Analytical laboratory of the Department of Soil Science

The Analytical laboratory of the Department of Soil Science conducts analyses of physical and basic chemical soil/sediment properties. It is authorized by the Ministry of Agriculture to test soil fertility for agricultural land (in accordance with NN 47/19). The Laboratory periodically performs procedures of internal quality control and, once a year, external quality control through the International Soil-analytical Exchange Programme ISE (WEPAL proficiency test). The Laboratory work includes education, research, and expert activities in the fields of agriculture and wider environmental sciences. The main room of the Laboratory is located on the 2nd floor in the Pavilion no. VI (central building of the Faculty). Rooms for detailed physical soil analyses (soil water permeability and water retention, soil plasticity, etc.) are situated in the basement of the same pavilion.

Soil/Sediment Analyses

  • Preparation of samples for physicochemical analyses (drying, grinding, sieving, homogenizing)
  • Particle size distribution (soil texture)
  • Dry matter and water contents based on the sample mass
  • Volume content of soil water (determined from a sampling core)
  • Stability of soil aggregates
  • Bulk density and particle density
  • Soil water holding capacity
  • Total porosity and air capacity
  • Soil plasticity (liquid limit, plastic limit, plasticity index)
  • Soil water retention in the 0-15 bar range (sandbox and pressure extractors)
  • Hydraulic conductivity of saturated porous material by permeameter (soil permeability for water)
  • Soil water capillary rise
  • Soil organic matter (humus) content, humus character and composition
  • Total carbonate content
  • Physiologically active lime content
  • pH and EC
  • Soil adsorption complex and base saturation
  • Hydrolytic acidity and substitution acidity
  • Mineral nitrogen content (NO3 and NH4) in field-moist soil
  • Total nitrogen content *
  • Plant-available phosphorus and potassium contents (P2O5 and K2O *)

* In cooperation with other departments of the Faculty
