Central Vietnam is composed of two contrasting topographic areas parallel to the coastline: mountains in the West and lowlands in the East where most of the population is concentrated. Sandy soils are largely dominant in the cultivated area in this narrow strip along the sea. Typical constraints of these soils are chemical infertility and acidity, excessive drainage capacity, low organic matter content, associated with particular climate limitations: heavy rain, floods and droughts during certain periods. In the paper, we described a detailed survey among 145 households in villages from the 4 districts of the coastal area of the Thua Thien Hue Province. Existing practices and the socio-economic situation are evaluated and selected pilot farmers are involved in the research of optimal practices. Soil samples (300) and organic matter samples (95) are collected during this survey. The partners of the research include the Hue University of Agriculture and Forestry, the National Institute for Soils and Fertilizers in Vietnam, the Faculty of Agricultural Sciences of Gembloux, and the Catholic University of Louvain in Belgium.
