Holocene Sediment

The Holocene sediment commonly covers the Mekong River Delta. The most is the fine materials including silt, clay; they are very plentiful. There are a lot of researches about Holocene sediment that study about sediment, formal origin, and pedology, applying for minerals survey and the agricultural development. Aim of this topic to know the characteristics of minerals in the clay and basic geotechnical properties for using the materials to make brick in the Vinhlong province.

The aim of the study was to know a trend of mechanical behavior and geotechnical properties; applied for, calculating the mechanical behavior of the ground, planning the infrastructure, specially the traffic system and port, and building a rational investigated-procedure by combinations of in-situ tests, sampling and laboratory tests. Sedimentary environments of the CLM1 core at Caolanh city, Mekong River Delta (MRD) were reestablished based upon the deposit properties. Investigate the geotechnical properties and origin of the formation of them. CLM1 core site which has seven facies; each facies has presents a typical sequence of the geotechnical properties. Post-depositional processes have important role in formation of geotechnical properties.

Sulfate Soils

The objectives of this study were to isolate and determine the ability of bacterial strains to decompose sugarcane leaves from acid sulfate soils in the Mekong River Delta (MRD). Soil samples were collected from three acid sulfate soils in Ben Luc district, Long An province, Phung Hiep district, Hau Giang province, and Hon Dat district, Kien Giang province where large sugarcane areas cultivated. Six soil samples were collected and coded: LA1, LA2, HG1, HG2, KG1, and KG2. The results of the study have isolated 18 strains of bacteria are capable of producing cellulase enzyme that breaks down cellulose including LA2-4b, LA2-1, LA2-4a, LA2-2, KG2-1, KG2-2a, KG2-2b, KG2-3, KG2-20, KG2-21, KG2-22, KG2-24, KG2-26, KG2-27, LA1-1, LA1-2, LA1-3, LA1-7. All isolated bacterial strains have the ability to effectively decompose sugarcane leaves, have the potential to apply in practical production, and contribute to improving the quality of acid sulfate soils in the MRD. In which, five selected bacterial strains (LA1-1, LA2-4a, LA2-4b, KG2-2b, and KG2-24) were significantly higher (p<0.05) in the decomposition of sugarcane leaves than the treatment without bacteria.
