“…Only trace amounts of orthophosphate monoesters were detected in the NaOH-EDTA extracts from the cattle manure compost, and none were detected in extracts from the compost-amended soils (Figure 2). Organic P is decomposed during the composting processes [45]. The small proportion of organic P in cattle manure compost (10% of total P) was consistent with the reported proportions of organic P in cattle manure compost produced in Japan [45].…”

“…The chemical shift of this peak was assigned to hydroxyapatite, which can be distinguished from CaHPO 4 •2H 2 O (brushite), Ca(H 2 PO 4 ) 2 •H 2 O, and other calcium phosphate minerals [46] (Supplementary Figure S4). One broad peak of cattle manure compost was deconvoluted into two peaks centered at 2.9 and 1.2 ppm, respectively (Figure 3), indicating that hydroxyapatite was added to soil from cattle manure compost [45]. The peak at 1.2 ppm corresponded to that of CaHPO 4 •2H 2 O (Supplementary Figure S4) suggesting the presence of soluble calcium phosphate species in the cattle manure compost.…”

“…Organic P is decomposed during the composting processes [45]. The small proportion of organic P in cattle manure compost (10% of total P) was consistent with the reported proportions of organic P in cattle manure compost produced in Japan [45]. Total P concentration was increased by the application of compost (~1650 mg•kg −1 ), compared to the soil without compost applications (i.e., NPK plot, 1353 mg•kg −1 ) and watersoluble P was less than 1% of the total P and larger in the order of NPK, NPK + compost, PK + compost.…”

“…Hydroxyapatite in the soils from NPK + compost and PK + compost plots was likely derived from cattle manure compost. Cattle manure compost was found to contain hydroxyapatite, which is a Ca-phosphate of lower solubility, and CaHPO 4 and struvite (MgNH 4 PO 4 6H 2 O) of higher solubility [45] (Supplementary Figure S3). The accumulation of hydroxyapatite particularly in the PK + compost plot was also enhanced by higher pH and Ca concentration, which is a thermodynamically favorable condition to stabilize P as hydroxyapatite [40], than the other plots (Table 2).…”

Microscale Heterogeneous Distribution and Speciation of Phosphorus in Soils Amended with Mineral Fertilizer and Cattle Manure Compost

Global concerns for the sustainability of agriculture have emphasized the need to reduce the use of mineral fertilizer. Although phosphorus (P) is accumulated in farmland soils due to the long-term application of fertilizer, most soil P is not readily available to plants. The chemical speciation of P in soils, which comprise heterogeneous microenvironments, cannot be evaluated with a high degree of specificity using only macroscopic analyses. In this study, we investigated the distribution and speciation of P accumulated in soils by using both macro- and microscopic techniques including chemical extraction, solution and solid-state 31P NMR, bulk- and micro- P K-edge X-ray absorption near edge structure (XANES), and electron probe microanalysis (EPMA). Soil samples were collected from a field in which cabbage was cultivated under three amendment treatments: i) mineral fertilizer (NPK), ii) mineral fertilizer and compost (NPK + compost), and iii) mineral fertilizer plus compost but without nitrogen fertilizer (PK + compost). Macro-scale analyses suggested that accumulated P was predominantly inorganic P and associated with Al-bearing minerals. The repeated application of compost to the soils increased the proportion of P associated with Ca which accounted for 17% in the NPK + compost plot and 40% in the PK + compost plot. At the microscale, hot spots of P were heterogeneously distributed, and P was associated with Fe and Ca in hot spots of the NPK + compost (pH 6) and PK + compost (pH 7) treated samples, respectively. Our results indicate that application of compost contributed to creating diverse microenvironments hosting P in these soils.

The overuse of phosphate fertilizer results in the accumulation of surplus phosphorus (P) compounds in soil, and this trend is particularly intense in greenhouse farming.We aimed to characterize P compounds in greenhouse soils by comparing their speciation in soil samples collected from greenhouses and an open field. Two soil types with different phosphate sorption abilities, namely, Ultisol and Andisol, were considered. Phosphorus compounds in the soil were characterized by bulk soil analysis via acid extraction; molecular-scale analyses by solid-state 31 P nuclear magnetic resonance and P K-edge X-ray absorption near edge structure and spatially resolved analyses by electron probe microanalyzer and micro-X-ray absorption near edge structure. Spectroscopic results showed that a larger proportion of P compounds associated with inorganic P compounds associated with calcium (Ca-P) was present in the greenhouse soil than in the open-field soil. Some P compounds in the greenhouse Andisol were Ca-P, even though Andisol has a high phosphate sorption ability due to an abundance of aluminum-bearing sorbents. Heterogeneously distributed spots of Calcium phosphate, most likely hydroxyapatite or tricalcium phosphate, were found at the microscale in the greenhouse Ultisol soil grain. In addition to the detection of poorly-soluble Ca-P, a larger proportion of Ca-P was potentially plant available. Spatially resolved analyses showed that organic amendments containing Ca-P were incorporated into the Andisol soil grains. Our study demonstrated that Ca-P with different solubilities can serve as a source of phosphate even in soils of high phosphate sorption ability under greenhouse conditions.
