Evapotranspiration (ET) calculator in Japanese

The evapotranspiration (ET) is a useful value for turfgrass managers.

 [This calculator][2] using the Hargreaves equation to estimate ET_o is now, thanks to translation by Yukio Ueno, [available in Japanese][3].

Knowing the ET_o and the ET_c allows one to have some idea of the probable consumptive water use of the grass.
