“…However, nano‐ or micro‐sized P‐fertilizers provide large specific surface areas that promote their possible attachment to solid soil surfaces . The results of the present incubation‐leaching study are also consistent with those from Ma and Matsunaka who examined three size fractions (<1, 1–2, and 2–4 mm) of biochar (pyrolyzed meat and bone meal from dairy cattle) in a pot experiment. The <1 mm size‐fraction of biochars was most effective to increase P‐dissolution and subsequently promote plant growth.…”

The benefits of bone char (BC) application may include both the mobilization of P for plant nutrition and immobilization of contaminant Cd in the soil. However, previous studies were conducted under equilibrium conditions that do not adequately reflect field conditions. Therefore, the objective was to study the effect of BC, surface-modified BC (BC plus ) and sulfur-enriched activated char (AC S ) application at different particle sizes on P-and Cd-mobilization under non-equilibrium conditions in a combined incubation-leaching experiment. Two soils each with the treatments (i) BC, (ii) BC plus , (iii) BC þ AC S , (iv) control (0 mg P kg À1 soil), and (v) AC S were leached five times during 70 days incubation. Over the complete incubation P-contents in leachates were significantly increased by BC and BC plus of 0.5-1 mm size. P-release from BCs was larger under non-equilibrium condition in this experiment compared with a previous continuous incubation experiment. AC s application reduced the P-release from BC of all particle sizes. The lowest leachate Cd-concentrations were found in soils amended with the smallest BC particles. Addition of BC plus and AC S significantly increased Cd leaching and the highest amounts of Cd were leached at the smallest particle size. In conclusion, the 0.5-1 mm size class of BCs performed best and should be introduced in practical agriculture using standard machinery.

“…This is consistent with the study of according to which the BC application (< 90 µm BC thoroughly mixed in soil) significantly increased the insoluble P proportion (H 2 SO 4 -P). Additionally, our study confirmed previous findings concerning the effect of particle sizes on the P release from BCs (Morshedizad and Leinweber, 2017) and consequently the P status of treated soils (Ma and Matsunaka, 2013). Sequentially extracted P contents increased with the decreasing size of BC particles whereby BC plus treatments appeared more dependent on particle size than BC treatments.…”

Abstract. The acceptability of novel bone char fertilizers depends on their P release, but reactions at bone char surfaces and impacts on soil P speciation are insufficiently known. By using sequential fractionation and synchrotron-based X-ray absorption near-edge structure (XANES) spectroscopy we investigated whether and how the chemical composition of bone char particles has been altered in soil and has consequently affected the P speciation of amended soils. Therefore, two different kinds of bone char particles (BC produced by the pyrolysis of degreased animal bone chips at 800 • C and BC plus , a BC enriched with reduced sulfur compounds) were manually separated from the soil at the end of two different experiments: incubation leaching and ryegrass cultivation. Sequential P fractionation of amended soils showed P enrichment in all fractions compared to the control. The most P increase between all treatments significantly occurred in the NaOH-P and resin-P fractions in response to BC plus application in both incubation-leaching and ryegrass cultivation experiments. This increase in the readily available P fraction in BC plus -treated soils was confirmed by linear combination fitting (LCF) analysis on P K-edge XANES spectra of BC particles and amended soils. The proportion of Ca hydroxyapatite decreased, whereas the proportion of CaHPO 4 increased in BC plus particles after amended soils had been incubated and leached and cropped by ryegrass. Based on P XANES speciation as determined by LCF analysis, the proportion of inorganic Ca(H 2 PO 4 ) 2 increased in amended soils after BC plus application. These results indicate that soil amendment with BC plus particles leads to elevated P concentration and maintains more soluble P species than BC particles even after 230 days of ryegrass cultivation.

By sequential fractionation and synchrotron-based X-ray absorption near edge structure (XANES) spectroscopy we investigated whether and how the chemical composition of bone char particles has been altered in soil and, consequently, has affected the P speciation of amended soils. Therefore, two different kinds of bone char particles (BC, produced by pyrolysis of degreased animal bone chips at 800 ºC and BCplus, a BC enriched with reduced sulfur compounds) were manually separated from the soil at the end of two different experiments: incubation-leaching and ryegrass cultivation. Sequential P-fractionation of amended soils showed P-enrichment in all fractions as compared to the control. The most P increase between all treatments significantly occurred in the NaOH-P and resin-P fractions in response to BCplus application in both, incubation-leaching and ryegrass cultivation experiments. This increase of the readily available P fraction in BCplus treated soils was confirmed by linear combination fitting (LCF) analysis on P K-edge XANES spectra of BCs particles and amended soils. The proportion of Ca-hydroxyapatite decreased, whereas the proportion of CaHPO4 increased in BCplus particles after amended soils had been incubated and leached and cropped by ryegrass. Based on P-XANES speciation as determined by LCF analysis, the proportion of inorganic Ca(H2PO4)2 increased in amended soils after BCplus application. These results indicated that soil amendment with BCplus particles leads to elevated P concentration and maintains more soluble P species than BC particles even after 230-days of ryegrass cultivation.
