My pH is very high and I???ve been using ammonium sulfate to lower it. The local elevator charges $25 for a soil test so this device looked like a quick and easy economical way to test pH.

What is the proceedure for testing the soil? Some you have to put soil in water to test.
Tiana on Jul 20, 2016
BEST ANSWER: Following the directions included with the product, this meter is intended to be used in the soil in the ground/container. For best results, test soil that is slightly damp. The meter will not give an accurate reading for soil that is removed and immersed in water.

Accurate if used properly
Incredible value for the $. works perfectly IF used properly. must be submerged in WET soil (doesnt have to be soaked) and must be OFF until it is IN the soil. Good luck!

Saved my lawn
Two years my lawn sodded with Zoisa grass. The sod company said the lawn needed lime every year so I added lime per their instructions. The lawn started to wither. I tested with litmus strips and came to no conclusion. Finally I bought the soil meter and it read 8.9 at many spots. Soil that didn't have added lime was 7.2. I corrected by adding sulfur. The soil meter is very quick and easy to use, just be sure the soil is a little damp.

Make sure you turn it off.
Works really fast. Liked it till I forgot to turn it off. Needs new battery.

Cheap product
The batteries the product came with were dead. Product still would not work with new batteries. The contacts in the battery compartment had to be bent to make contact with the batteries so it would work. Display is very hard to read.

Didn't really work
Sorry, but the product almost always gives me 7.0 reading. And since there are no instructions that come with the product I am not sure if I am doing something wrong.

Great product.
While awaiting delivery of two dozen rose bushes, decided to check the PH in our soil. We have a newly constructed house with no prior plantings. The Rapitest worked beautifully. The Basic Meter is sufficient for our needs.

pH Meter
This meter seems to work well and is very helpful. I'm still getting used to keeping the proper soil for blueberries. I recently replanted them with 1/3 peat, 1/3 bark and 1/3 acid plantng mix. Wish me luck!
