  The soil moisture meter KC-300 is a great, 4 in 1 soil survey instrument that will allow you to detect and correct soil problems in your garden, your lawn and your indoor plants. On this page I try to answer quentions I recieve from customers and explain how the meter can be used.  
       
 
To measure soil moisture, remove the plastic cover from the tip of the soil moisture meter KC300
 Q: The Soil Moisture Meter KC-300 only seems to measure temperature, the moisture and pH reading stay the same, no matter what soil I test.  
 

A: The tip of the soil sensor is protected with a white plastic cap, remove this cap before you measure. After the measurement, clean the tip of the soil moisture meter and put on the cap to protect the sensor during storage.

Q: The Soil Moisture Meter only seems to measure the pH value of the soil.

  
  A: Please use the switch on the back of the soil moisture meter to change from pH mode to the temperature, moisture and light measurement mode. When the switch is on the left side, the meter only measures pH, when you move it to the right side the soil tester will read moisture, soil temoerature and light level.  
       
    Q: I have noticed that the meter is cheaper on your website than it is on amazon or ebay?  
    A: Yes, amazon and ebay charge very high seller fees, which can add up to 20% of an item price. They also set shipping fees and other rules. I don't have these costs when you buy directly from my website. If you have bought on amazon and ebay, please understand that I can not refund the difference, since I had to pay fees.  
       
    Other Tips and Suggestions:  
    The Soil Moisture Meter KC300 runs on a single 9V battery. Please remove the battery from the soil tester when you store the meter for the winter.  
       
 
Mark the probe of the soil moisture meter in 1 inch increments, this will allow you to test the soil in a certain depth.

You can use a black permanent pen to mark the probe of the soil moisture meter in 1 inch increments. Start at the white plastic ring near the tip of the moisture probe. This will allow you to measure the soil moisture always in the same depth or in different depths.

Experiment suggestion:

Before you water your lawn, mesure the moisture of your soil in 1, 2, 3, ...7 inch depth. Then water the lawn as you normally do. After the watering, measure the soil moisture again in all the depths and compare the readings.

Then monitor the drying in each depth over several days.

Comparing the readings will allow you to judge if you overwater your lawn. For example, if you permanently measure very wet conditions in 7 inch depth you probably overwater the lawn.

If the soil moisture after the irrigation only changes in the first 2 inch you probably underwater.

The soil moisture meter KC300 is brand new and I got the first unit in January 2010, so I have not a lot of experience yet, but I will report my experience in the coming weeks. I believe that you can optimize the irrigation using this soil meter and also save a lot of money, since in many areas of the US watering the lawn is the biggest driver of water cost. And probably different watering strategies are needed in different parts of the country, depending on grass mix.

Also, if you are aware of discussions on this topic in lawn care forums, please let me know and I will post links here. And feel free to link to this page.
