Soil and Fertilizer Analysis Laboratory, (SOFREL-TR is an infrastructure of Department of Soil Science and Plant Nutrition, Faculty of Agriculture, Ankara University which has been accredited in five analysis including pH, electrical conductivity, organic matter and lime in soil and   also water-soluble phosphorus in chemical fertilizers, by Turkish Accreditation Agency according to the standard, TS EN7ISO/IEC 17025 under the code of  AB-1300T, on August 17, 2018.

In addition, SOFREL-TR conducts some other analysis such as fractional analysis, soil porosity, mineral (elemental) content in soil, as well as pH, electrical conductivity and elemental content in organic and chemical fertilizers and elemental content in the plant, with no accreditation.

Upon the request, the results of the analysis mentioned above are interpreted and reported in detail by the academic staff of the Department of Soil Science and Plant Nutrition. Our laboratory is authorized by the Ministry of Food, Agriculture, and Livestock, Turkey in the analysis of organic/organomineral fertilizers, soil conditioners, and other enzymatic and microbial products.

SOFREL-TR is a member of the Global Soil Laboratory Network (GLOSOLAN).
