The Department performs laboratory testing of soils, mineral and organic fertilizers, soil improvers, substrates, and plant material. Test results are used to assess agrochemical properties, product quality control, plant nutrition optimization, support for registration procedures, and scientific research.<\/span><\/p>

The work of the Department combines service and consultancy testing, development and application of analytical methods, conducting biological tests and trials, cooperation with industry, as well as supporting the educational and scientific research work of the Faculty. In addition, it participates in the implementation of scientific research projects.<\/span><\/p>

The Department of Agrochemistry is accredited according to the requirements of the SRPS ISO\/IEC 17025:2017 standard, <\/b>by the Accreditation Body of Serbia (ATS) under accreditation number 01-541 dated August 14, 2023.<\/span><\/p>

The Department of Agrochemistry is authorized by the Ministry of Agriculture, Forestry and Water Management <\/b>to perform laboratory and related professional tasks in the field of plant nutrition products and soil improvers as of <\/span>September 19, 2022<\/span>.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
