The proper soil sampling is of particular importance in the analytical process, since the respective measures for improving or preserving soil fertility are derived on the basis of the analyzed soil samples. Only a representative sample can provide sound analytical results! Sampling should therefore be well prepared and carried out as follows:

The Proper Timing of Soil Sampling
For acute questions or problems, soil samples can be taken at any moment. However, to systemically assess soil fertility, the soil should be sampled in a state of dynamic equilibrium (steady state). Dynamic equilibrium is established 6 to 8 weeks after the application of management measures (e.g. tillage, input of mineral/organic substances). Favourable moments for soil sampling are often before or after harvesting (before stubble breaking) and in spring (at least 6°C soil temperature for approx. 2 weeks). The soil must not be too soggy, the moisture level should allow passage of the ground. For the resampling, a similar timing should be chosen with regard to the environmental conditions (soil temperature, soil moisture etc.).
Temporary Storage of Soil Samples
If it is not possible to ship the sample immediately, the sample should be stored as follows:
- Unsealed sample stored in a dust-free, dry room at room temperature (storage up to 1 month). Caution: pets and rodents may cause contamination of the sample.
- Sample sealed in the freezer (storage up to 3 months)
Shipment of the Sample
Close the sample carefully and ship it along with the assignment form to the delivery address below. Shipping should not exceed 2 to 3 days. You’re also kindly welcomed to deliver the samples in person.

The results are usually available no later than 3 weeks after receipt of the soil sample in the laboratory of TB Unterfrauner GmbH.
