11. 6. Proficiency testing
Has your lab joined a proficiency testing (PT) program?
If ‘yes’, which PT program?
[Proficiency testing (PT) or ‘inter-laboratory comparison’ compares the results
obtained by different laboratories.
Ex) Soil test analysis(1980~present)
∙ arable type: paddy, upland, orchard, plastic film house
∙ Investigation point: Non-fixed point(about 450,000)
∙ Cycle: every year
∙ Data: chemical properties(pH, OM, Av.P, Ex.cation ect.)
∙ Sampling depth: 0-20 cm
∙ Accumulated data: 10,865 thousand(fields: 15 million)
Non-fixed point

12. 7. Accreditation
Does your lab have any accreditation or certification?
Unfortunly ‘No’
But NAS supplys soil information

13. 7. Accreditation
Soil Statistics
For children Fertilizer recommendation
Topography
Crop suitability

14. 8. Data interpretation
If your answer is ‘yes’, please fill the table and indicate
what is considered as low/medium/high by your lab.
Do you provide interpretation of soil results to your clients?
Method Units Rating
Low Moderate High
Carbon Tyurin or CN analyzer (Organic matter, g/kg) 2.0-3.0
Nitrogen
Kjeldahl digester
or CN analyzer (g/kg) N/A
Nitrate-N 2M KCl (mg/kg) N/A
Phosphorus Lancaster (Av. P2 O5 mg/kg) 80-550
Potassium 1N ammonium acetate (cmol(+)/kg) 0.5-0.8

15. 9. Interpretation report for your clients
Soil testing
Data input
Result output
Provide to farmer

16. 10. Soil analysis in your country
How many routine laboratories exist in your
country?
250 of technical center
Are they ‘mobile’ laboratories?
No, but the experts is sampling for soil test analysis.
Are the soil test kits commonly used?
No, but we are used to soil diagnosis by portable
equipment.

17. 11. Strength/weakness
What do you think your lab is strong at?
Soil database and digital mapping
What do you think that could be improved?
Quantitative soil information: DSM
What do you wish to get improved after our meeting ?
Network for national cooperation

18. Thank you for your attention…
