Laboratory for soil and agroecology

About

Laboratory for Soil and Agroecology offers basic research, expert services and analyses to all interested parties. Laboratory conducts basic and complex analyses of:

  • soil,
  • pesticides (chromatography),
  • fertilizers,
  • plant material,
  • irrigation water.

Accreditation and licenses

The Laboratory is accredited by the Accreditation Body of Serbia (ATS) according to the standard SRPS ISO/IEC 17025:2017 decision number 01-003. It was the first laboratory to be accredited for soil analyses in the Republic of Serbia in 2001.

Additionally, the Laboratory is licensed by the competent Ministry of Agriculture, Forestry and Water Management of the Republic of Serbia to analyse: physical and chemical properties of soil, harmful and dangerous substances in the soil, elemental composition and physiological properties of plant material, physical and chemical analyses of fertilizers and biological value of fertilizers, chemical analyses of water, physical and chemical properties of pesticides and pesticide residue in soil, water, plant material and foodstuffs.

Institute of Field and Vegetable Crops has complied its processes and work units with the standards ISO 9001:2015 (TÜV SÜD № 12 100 50114 TMS) Quality Management System and ISO 14001:2015 (TÜV SÜD № 12 104 50114 TMS) Environmental Management System.

The most important equipment in the Laboratory:

  1. Gas chromatograph Agilent 6890N with mass detector Agilent 5975B
  2. Gas chromatograph ECD/FID Agilent 7890A
  3. Liquid chromatograph HP 1100
  4. Gas chromatograph HP 5890
  5. Inductively coupled plasma ICP-OES VistaPro Varian
  6. Atomic absorption spectrophotometer SpectrAA-600 with graphite technique GTA100 Varian
  7. CHNS analyser VarioEL III
  8. Mercury Analyzer – Direct DMA 80
  9. Spectrophotometer UV/VIS Cary 60 E Agilent
  10. Microwave digestion system ETHOS1 Milestone
  11. Flame photometer Scherwood M410
  12. Soil column sampler and piezometer installation equipment (Cobra)
  13. Drone (Phantom 4)

The Laboratory is fully equipped for field sampling with 5 off-road vehicles, sampling equipment (a set of ergonomic Eijkelkamp augers for sampling all soil types) and handheld GPS units.

Analytical procedures comply with appropriate SRPS Serbian standards of the Institute for the standardization of Serbia and with contemporary documented methods and methods by international and/or national associations, such as:

  • ISO (International Organization for Standardization),
  • AOAC (Association of Official Analytical Chemists),
  • USEPA Test Methods (US Environmental Protection Agency),
  • CIPAC (Collaborative International Pesticides Analytical Council).

The Laboratory has appropriate analytical standard substances and uses BCR reference materials (European Commission, Joint Research Centre, Institute for Reference Materials and Measurements) to check accuracy and precision.

The Laboratory regularly participates in national and international interlaboratory comparisons and proficiency tests.

Soil analyses and sampling:

  • soil sampling in disturbed and undisturbed condition,
  • creation of pedological maps and studies,
  • creation of information system on the soil,
  • soil testing before planting perennial crops
  • other projects, studies and reports in the field of soil testing,
  • basic soil fertility parameters with recommendations for fertilization,
  • elemental composition of soil: macroelements Ca, Mg, K, Na, Fe; trace elements Cu, Zn, Mn, Co, Mo, B; heavy metals Pb, Cd, Ni, Cr, As, Hg,
  • organic soil pollutants (residues of pesticides and their metabolites, PAHs, PCBs, hydrocarbons),
  • physical properties of the soil.

Fertilizer analyses and sampling (mineral and organic fertilizers)

The Laboratory controls plant nutrition products on behalf of the Internal and Border Phytosanitary Inspection when those are imported and when fertilizers are registered or entered into the Register of Plant Nutrition Products. The Laboratory also controls the quality fertilizers and soil conditioners for individuals and legal entities.

The Laboratory has confirmed the quality and precision of its accredited methods, the expertise of its staff and the choice of modern instrumental techniques by participating in demanding interlaboratory comparisons between many laboratories in the world. Trained samplers will collect samples on site at the request of clients.

The Laboratory is licensed by the Ministry of Agriculture, Forestry and Water Management of the Republic of Serbia to register fertilizers and analyse physical and chemical properties and biological value of fertilizers.

The Laboratory analyses inorganic and organic fertilizers, mixed organic-inorganic fertilizers, soil conditioners (inorganic and organic compost), substrates and other products.

Pesticide analyses and sampling (chromatography)

Quality analyses of plant protection products includes determination of active matter content and assessment of other physical and chemical properties of the formulations.

The Laboratory analyses organochlorine pesticide residue and other organic pollutants present in the soil (PAHs, PCBs, total hydrocarbons, aliphatic and aromatic hydrocarbons), fatty acid composition in the oil, and cannabinoids in hemp.

Plant material analyses

The Laboratory analyses the contents of protein, oil, cellulose and ash. These parameters are important for the final product as well as for plant material intended for feed and silage. ADF, NDF and ADL analyses are especially interesting regarding cellulose digestibility.

The Laboratory analyses fatty acid composition in oil, fatty acid trans-isomers, free fatty acid content in oil and pesticide residues in the plant material (organochlorines, organophosphates, and dithiocarbamates).

Irrigation water analyses and sampling

Installation of direct wells (piezometers) and sampling of underground, seepage and surface water.

Dry residue, EC, pH, contents of CO32-, HCO3-, SO42-, NO3-, chloride content by Mohr method, contents of Ca, Mg, K, Na, sodium adsorption ratio (Na-SAR), contents of trace elements and heavy metals.

Interpretation of the results includes recommendations regarding the quality and suitability of irrigation water.
