These handouts, in English and in Japanese, were prepared for a seminar I gave at Takarazuka Golf Club. 

The topic was irrigation of creeping bentgrass greens in summer, and I discussed soil moisture content, how frequent irrigation can actually be used to maintain a lower soil moisture content than infrequent irrigation, how I would not syringe greens to cool them if I were a greenkeeper today, and just how much the soil and surface temperatures change when ice, ice water, and tap water are applied to creeping bentgrass in summer.

I also showed some video clips of water movement in soils.
