Soil
I have been working as a scientist on topics of soil biology for almost 20 years. This was mainly about arbuscular mycorrhiza, a widespread symbiosis of plant roots and fungi, and for some years about root knot nematodes. During this time I also tried to obtain a more or less complete picture of soil science. Scientific work on soils is so extensive and dynamic, however, that for many areas I can neither claim to be particularly „on top“ nor „up to date“. Nevertheless I will try to give you a summary and, as always, am thankful for comments, additions, etc.
