Detail Takemura DM-5 Soil PH & Moisture Tester ( Soil Tester)

Chart No.1

List of Optimum pH Index for Some Farm Produces :
pH 7-8	Barley, Spinach, Sugar Beet, Ground-Nuts, Onion, etc
pH 6-7.5	Rye, Wheat, Peas, Sweet Potato, Turnip, Clover, Egg-Plant, Burdock, Tobacco, etc
pH 5.5-7	Soya Bean, Rape (cole), Red Bean, Radish, Carrot, Tomato, Corn, etc
pH 5-6.5	Rice-Plant, Dry-Land Rice, Potato, Taro, etc

To judge f the proper quantity of lime has been sprayed for neutralization, detection is required to be made about a week after the lime spraying. Volume of lime to be sprayed for neutralization varies according to quality of the soil involved.

Chart No.2

The quantity of lime needed to raise, by one unit pH index of soil toward Alkali side or Alkalization (10,700 square feet (990 square meters of 1/4 acre))

Nature of Soil	In case of Weak Humus	In case of Medium Humus	In case of Rich Humus
Sandy Soil	64 kgs. (140 lbs)	128 kgs. (280 lbs)	200 kgs. (440 lbs)
Minute Soil	95 kgs. (210 lbs)	188 kgs. (415 lbs)	290 kgs. (640 lbs)
Sand Soil	188 kgs. (415 lbs)	315 kgs. (700 lbs)	450 kgs. (1,000 lbs)
Medium Soil	315 kgs. (700 lbs)	375 kgs. (825 lbs)	469 kgs. (1,030 lbs)
Sticky Soil	375 kgs. (825 lbs)	469 kgs. (1,030 lbs)	533 kgs. (1,170 lbs)
Humus soil in case humus volume is 15% up: abt. 450 kgs. (1,000 lbs) - 900 kgs. (2,000 lbs)

Features

Being of electric generation system with the earth. no chemical, distilled water, and/or electric power such as storage battery, etc. is needed.
Measuring is most simple, the desired pH index being shown by merely inserting the meter into soil.
The quantity of lime to be applied is readily ascertained.
Compact in size, elegant in style and handy to carry.

Care to be Taken in Handling and Measuring

When it is desired to put pointer needle to pH7 position, take the lid and glass off and carefully turn the screw on the under part right and left and set correct position. Do not turn strongly.
Insert the tester vertically and let the soil contact compactly with the electrode by foot. If the soil does not come in contact completely with metal parts on both of the tster, the pointer needle vacillate left and right and will not settle.
Keep the electrode clean and free from rust. When oxidation takes place on surface, sensitivity becomes weakened and the needle will not point to accurate pH and humidity indexes. When rusty, polish with sand-paper or sand before and after using.
If high voltage electric pole, etc. be near the soil, avoid to measure in such position since it is probable that the pointer needle will point to higher pH and humidity than the true indexes, in relation to earth electric current, etc.
Bring designed to harness soil's electricity generating power for its functioning, index comes more or less different depending on pressure by foot and moisture degree, and so it is ideal if average index figure is sought by doing measuring 5-6 times.
Handle carefully and never drop, oscillate strongly.
