Stefan J. Forstner, a Ph.D. at the Austrian Research Centre for Forests (BFW). Stefan is a young scientist who has already published the research works he has been involved in since 2018. Currently, he is working on the "Digital Soil Map of Austria".

In this episode, you get to know about Stefan's past and present research works. Most importantly, he was very open and supportive of the idea of making this episode!

I can't thank enough people who are very open to sharing their knowledge and responsive to my offer! This podcast would not exist without these people. And science keeps evolving, and knowledge keeps being shared (instead of buried with one) thanks to people like Stefan and all my previous guests, including my future guests.

49:04 Why Simulated Soil Drying and Rewetting experiments are cool!
56:23 China changing weather artificially
58:00 A problem with cover crops (sorry for the warning signal)
59:09 Challenges with soil microorganisms
1:06:24 Does Climate Change scare you?
01:08:10 do "Tai Chi"!
01:10:20 My favorite thing about science...
01:12:25 About the meaning of life
01:13:31 Where and how to find me online
 

After a few days later, Stefan also added some information (on one of my questions) in my LinkedIn comment section. So, I decided to copy and paste the comment as it is for people who will find it interesting: 

"I just realized that I did not answer (at least) one of your questions: Overall there are a little less than 12k soil profiles for about 1.3 Mio hectares of agricultural area in Austria. So 1 profile for every 100-110 ha on average. Each profile was judged by the soil mapper to be representative for one "soil form" (= the mapped polygons = areas with the same soil type + similar site characteristics, as I tried to explain). Soil forms ("Bodenformen" in German) can cover from 100 to over 2500 ha each. But still on average 1 profile was dug for every 100 ha. This partly explains why mapping is still ongoing after ~70 years... (but we will finish it within a foreseeable future ;))."

The end of the comment.
