TRACE ELEMENTS IN TROPICAL ASIAN PADDY SOILS : I. Total Trace Element Status
スポンサーリンク
概要
- 論文の詳細を見る
Four hundred eighty two samples of paddy soils collected in ten Tropical Asian countries were analyzed for total contents of eleven trace elements, i.e. boron, chromium, cobalt, copper, molybdenum, nickel, rubidium, strontium, vanadium, zinc, and zirconium. Results were presented in histograms, showing the distribution patterns of the data, and tables, showing the statistical summaries of the data by countries. In general, it appeared that among the Tropical Asian paddy soils, the Philippine soils contain high amounts of total cobalt, molybdenum, strontium, vanadium, and zinc but low amounts of total rubidium and zirconium. Burmese soils show high amounts of total boron, chromium, copper, molybdenum, nickel, and zinc. Vietnamese soils are rich in total chromium, molybdenum, and rubidium. Cambodian and both East and West Malaysian soils are generally poor in most of the total trace elements studied. Contents of the total trace elements studied in the soils of Sri Lanka, Bangladesh, India, Indonesia, and Thailand are intermediate between the values recorded in the former soils.
