Electronic Soil Tester

— This Soil Tester is virtually indestructible in its solid state construction, gives accurate readings, will not stain hands or clothing, requires no solutions and is factory calibrated to known chemical standards. In other words, it is well adapted for it's intended use.
--- The pH portion of the tester utilizes the chemical reaction known as oxidation reduction to measure pH within the range of 1 through 9, where pH 7 (neutral) is the pointer's resting point. Its primary function is to quickly discern an acid soil from an alkaline soil and after one minute, a weak acid/alkaline from strong acid/alkaline soil.
----The fertility portion of the instrument measures the soil's Nitrogen, Phosphorous and Potash (NPK) content, in combination. The method used is termed conductometrics wherein a 1.5 volt AA battery is used. The standards by which the instrument is calibrated are as follows:
——-
TOO LITTLE
IDEAL Range
 TOO MUCH
Nitrogen
50 ppm
50 to 200 ppm
 200 ppm
Phosphorous
4 ppm
4 to 14 ppm
 14 ppm
Patash
50 ppm
50 to 200 ppm
 200 ppm
* ppm is defined as parts-per-million
Easy to use...
1. Slide selector switch from "off" position to either "pH Analysis" or "Fertilizer Analysis" position.
2. Collect a soil sample from the area to be tested and thoroughly moisten.
3. Insert probe completely into the soil sample.
4. Within seconds the meter will indicate the pH or fertility condition of your soil. Check the detailed pH prefernce list in the enclosed booklet then seclect the plants suitable for your soil or follow the instructions for correcting your soil condition.
HOW TO USE YOUR METER TO MEASURE -pH
BEFORE TESTING THE SOIL
——If you are preparing to plant a bed of plants, or to plant a crop of fruit, vegetables or shrubs, or to put out grass seed, you will find it beneficial to sample and test the soil in a number of locations in the area to confirm that the soil's pH is generally consistent over the entire area and that it is within the plant's pH range.
1. Remove the top 2" of the surface soil. Break up and crumble the soil underneath to a depth of 5". Remove any stones or organic debris such as leaves and twigs because they can affect the final result.
2. Thoroughly wet the soil with water (ideally rain or distilled water) to a mud consistency.
3. Slide the switch all the way up.
4. Wet probes. Clean thoroughly with special cleaning pad provided.
5. Insert probes into soil up to plastic base.
6. Wait one minute and take reading.
7. Wipe the probes clean and dry.
8. If you are going to make another test, begin at #1.
HOW TO USE YOUR SOIL TESTER TO MEASURE FERTILITY
1. Remove the top 2" of the surface soil. Break up and crumble the soil underneath to a depth fo 5". Remove any stones or organic debris such as leaves and twigs becuase they can affect the final result.
2. Thoroughly wet the soil with water (ideally rain or distilled water) to a mud consistency.
3. Move the switch on the left side of the Soil Tester from its mid-position all the way down until it stoops.
4. Clean probes thoroughly with the pad provided.
5. Insert the probes fully up to the base of the instrument.
6. Where the needle points after 5 seconds in the reading.
7. Slide the switch up to the mid (off) position.
8. Clean and dry probes.
9. Store away.
10. If you want to take more measurements begin at #1.
IF THE TESTER READS "TOO LITTLE":
1. Liquid feed, with a brand of soluble fertilizer that is recommended for the plants you intend to grow.
2. Liquid feed, within 3 weeks after planting or potting and do this every month whenever you water your plants.
IF THE TESTER READS "IDEAL":
Water once a month with a soluble fertilizer that is recommended for the plants you are growing.
IF THE TESTER READS "TOO MUCH":
1. Water thoroughly to leach out the excess fertilizer from the soil.
2. For potted plants, repot with new soil.
3. For greenhouse plants water thoroughly to leach excess fertilizer from the soil.
4. Do not add any fertilizer. You can add manure, compost, clippings, plant wastes, residues, leaves and any other organic matter to the soil.
