Terraced rice field are located ingreen-tuff areas which are very fertile but where landslides occur associated to strong earthquakes. The Xraydiffraction and X-ray fluorescence analyses of the soils in landslide area identified predominant smectiteand Mg, Al, Si, K, Ti, Mn and Fe are main components. The rice leaf showed that S, Cl, K and Ca playimportant roles for nutrients in the area. Drainpipe systems have set up in the green- tuff areas to reduce therisks of landslides. Reddish brown microbial mats inhabited bacteria and diatom in the drainpipe outlets.The microbial mats are rich in Fe and PO3− 4 . The iron bacteria in the ground water have a high metabolicrate suggesting that the weathering materials were produced by not only physical and chemical influence butalso by microorganism. Many microorganisms attach to mineral surfaces and show their high impact in thewater mineral chemistry in the landslide area. Bacteria in the green-tuff over landslide area play importantroles for sustainable agriculture including rice nutrition. 2006 artículo científico 0001-3765 https://www.redalyc.org/articulo.oa?id=32778410 en http://www.redalyc.org/revista.oa?id=327 Anais da Academia Brasileira de Ciências application/pdf Academia Brasileira de Ciências Anais da Academia Brasileira de Ciências (Brasil) Num.4 Vol.78 |
