tend to contain a significant proportion of their total P content in inorganic forms, i.e., as orthophosphate or as polyphosphates.…”

“…Fungi tend to contain a significant proportion of their total P content in inorganic forms, i.e., as orthophosphate or as polyphosphates. However, based on the results by Makarov et al [37], differences in the microbial community composition may also influence the chemical composition of organic P in soil. Differences in archaeal, bacterial and fungal community structures were observed in the March 2008 and January 2009 samples.…”

Abstract:The processes of land conversion and agricultural intensification are a significant cause of biodiversity loss, with consequent negative effects both on the environment and the sustainability of food production. The anthrosols associated with pre-Colombian settlements in the Amazonian region are examples of how anthropogenic activities may sustain the native populations against harsh tropical environments for human establishment, even without a previous intentionality of anthropic soil formation. In a case study (Model I-"Slash-andBurn") the community structures detected by automated ribosomal intergenic spacer analysis (ARISA) revealed that soil archaeal, bacterial and fungal communities are heterogeneous and each capable of responding differently to environmental characteristics. ARISA data evidenced considerable difference in structure existing between microbial communities in forest and agricultural soils. In a second study (Model II-"Anthropogenic Soil"), the bacterial community structures revealed by terminal restriction fragment length polymorphism (T-RFLP) differed among an Amazonian Dark Earth (ADE), black carbon (BC) and its adjacent non-anthropogenic oxisoil. The bacterial 16S rRNA gene (OTU) richness estimated by pyrosequencing was higher in ADE than BC. The most abundant bacterial phyla in ADE soils and BC were Proteobacteria-24% ADE, 15% BC; Acidobacteria-10% ADE, 21% BC; Actinobacteria-7% ADE, 12% BC; Verrucomicrobia, 8% ADE; 9% BC; Firmicutes-3% ADE, 8% BC. Overall, unclassified bacteria corresponded to 36% ADE, and 26% BC. Regardless of current land uses, our data suggest OPEN ACCESSDiversity 2010, 2 788 that soil microbial community structures may be strongly influenced by the historical soil management and that anthrosols in Amazonia, of anthropogenic origins, in addition to their capacity of enhancing crop yields, may also improve microbial diversity, with the support of the black carbon, which may sustain a particular and unique habitat for the microbes.

“…Pyrophosphate is ubiquitous in soils, where it appears to originate mainly from soil fungi (Rasmussen et al, 2000;Makarov et al, 2005;Bünemann et al, 2008). However, the role of pyrophosphate in the nutrition of plants remains poorly understood, due in part to the difficulty in its quantification at low concentrations in soil solution.…”

“…The strong correlations between pyrophosphate in soil solution, native enzyme activity, and microbial phosphorus suggest that soil solution pyrophosphate has a microbial origin. Indeed, several studies have reported high concentrations of pyro-and polyphosphate in soil fungal tissue (Makarov et al, 2005;Bünemann et al, 2008;Koukol et al, 2008). However, the absence of a correlation between soil solution pyrophosphate and pyrophosphate determined by 31 P NMR spectroscopy suggests that these pools are decoupled, perhaps because 31 P NMR spectroscopy detects a relatively stable pyrophosphate pool that is sorbed strongly to the mineral soil matrix (Gunary, 1966) or contained within live fungal tissue (Koukol et al, 2008;Cheesman et al, 2012).…”

“…The other inorganic P species detected was pyrophosphate between −3.5 and −3.8 ppm, identified in all samples except JN-05 (Figure 2). The organic orthophosphate monoesters showed resonances from 3.8 to 5.2 ppm (Figure 1, inset) and the only diester P compound was detected in sample JN-05 (Figure 2) at −1.15 ppm at a very low resonance intensity and was attributed to nonhydrolyzed DNA [31,32]. Phytate (Myo-Inositol hexakisphosphate) was identified at 5.2, 4.4, 4.0, and 3.8 ppm (Figure 1, inset peak A) with the signals occurring in a ratio of 1 : 2 : 2 : 1, corresponding to the phosphate ion group on the inositol ring confirming the phytate peak [31].…”

The release of nutrients, including phosphorus from agricultural residues, is an important potential source of nutrients for subsequent crops. To fully understand the contribution of this residue P as a source of plant P for agricultural production, its chemical nature needs to be understood. In this study P species were identified and quantified in leaf litters and crops residues from cocoa farms, oil palm, rubber, and banana plantations by 31 P nuclear magnetic resonance (NMR) spectroscopy. Phosphorus in the crop residues was predominantly in the form of inorganic P mainly as orthophosphate and ranged from 45.9 to 89.2%. The highest relative percentage of P as orthophosphate was found in cocoa pod husk (89.2%) and the lowest percentage was found in decaying banana pseudostem (45.9%). Pyrophosphate was detected in trace amounts in all samples (less than 6%) except in fresh palm fronds. However, orthophosphate diester was detected only in fresh palm fronds (11.4%) and phytate was detected only in palm male inflorescence (6.7%). The result implied that cocoa pod husk, palm empty fruit bunch, and palm male inflorescence could be used as organic amendment, based on their high P content and release potential.
