Basic Characterization (Validity: 5 to 10 years)
Describes the status quo, the current state of the soil and is therefore the basis for the derivation of measures to optimize soil fertility and plant nutrition. With the Initial Sampling, all parameters of the Fractionated Analysis and the dynamic processes in the soil are recorded and evaluated. In a comprehensive report, the analysis results are presented using tables and graphs. Amelioration measures and recommendations are also derived in order to optimize soil fertility and preserve it in a sustainable manner.
If you have any questions regarding the results, you can always contact us! This is a self-evident service for us and of course free of charge!
Among others, you will receive the following information:
- What is the current nutrient supply? Are the nutrients in balance? Can nutrients (e.g. phosphorus) be mobilized or is there a need for fertilization?
- In which acid buffer system is the soil currently located? Is there a need for liming?
- What is the humus content and its quality? What are the environmental conditions for soil organisms?
- Is the soil fit for climate change and soil fertility preserved in a sustainable manner? Is the potential of the site being exploited?
- Are the soil functions (e.g., ground protection, flood protection) fulfilled? Does the soil bear a hazardous potential (e.g., potentially toxic substances)?

Presentation of Results
The results of the analyses are presented in two comprehensive summary sheets (see figures below). Furthermore, a detailed and informative report explains and describes the result.

Summary sheet “Soil Properties“
In the section “Soil Properties“, the basic parameters (water balance, pH-values, electrical conductivity, lime and soil organic matter content/-quality) and the potential and current sorption complex are described and evaluated. Based on that, mineral-organic measures and actions are derived to enhance and/or preserve soil fertility (amelioration measures). The toolbox of measures should be fully implemented within the next 5 to 10 years.

Summary sheet „Plant Nutrition“
In the section “Plant Nutrition“, plant-available substances including the soil reserve pools at the moment of sampling are assessed. The mineralization potential of C, N, P and S is also presented and evaluated.
In this evaluation, the substances are declared in kg/ha, not in mg/kg (taking into account the gravel content). Thereby, a division in content classes is not necessary.
Fertilization recommendations are thus not provided, but instead the differences of the substance quantities (which are required to achieve a certain crop yield for the declared crop) are compared with the actual plant-available substances in the soil at the moment of sampling. The explicit assessment of the reserve fraction enables to predominantly mobilize substances and fertilize only if it is actually necessary. The results of the analysis are therefore a tool with which well-founded statements can be made about the current situation at the time of sampling and can assist in the identification of potential mobilization pathways.
