The International Union of Soil Sciences (IUSS) is the global union of soil scientists. The objectives of the IUSS are to promote all branches of soil science, and to support all soil scientists across the world in the pursuit of their activities. This website provides information for IUSS members and those interested in soil science.

International Training On Soil Examination And Fertility Evaluation

Leyte, Philippines

The International Training on Soil Examination and Fertility Evaluation was held at the Leyte State University (LSU), Baybay, Leyte, Philippines on 16-18 August 2006. Organized by Dr. Victor B. Asio, Professor and Head of the Department of Agronomy and Soil Science at LSU, the training attracted 21 participants composed of teachers and graduate students of soil science, ecology, crop science and forestry from various universities in the Philippines as well as graduate students of forestry and agro-ecology from the Universities of Goettingen and Hohenheim in Germany.

Prof. Dr. Reinhold Jahn, Director of the Institute of Soil Science and Plant Nutrition at Martin Luther University in Halle, Germany, and former Chairman of the IUSS Soil Geography Commission, served as the main resource person of the training. His travel to Leyte was supported by a Visiting Professor Grant from the German Academic Exchange Service (DAAD) in Bonn, Germany. Other lecturers in the training included Dr. Asio, former 2nd Vice-Chair of the IUSS Soil Geography Commission, and Dr. Anabelle B. Tulin, Professor of Soil Chemistry at LSU.

The training consisted of two days of lecture and one day of field work. The topics discussed in the lecture/theoretical part of the training included soils as part of landscapes, physicals and chemical properties of soils, soils of the Philippines and Soil Taxonomy, soils of the tropics, factors of soil fertility and methods of assessing soil fertility, soil description (FAO method), WRB soil classification system and soil evaluation. The training gave emphasis on the newly published Guideline for Soil Description by FAO (2006), the WRB soil classification system and the soil evaluation procedure based on the method of Schlichting, Blume and Stahr. On the third and final day, the participants had the opportunity to do actual soil description and evaluation during the field work in the Natural Park at Lake Danao, a beautiful lake surrounded by forest in the central highlands of Leyte at an elevation of about 700 m asl. The participants enjoyed examining and evaluating Andisols developed from Quaternary volcanics which are widespread in the area.

The training was jointly sponsored by the Department of Agronomy and Soil Science and the Institute of Tropical Ecology of Leyte State University (www.lsu-visca.edu.ph), and the Institute of Soil Science and Plant Nutrition of Martin Luther University, Halle, Germany. It was officially recognized and endorsed by the Commission of Higher Education (CHED) of the Philippines. In response to the request from the participants, a follow-up second training is planned for 2008.
