One of the few benefits of this prolonged lockdown has been the proliferation of webinars or online seminars that can be accessed from around the world. Perhaps they were always there, but our limited ability to travel has encouraged us to listen to people we may previously have not known.

Given my interest in soil, I was tempted a few weeks ago to listen in on one of the Cré sessions titled “SOIL – The Essence of Life on our Planet”. The address was given by Dr Rattan Lal from Ohio State University, a man with many titles and distinctions. My interest was based on his knowledge of soils and soil science.
