Grafic Recording “Soil fertility & Climate change” (2019)
Visual transcript of a one-day seminar held by Hans Unterfrauner about soil fertility and climate change, drawn by Robert Six.
Information printed on beer coasters
Visual summary of the topics „Soil sampling”, „Nutrients“, „Phosphorus” and „Buffering systems”.
It all depends on the right ratio!
Complex interaction, Ca, Mg, K, N, P, S, B, Mo, Fe, Mn, Zn, Cu
The basis of reliable analysis results!
Motivation, preparation, implementation, analytics.
…more than just a pH value!
Acidification, soil pH in water and in neutral salt, buffering systems, availability of nutrients, amelioration.
Analysis and mobilization instead of fertilization!
Phosphorus: pools, mobilization, dynamic, conversion factors.
Information sheets for analytics
The water-soluble elements of a soil determine the element concentrations in the soil solution, the most important medium for plant nutrition …
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 growing season …
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 intentionally…
Information sheets for analytical programs
Is it necessary to buy fertilizer or are there enough mobilizable reserve substances in the soil? Why is the corn not growing or not growing as well as on comparable sites? The “Basic Characterization” analyses the current nutrient supply and additionally the reserve substances and 5 phosphorus pools. With this analytical program, fertilizer use can be reduced and growth problems can be solved.
Current Nutrient Supply
The analytical program “Current Nutrient Supply” analyses the actual nutrient supply and helps to optimize fertilizing strategies. If the analysis points out a shortage (in macro nutrients and trace elements), the recommended input is declared. This recommendation is based on real differences of existing and required nutrient quantities and not on content classes.
Soil expertise and evaluation
For example, if you want to know if biogas residues sustainably damage your soils or if the desired fertilization effect is accomplished. Additionally, we can provide advice before buying or renting a new field, evaluate inversions to reach your intended crop yield…
