Having used a water chemistry test kit for many years (no I don't have PhD just a Masters), I see that more or less nothing has changed since I used an ancient kit for my testing 20 years ago. It's ridiculously easy to do the testing, and I am quite sure the solutions are identical to those I used. Since I am not an idiot like Mr. PhD I made up some simple solutions to test the accuracy of the kit. Since the tests give results in mg/l for the nutrients that's ppm so the compounds that are actually measured (e.g. NO3 for nitrogen)can be added to plain water to approximate the concentrations in the tests. Long story short the results were close enough for government work. I didn't find it all that flimsy, although I did crack one of the sample tubes at the top trying to pry the plastic lid off. The results were a bit iffy to interpret but so are the same tests in other test kits.

I am guessing that the reviewers either didn't let their samples completely dry, which will effect the results since you would actually be measuring the contents of the groundwater AND the soil, not the soil. Or they didn't pulverize the soil sample into dust, which it definitely should say on the instructions. You can't reliably extract the nutrients from chunks of dirt. I dried mine in the sun for a few hours then smashed them with a plain old spoon before putting them in the test tube. I can't give the kit 4 stars because of this. Also if you are submitting samples to get tested in a lab you have to virtually duplicate the sample. Same hole, same depth, or your results won't exactly match. also as the kit suggests you need to take multiple samples and average the results. I took 8 samples, 1 from each of my beds.

I've had soil tests conducted using state soil test services, but tried this kit for lawn and garden maintenance to get around a 6 - 8 week lead time. The tests are easy to conduct, the results are proportional to typical state results including 5 samples of lawn and garden yielding distinctly different results. Ph results are on a standard numeric scale 4.5 to 7.5 in 7 increments. Nitrates, phosphorus and potassium are each reported on a 5 increment scale from low to high. It is easy to discern where test samples fall on the scale.

The booklet provides guidance in interpreting readings and how unacceptable readings are corrected, leaving specific instructions for product use to the brand company. In the case of generic substances like lime, the booklet provides a table indicating pounds per 1000 square feet based on soil type and consistency. The booklet also provides extensive lists of plants and flowers suitable for which Ph environment and does the same for grass types.

Someone said the tester does not provide numerical values for the relative scale. This is a $20 consumer test kit. A soil test lab can report index scale or parts per million by using atomic absorption spectrophotometers, Inductively Coupled Plasma Spectrometers (ICPs), Alpkem Rapid Flow Analyzers, Lachat Flow Injection Analyzer; and colorimeters, literally many hundreds of thousands of dollars in test equipment and those results do not interpret into treatment or what to buy at a garden center.

The test is easy to use, accurate and provides more than enough information to lay out a successful and cost effective treatment plan for a lawn and garden.

Used it on my garden and yard. Then friends' gardens with different results. The product gave about the same results as an earlier $40 test by a licensed lab.

I ordered this kit because I was tired of pouring money into trying to get a decent lawn without knowing what it really needed. The kit arrived promptly and was well packaged. I had previously obtained soil samples from the areas of interest so they were dry when the kit arrived which allowed immediate testing.

The instructions are fairly clear, but be sure to read through ALL of the testing instructions completely before starting to run any tests. The tests do take a little time to allow the sediment to settle before obtaining the actual liquid need for testing. This is a key point so make sure to let things settle enough once you have added the necessary chemicals for each specific test.

The results are fairly easy to read, but are generalized with a range of "high", "medium" and "low" for each chemical. The Ph test is more specific and gives a reasonable range to work with. Just take your time and it will work for all tests, Ph, nitrogen, potassium and potash.

Overall, I am very satisfied and am anxiously waiting for results from my more informed efforts to get a decent lawn.

My soil it deficient in many nutrients and this kit helped me find out where to start. Iron is one area but reading about iron deficiency told me that I probably have sufficent iron in the soil but lake sulfur to help the plants use the iron. Also my soil is too alkaline, its nice to know where to start. Great product for a starting point and was shipped quickly.
