Confused
Now I really don't know what to think!
True that it's a home made test, but I think I did everything fine.
There's PH reagent pastilles and distilled water to add to soil..
I tried to catch colors better than I could, as you can see the two test are showing a color that's not really blue that it's the color indicating ph 7.
In person they were more toward blue/green. Teal. The first pic is the clay soil amended with some peat the past year. The second pic is the soil test where the soil is still the original clay I had found here, it wasn't depositing because it's really all mud (with a horde of earthworms living happily in it).
I'm waiting for the vial to dry then will try the test with a bit of the peat moss I have here (the bag says it's acid) and see if the color change.
I'm really puzzled!
Too bad that the test stops at ph 7 color blue, but in my testing the blue was not even reached.
Sighing!
Thanks for looking!!

same color result for peat moss with (written on the bag) ph 6.5.
So does it mean the soil is not so alkaline as I thought?
We had rains, but the last rain was two days ago and soil is almost dry.

Since you're able to grow a rhododendron, maybe it isn't. Do you have any kind of Ministry of Agriculture, or farm supplies store, there that could do a laboratory soil test? A pH test plus nutrient levels is not usually expensive and could remove the doubts.

Thanks Sue, I have to check because I really don't know.
Tomorrow I'll meet a friend who's into testing water and soils, so I'll ask her.
I always thought clay equals alkaline.
I feel such an ignorant!!!!

Simple test kits can be a big help for a gardener. However, they are often not very good for fine measurements such as the difference between a pH value of 6.0 and 6.5 Even when measuring with a scientific instrument capable of determining a pH difference of plus or minus 0.1 unit, the most accurate measurements would be taken after the solution has been filtered and there are no solid materials remaining in it. The age of the test kit from the date of manufacture (not how long you have had it) can sometimes cause a problem with a test kit results by developing a weak color development, in some extreme cases, an incorrect color.

Many "clay" soils in the southeastern part of the USA are very acidic. It is not unusual to obtain pH readings in the 5.5 - 6.0 range when testing them. Many gardeners in that area must use lime (agricultural grade ground limestone) to bring the pH into the 6.5 - 7.0 range even after adding various organic materials to allow good drainage. If you want to test your test kit, put water in two test tubes and add a drop of vinegar to one and a small amount of baking soda to the other. When you add the colorizing chemical to the tube with the drop of vinegar, it should indicate being acidic (it should turn the water yellow) while the tube with baking soda should indicate being alkaline (a strong blue color or perhaps even a purple).

I hope this helps,
Larry

Larry - I checked the test kit, it's working correctly. With vinegar it became yellow, and with baking soda it was purple.
So I can reasonably assume the soil PH is between 6.5 - 7
I don't think I need a scientific measurement, a good indication of its acidity is fine.
Many thanks!
