TAKEMURA Soil pH and Moisture Tester

In order to form soil which is able to absorb manure effectively, it is necessary to neutralize the soil, i.e. -by mixing lime with it.
However, if soil liming is excessive, manganese will be depleted, and manganese deficiency will occure. As a result, the usefulness of the soil may be lost completely. Therefore, when lirhing, it is importanto to add only the proper amount for neutralization. Before the aplication of lime the pH value must be determined-the pH reading indicates its hydrogen ion concentration. To determine this value Takemura's simpklified pH Tester is recommended-it has been specifically manufactured of making on-site measuremnets,
*pH values suitable for vegetable growth: these are attached to the tester proper.
*Amount of calcium carbonate necessary to provide soil with a pH value of 6.5, 10 ares in area and 15cm indepth.
