This paper presents the results of soil characteristics study and orientation for rational and sustainable use of major soil types in Thai Thuy District, Thai Binh Province, where is facing many environmental problems. The interactive process between river, sea and human activities over time has resulted in the characteristics of 10 soil types, which are grouped in 4 main classes (acid sulfate soil, saline soil, alluvial soil and sandy soil). They have been used for agricultural production (mainly for rice and other crops growing). Initial analysis of soil environment quality has shown that soil environment has been polluted due. | VNU Journal of Science Earth Sciences 23 2007 105-109 An analysis of soil characteristics for agricultural land use orientation in Thai Thuy District Thai Binh Province Pham Quang Tuan College of Science VNU Received 03 March 2007 Abstract. This paper presents the results of soil characteristics study and orientation for rational and sustainable use of major soil types in Thai Thuy District Thai Binh Province where is facing many environmental problems. The interactive process between river sea and human activities over time has resulted in the characteristics of 10 soil types which are grouped in 4 main classes acid sulfate soil saline soil alluvial soil and sandy soil . They have been used for agricultural production mainly for rice and other crops growing . Initial analysis of soil environment quality has shown that soil environment has been polluted due to residual content of pesticides such as Padan and Fen kept in agricultural land. On basis of the analysis of characteristics and environment of the main soil classes the paper has made some recommendations to ensure their sustainable use. Keywords Soil characteristics Sustainable agricultural land use Thai Thuy District. 1. Introduction Thai Thuy is a rural district situated in Thai Binh Province s coastal zone where there is diversification in natural conditions natural resources and land use orientation due to the interactions between marine-mainland factor and human activities. The total area Thai Thuy district is km2 including tidal flat area agricultural land accounts for 64 and 87 of which or 56 of the total area is for paddy rice and other vegetation. It means that agriculture especially paddy and vegetation crops is the major economic activity in the district. Land resources play an important role for Tel. 84-4-8581420. E-mail geography@ agricultural economy. Therefore the rational use of land resources is necessary in order to aim at the sustainable development purpose in the process
