CIA005J-JAPAN DM-15V2 SOIL PH & MOISTURE METER TESTER - MADE IN JAPAN (FIX TYPE DIRECT POKE IN)

Category: Moisture meters

 

  • Soil PH & Moisture Meter An excellent concept, the Soil Tester is a fast and simple method of obtaining accurate values of both soil pH and moisture levels. The metallic electrode is simply inserted into the soil and the moisture or pH level can be checked on the dial. No more messy chemicals.

Used by professionals world-wide.Relative Tolerance of Vegetable crops to soil acidity and the approximate range in soil reaction desirable for good growth

The vegetables in the slightly tolerant group can be grown successfully on soil that are on the alkaline side of neutrality. They do well up to pH 7.6 if there is no deficiency of essential nutrients. Calcium, phosphorus, and magnesium are the nutrient most likely to be deficient in soil more acid than pH 6.

SOIL AND ITS RELATION TO CROP-PRODUCTION
In order to form soil which is able to absorb nutrients effectively, it is necessary to neutralize the soil, i.e, by mixing lime with it. However, if the soil liming is excessive, manganese will be depleted, and manganese deficiency will occur. As a 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 simplified pH Tester is recommended-it has been specifically manufactured for making on-site measurements.

* 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 is 6.5,
10 Acres area and 15cm indepth.

HOW TO USE THE pH METER, common to the DM-13 and DM-15
1. If the soil to be tested is dry or contains much manure, the meter will indicate a correct pH
value. Therefore, sprinkle about a bucketful of water on the soil, and wait for 20-30 minutes, before testing.
2. Before using the meter, be sure to thoroughly polish its metallic surface with a piece of whetting cloth. When using a brand-new meter, be sure to insert it into the soil a few times in order to remove the oily impurities from it’s metallic surface.
3. Insert the meter directly into the field or paddy soil under consideration. Completely embed the metallic surface and tamp down the surrounding soil so that it adheres closely to the meter’s metallic electrode surface.
4. About one minute after inserting the meter in the soil, the pointer will cease to deflect-the-pH value of the soil may then be read. Moisture content, or the pH reading. It is therefore ideal to take an advantage of several measurements.
5. The meter may sometime register different values depending on the soil condition, such as, adhesion to the meter’s metallic surface moisture content, or the pH level. It is therefore ideal to take an average of several measurements.
6. In order to determine whether or not liming has been properly done, after one or two weeks mix the soil well and measure its pH value.

HOW TO USE THE DM-15, either as pH or moisture meter
When the DM-15 is inserted in the soil with the white button on it’s side left un-depressed, it works as an acidity (pH value) meter. When the white button is depressed after it has been inserted in the soil, it works as a moisture meter.

HOW TO USE THE DM-15, as a moisture meter.
Soil moisture control is extreme importance. Soil moisture is usually express in units termed pH, a generally unfamiliar term to people who cultivate. However, Takemura’s tester, which combines a pH with a moisture meter, is easy to use-soil moisture can be determined at single glance.

1. Insert the meter’s metallic electrode in the soil completely, while positioning the electrode as near crop roots as possible.
2. Scale division range from 1 to 8, each of which reads the moisture value according to soil condition.
3. The need for water can be determined by the position of the pointer.
