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 result, the usefulness of the soil may be lost completely. Therefore, when liming, it is important to add only the proper amount for neutralization.

Soil and its Relation to Crop-Production

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 result, the usefulness of the soil may be lost completely. Therefore, when liming, it is important to add only the proper amount for neutralization. Before the application 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 recooended-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 area and 15 cm indepth.
