2019 PROJECT 8: FFTC 2019 proficiency testing program of soil, plant tissue and fertilizer analysis

2019 PROJECT 8: FFTC 2019 proficiency testing program of soil, plant tissue and fertilizer analysis

Prof. Dar-Yuan Lee, Associate Dean of Bioresources and Agriculture of NTU and Prof Huu-Sheng Lur, Dean, College of Biorsesources and Agriculture of NTU talk to a conference participant at the 14th International Conference of the East and Southeast Asia Federation of Soil Science Societies, where FFTC had a poster exhibit of its 2019 PT program of soil, plant tissue and fertilizer analysis. 

Venue: Samples are prepared in Taiwan
Date: 2019
Participating countries: 47 testing laboratories from 8 countries (Indonesia, Japan, Korea, Malaysia, Philippines, Thailand, Vietnam and Taiwan) 
Co-organizers: Taiwan Agricultural Research Institute (TARI)

The Proficiency Testing (PT) program was jointly organized by FFTC and TARI basically to upgrade inter-laboratory comparisons, which is an essential requirement for calibration of laboratories seeking for certification and accreditation for analytic quality laboratories. Two years ago on September 12-14, an international workshop was organized by FFTC and TARI on “Soil and Plant Tissue Testing Analysis: Testing Methods, QA/QC, Data Interpretation and Application” in Taichung, Taiwan. One of the recommendations of the participants in the workshop was for FFTC to regularly conduct a capacity comparison to help more laboratories in their analysis.

This year, FFTC and TARI continued the proficiency test of soil and plant tissue analysis and increase their fertilizer samples. From the original 25 participants in 2018, a total of 47 laboratories from 8 countries (Indonesia, Japan, Korea, Malaysia, Philippines, Thailand, Vietnam and  Taiwan) participated in the project.

On November 3-4, 2019, the result of two years comparison (2018 and 2019) of PT programs was presented in the 14th International Conference of East and Southeast Federation of Soil Science Societies (ESAFS).

Major findings and recommendations

1. Provided more accurate analysis and reference value when the results of the 2018 PT program were compared to 2019. The number of laboratories participating this year has also doubled, from 25 to 47 laboratories.

2. Improved capability analysis in a significant manner and all the tests were passed by the participating laboratory representatives. Some of the laboratories participating last year adjusted themselves according to the test results (for example, the laboratory in Vietnam).

3. Study and make the necessary improvements as some Southeast Asia Laboraotries’ capabilities in the analysis of trace elements still need to be improved, according to the evaluation results of the PT program.

FFTC’s Assistant Researcher Ms. Jennifer Lii who is also the coordinator of the project on the Proficiency Testing program of soil, plant tissue and fertilizer analysis helps promote the activity through a poster exhibit during the 14th International Conference of the East and Southeast Asia Federation of Soil Science Societies held on November 3-8, 2019 at the Natinal Taiwan University.

Conference delegates read the FFTC poster exhibit of the “2019 Proficiency Testing Program of Soil, Plant Tissue and Fertilizer Analysis.” The Proficiency Testing program is jointly organized by FFTC and TARI to basically upgrade inter-laboratory comparisons, which is an essential requirement for calibration of laboratories seeking for certification and accreditation for analytic quality laboratories.
