| 内容記述 | Eight samples from ejecta deposits from Gallungung Volcano, West Java, Indonesia. were collected. The thick deposits of ejecta caused serious damage to the agriculture around the volcano. In this study, apart from the direct damage, the ejecta (volcanic ash, scoria etc.) was examined with special attention paid to its nutritional status. All the samples were found to contain considerable amounts of available (common extractants soluble) nutrients : i.e. N, P, K, Ca, Mg, Na). Especially, the occurrence of soluble N was noticeable because primary magma contains almost no nitrogen compounds. These nutrients are, of course, effective to crop growth. Most of the samples contain more or less of a secondary crystalline mineral, smectite, which is capable of retaining larger amounts of H_2O and nutrient cations as exchangeable ones. In the tropics, the soils in volcanic zones are thought to be fertile. The fertilities are partially attributable to the fresh ash falls which have the nutritients found here. |
