  • Using Soil Information for Agricultural Production in Vietnam

    Research results of the Soils and Fertilizers Research Institute

    Advancing the Science and Technology of Soil Information in Asia - Launch of the Global Soil Partnership’s Asia Soil Science Network and GlobalSoilMap.net

    East Asia Node 8-11 February, 2012, Nanjing, China

    SOILS AND FERTILIZES RESEARCH INSTITUTE (SFRI)

  • Overview of Vietnam

    Population: ~87 million

    Total areas: 33.1 million hectares

    Cultivated land: ~9.6 hectares

    Main export products from agriculture: Rice (>3.2 billion USD), coffee (>1.8), cashew nut (>1.1), pepper (>0.4), rubber (>2.5) and tea (~0.2)

    Agro-ecosystems: 8 parts

    Major soils: Acrisols, Fluvisols, Ferrasols, Gleysols and Arenosols

  • SFRI Introduction

    SFRI is a public science unit belonging to Vietnam Academy of Agricultural Sciences (VAAS), and has functions on scientific researching, technology transferring, producing and trading in the areas of soil, fertilizer and microbiology on the whole Vietnam

    The organization of the Institute: - 3 administrative departments - 5 research departments; and - 4 research centers.

  • Using Soil Information

    1. Land evaluation;

    2. Land use planning;

    3. Fertilizer recommendation;

    4. Web-map; and

    5. Geographic indicator for traditional crops

  • Experiences

    1. Simplify soil information in maps

    2. Link soil information with fertilizer recommendation, cultivation regime…

    3. Use internet as a tool for transferring soil knowledge
