I have analysed the element of the soil in 13 so called long life and 3 short life village and compared their milligram equivant and also their equivalent ratio. I have find out there very interesting difference between both village, namely the value of pH in long life village showed 5.8∼5.2 and in short life village 4.6∼5.0 and the ratio of Ca-Na 2.0∼3.0 in long life village and smaller than 1.0 in short life village. The ratio of Ca/K, Ca/SO4 of the long life village were higher than that of the short life village, in the contraly that of Mg/Ca, Na/K of the long life village were both lower than that of the short life village. Thus I could described most vividly by graph the difference between both village.
