Hydroxyapatite can immobilize heavy metals in soil and thereby prevent plant uptake. We investigated the effect of hydroxyapatite prepared from cattle bones on copper, zinc, cadmium, and lead in soil and concentrations in komatsuna (Brassica rapa L. var. peruviridis). It greatly decreased the concentrations of exchangeable forms of these metals in the soil and contents in the edible parts of komatsuna. Thus, cattle-derived hydroxyapatite can reduce the availability of heavy metals in soil.

To investigate the decomposition of hot-water-extractable soil organic matter (HWESOM) during aerobic soil incubation, we measured contents of dissolved organic carbon (C) and nitrogen (N) over time. Samples of four soil types with one of two fertilizer treatments were incubated at 30 ℃ for 5 months. The quantity of organic N in the HWESOM corresponded to 47〜65% of the total N mineralized during incubation. During incubation, the organic N content of the HWESOM decreased by 43〜90% and the organic C content decreased by 17〜37% of the initial contents. Assuming that the decomposition involved first-order reactions, the decomposed organic N and C had similar half-lives of several weeks. They were characterized by a low C/N ratio (3.4〜6.0), similar to that of proteins. The hydrolyzable amino acid content of the HWESOM decreased, but the amino acid composition did not change. The molecular weight distribution of the HWESOM was determined by high-performance size-exclusion chromatography with chemiluminescent N detection and VIS 420 nm: the organic N in compounds of large molecular weight (>10000 Da) and absorbance at 420 nm due to humic-acid simultaneously-decreased during incubation. Therefore, the decomposed organic matter consisted of proteins and humic-acid-like moieties.

We analyzed the top 15 cm of soil at 133 sites in a region of Andosols around the northern Aso somma and the east of the Kuju Plateau, Kyushu; we divided the samples into 69 nonallophanic soils (Al_p/Al_o ≥ 0.5), 59 allophanic soils (Al_p/Al_o < 0.5), and 5 non-Andosols. Nonallophanic soils were densely distributed on the Kuju Plateau and on the northwestern Aso somma; their acidity was similar to that of nonallophanic Andosols in other regions, such as Tohoku, whereas the total carbon content, the ratio of total carbon to Al_p/Al_o, and the ratio of total carbon to Al_p were larger than those of other regions. In addition, the relatively large Sio of the nonallophanic soils suggested a greater content of allophane and imogolite than in nonallophanic Andosols in other regions. The nonallophanic and allophanic soils in this area could be distinguished to a large extent by pH(H_2O) and color.
