| 内容記述 | For the evaluation of repressing effect of humates and nitrohumates on phosphorus fixation in upland soils, this study was carried out. Calcium phosphate monobasic was fertilized to Higashiiwanaga redish soil, Aso volcanic-ash soil and Shuhodo white soil treated with sodium, ammonium, iron, aluminium, calcium or magnecium humates and nitrohumates, then moistened prior to drying. Unfixed phosphorus in such soil samples were fractionated in three forms that they were soluble, Truog soluble and 0.2N HCl soluble forms, and each of them was determined. Most of humates and nitrohumates increased remaining of unfixed phosphorus in all soils; water soluble, Truog soluble and 0.2N HCl soluble phosphorus were increased in Aso, water soluble in Higashiiwanaga and Truog soluble in Shuhodo. But remaining ratio of each soluble forms in treated soil was not same to control soil, and the features or capacities of repression by humates and nitrohumates on phosphorus fixation were varied with the kind of humates or nitrohumates, the soils and the difference in humic anions (humic or nitrohumic salt). From these results, it was apparent that the humates and nitrohumates are having the repressing effect against to the phosphorus fixing action of upland soils and reserving available forms of fertilized phosphorus, while it was made plain that the repressing efficiency was estimated from the phosphorus absorption coefficient (reported in previous paper) reflected on this result. | |||||||||||
