* In Iwate, the Soil Project Iwate had implemented measurement at more than 300 spots in 2012 and 2013.
The project activity will be made starting from requested districts. Individuals, groups and any organization
such as school and daycare can participate in measurement of proposed spots. Proposing more than 5 spots are desirable.
The measurement spots will be decided after consultation basically in the same municipality.
