   Last week, I was invited as a panelist for a seminar given by Drs Claude & Lydia Bourguignon. The seminar focused on protecting our soils by not cultivating them. This method is often called conservative farming or no-till farming. They alarmed us and many farmers who have attended the seminar that our soils are slowly deteriorated because of the use of chemical fertilizers and of heavy cultivation. 
     They think soil animals and microbes do not survive the cultivation because soil layers (their habitats) are destructed by the cultivation. The loss of soil microbes resulted in the loss of soil organic matter in many agricultural fields in the world, created a lot of abandoned fields. 
     I am very impressed by their talk. They really concern the future of our soil. They also concern the future environment. After the talk, I talked with many of the young farmers who have attended the seminar. Many of them are impressed by the talk and they asked me many questions in terms of soil microbiology. 
     I love young farmers in Hokkaido particularly. They are energetic and they really want to perform farming in a sustainable way. My job is to help them achieve their goals. It is not an easy job but I feel like this was why I came to this University.
