Certified soil science laboratory

The Soil Analysis Laboratory was established in 1975, as an integral part of the Soil and Habitat Laboratory of the Branch in Poznań. Since then, it has been involved in soil and habitat work in the State Forests, nature reserves, and national parks, as well as in the monitoring of dusts fallout, fertilization of tree stands, plantations, and forest nurseries.
In 2008, the Quality Management System according to ISO 9001:2008 standard was implemented, and since 2017 the Laboratory has been operating in accordance with ISO 9001:2015 standard. The scope of this system includes the analysis of the physical and chemical properties of soils. Every year, an audit is carried out by the certification body TUV Rheinland Polska based in Warsaw, which confirms compliance with the requirements of ISO 9001: 2015.

The scope of analyses performed by the laboratory is as follows:

• granulometric analysis of soil according to the modified Prószyński method (areometric and sieve);
• soil pH analysis (pH in H2O and KCl) by potentiometric method; determination of CaCO3 carbonate content by Scheibler’s method;
• determination of organic carbon content Corg by Tiurin method;
• determination of the total nitrogen content Nog by Kjeldahl method;
• determination of the content of exchangeable cations (Ca2+, Mg2+, Na+, K+) by FAAS (flame spectrophotometry);
• determination of hydrolytic acidity Hh by Kappen method (titration); determination of magnesium MgO by Schatschabel method;
• determination of calcium CaO content by Gedroyć method;
• determination of phosphorus P2O5 and potassium K2O by Egner-Riehm method;
• determination of bulk density.

We also perform analyses of soil samples along with fertilization expertise for forest nurseries.
The expert opinions shall include:

• results of laboratory analyses:
  • soil pH: pH in KCl by potentiometric method;
  • components easily absorbed in the soil: P2O5, K2O according to Egner-Riehm method, MgO according to Schachtschabel method;
  • oxidizable organic carbon Corg, according to the modified Tiurin method;
  • total nitrogen Nog, according to the modified Kieldahl method;
• recommended levels of fertilizing doses: N, P, K, Mg, soil, foliar, as well as organic;
• recommendations for regulating soil acidity, liming, or sulfurizing.

The deadline for the expert opinion is approx. one month from the date the samples were delivered to the laboratory.
It is also possible to perform only analyses, without expert reports.

The Soil Analysis Laboratory provides a high standard of services through:

• employing highly qualified employees necessary to perform chemical analyses;
• using documented and validated research methods;
• using efficient and calibrated technical and measuring equipment;
• carrying out checks on the results in independent laboratories making soil analyses in accordance with established research methods.

Customers value our laboratory for:

• timeliness of performed analyses;
• high professional qualifications of employees;
• ease of contact and substantive discussions;
• friendly and competent service.
