I visited two research institutes in New Zealand last week, namely AgResearch and DairyNZ. They are key research institutes in New Zealand in the dairy industry. What I wanted to learn there was about effluent management systems. In Hokkaido, we do need a good guideline for dairy farmers to manage their farm effluent (cow urine and dung basically).
   The visit was wonderful. I was welcomed by many scientists and I could catch up with some of my ex-classmates when I was studying at Lincoln University.
   There are many tools and software available for NZ dairy farmers to use, to manage their effluent. NZ farmers and scientists are working hard to minimize the environmental risks due to the effluent management. As a soil scientist, I am interested in how we can modify these NZ techniques to Japan. In Hokkaido, where I live and where most of the dairy farms are, in Japan, there is a severe winter and heavy snow covers soil surface for 4 – 5 months per a year. We also have a warmer summer compared to NZ. These climatic differences should influence how we manage our dairy farm effluent.
   Now I have a lot of new ideas thus I and my students will work hard, trying to reduce the environmental risks due to farm effluent, in the local scale.
