Brochure: “Healthy food comes from a healthy soil. An introduction to soil for chefs, sommeliers and gourmets.” (2023)
On 19 June 2023, more than 100 personalities from high-class gastronomy, winemakers and agriculture gathered to marvel and discover soil together at the beautiful “Grand Garten”. Together with Hans Unterfrauner and his team, soil was experienced with all their senses and participants learnt how to conduct simple field assessments.
Do-it-yourself soil testing (2023)
Simple field tests can be used to determine soil parameters for a rapid assessment of a site. It can already be determined in the field whether certain problems exist (e.g. aggregate stability, acidification etc.)
Conversion factors (2022)
Conversion factors of selected nutrients / chemical compounds

Checklist: Is my soil fit for climate change? (2020)
A detailed explanation of the checklist can be found at the ÖKL webinar “Der Boden im Wandel – Neue Voraussetzungen für unsere Landwirtschaft” with DI Hans Unterfrauner, held on 21 December 2020.

Visual summary of the topics „Soil sampling”, „Nutrients“, „Phosphorus” and „Buffering systems”.
Nutrients
It all depends on the right ratio!
Complex interaction, Ca, Mg, K, N, P, S, B, Mo, Fe, Mn, Zn, Cu
Soil sampling
The basis of reliable analysis results!
Motivation, preparation, implementation, analytics.
Buffering systems
…more than just a pH value!
Acidification, soil pH in water and in neutral salt, buffering systems, availability of nutrients, amelioration.
Phosphorus
Analysis and mobilization instead of fertilization!
Phosphorus: pools, mobilization, dynamic, conversion factors.
Information sheets for Analytics
Water-soluble elements
The water-soluble elements of a soil determine the element concentrations in the soil solution, the most important medium for plant nutrition …
Exchangeable elements
Organic and mineral particles have loaded surfaces and attach so-called cations. Under certain conditions these cations can be suppressed (= exchanged) …
Plant-available elements
Plant-available elements are accessible to plants during the vegetation period…
Reserve fraction/mobilizable elements
The reserve fraction includes elements which become plant-available through weathering processes within 10 to 15 years…
Phosphorus in the soil
Studies as well as our own research show that most of the agricultural used soils possess enormous reserves of phosphorus. These reserves can be mobilized using different strategies…
Information sheets for Analytical Programs
Initial Sampling / Basic Characterization
The Basic Characterization records and evaluates the nutrient balance and dynamic processes in the soil. This analytical programme is recommended for characterising the status quo of soil fertility. From the analytical results obtained, measures and recommendations are derived to optimise and sustainably secure soil fertility. In addition, changes in farming practices, fertiliser strategies, etc. can be evaluated.
Resampling
Resampling is only possible after Initial Sampling (Basic Characterization) and serves to monitor the changes induced by the implemented melioration. Two analytical programs are being offered.
Resampling A – Comparison of Soil Properties & Plant Nutrition – includes the same basic parameters and fractions (elements in the water extract, in the exchange extract and in the reserve fraction) as the Basic Characterization, the results are presented by means of a comparative short report.
Resampling B – Comparison of Soil Properties – includes the same basic parameters as the Basic Characterization (without fractions), the results are presented comparatively using the summary sheet “Soil Properties”.
Soil expertise and assessment
A professional soil assessment examines, among others, the suitability of land and agricultural areas for the intended land use. Physical and chemical parameters are evaluated, and a site is assessed with regard to its soil functions…
