  • Study of the components, and the physical, chemical and physiochemical properties of soils:
  • Soil texture analysis (wet sieve and dry sieve analysis).
  • Determination of the amount of active carbonates and lime in soils.
  • Determination of soil organic matter.
  • Calculation of the soil’s active and reserve acidity.
  • Electrical conductivity and salinity.
  • Base Saturation and Estimated Cation Exchange Capacity.
  • Nitrate nitrogen.
  • Determination of phosphorus and potassium readily available for uptake.
  • Determination of the C/N ratio.
  • Determination of soil water retention (pF-curve/soil moisture %).
  • Calculation of soil moisture content.
  • Determination of available water.
  • Soil density.
  • Determiantion of mineral concentrations.
  • Chemical properties of soils.
  • Optical and electron microscope (transmission, scanning and microanalysis) analysis of soil components.
  • Soil assessment, management and contamination studies:
  • Field sampling for soil profiling.

Policies and Procedures

Both current UCA legal regulations and Regional/State law will be applied in all the stages of services provision. A quotation will be issued upon the request for any of the services offered.

The quotation approval entails the commitment to the provision of the requested service and the corresponding reporting based on the information obtained and/or the analyses performed.


Rates for analysis, data processing and report issuing are established taking into account staff hours, and use of laboratory consumables.

€ 83/staff hour
