The work of Central Laboratories is closely connected with the work of other departments of Agricultural Institute of Slovenia. At the Laboratories, independent research and expert projects, expert-advisory work and analyses ordered by customers are carried out. At present there are 26 persons employed of which 11 researchers, 12 technicians, 2 (female) administrators and one quality manager. Central Laboratories are furnished with up-to-date analytical appliances distributed over a surface of 400 m2. They have been accredited by Slovenian Accreditation (SA). Following the nature of their work, Central Laboratories are divided in the following two units:

  • Agrochemical Laboratory and
  • Oenological Laboratory.


AGROCHEMICAL LABORATORY 

The research activity of Agrochemical Laboratory is closely connected in joint research and expert projects with other Departments at the Institute. In frame of the projects new analytical methods are developed taking into account the content of particular projects. The research activity covers the following fields:

  • Analyses of dithiocarbamate residues in potato in order to study the causes of exceeded limit values and optimisation of potato production technology so that, considering the principles of good agricultural practice, the maximum residue levels will not be exceeded in future.
  • Creation of code of good agricultural practice and/or creation of guidelines to prevent the contamination of soil with different contaminants used in agriculture, and guidelines for the use of organic substrates (sewage sludge from waste water treatment plants, composts and slurry) in agricultural land.
  • Development of methods used for the examination of agricultural products and food in accordance with internationally recognised reference methods for the official surveillance of agricultural products and food.
  • Determination of ammonia emissions from agricultural land as a result of various systems of slurry use and measures taken to reduce these emissions.

In frame of its expert work the Agrochemical Laboratory monitors pesticide residues in agricultural products. The data thus collected allow an insight in the state of contamination of agricultural products resulting in timely taking of measures and preparation of expert basis required for the reduction of degree of contamination of agricultural products with pesticide residues.
The results of the monitoring are intended for:

  • Determination of conformity with the prescribed maximum residue levels (MRL),
  • Identification of contaminated agricultural products,
  • Determination of source or cause of contamination,
  • Determination of conformity of production with good agricultural practice.

In co-operation with Agricultural Advisory Service of Ljubljana the content of plant nutrients in soil of the water protected area situated in the area of Town Community of Ljubljana (VVO MOL) is monitored. The purpose of the monitoring is to control the supply situation of soil with plant nutrients and, on the basis of the results of analyses, to give advice upon the use of fertilisers in VVO MOL following the legal restrictions valid for these areas. The monitoring is carried out in the area of Waterworks Jarški Brod, Kleče and Savlje, and Hrastje.

To meet the demands of its customers, Agrochemical Laboratory performs the following analyses:

  • Analyses of animal feeds,
  • Analyses of honey,
  • Analyses of food of plant origin,
  • Analyses of soil and composts,
  • Analyses of mineral, organic-mineral and organic fertilisers,
  • Analyses of plant protection products,
  • Analyses of residues of plant protection products found in agricultural products.


OENOLOGICAL LABORATORY
 

Oenological Laboratory has been authorised to make all the analyses of wine and spirits prescribed for the inland trade, exports and imports. Additionally, methods are developed which are expected to become interesting for the market in future. 

METHODS-WINE 
Determination of relative density at 20°C, concentration of alcohol, total dry extract, reducing sugars, total sulphur dioxide, free sulphur dioxide, pH, total acidity, ash content, volatile acidity, saccharose, phosphates, organic acids, sorbic acid, total polyphenols, total anthocyanins, low molecular and high molecular tannins, profile of anthocyanins, profile of hydroxycinnamates. 

Beside physical-chemical analyses, Oenological Laboratory as an authorised organisation organises commissions in frame of which organoleptic evaluation of wine is performed by wine tasters. 

METHODS-SPIRITS 
Determination of relative density at 20°C, concentration of alcohol, total dry extract, volatile substances and methanol. 

The research activity is directed towards determination of sugar origin by means of isotopic and chemometrical methods, introduction of new technological methods in wine production and research of phenolic substances in wines. 

In frame of expert work, Oenological Laboratory provides studies on the protection of wines originating from Belokranjski and Bizeljsko-sremiški vine growing district. Also, new analytical methods used for determination of hydroxycinnamon acids, polyphenols, anthocyanins and tannins in wine are being introduced.
