Luster Leaf 1662 Professional Soil Test Kit with 40 Tests

Some may give some low ratings because, yes, this requires some effort. I do feel a little more confident in the results though, compared to some “easy button” digital products that seem to get results all over the board for the same sample.

So far, so good! Being somewhat of a cheap nerd, I compared wet chemical vs. other kits for determining soil pH, N, P and K. before buying this one. I found this kit easy to use, but perhaps some people will feel overwhelmed by the number of steps that need to be gone through in order to get the readings. Basically, you dig down a couple of inches into the soil you want to test. In this case, it was a bare spot in my lawn. You put various soil fractions in test tubes, add a reagent, shake (and filter in some cases - which the kit makes easy to do), and compare to a color chart. The results came back with what I suspected was the problem - much to acidic a soil and one depleted in N. I took the results and used the inclued chart, bought some fast-acting lime, N and other stuff to kill moss, and applied it to the lawn. So far so good! I am very pleased. The photo shows the test for Nitrogen.

Product is decent. Only issue i had is the small plastic spoon broke and i cannot use it to put filters in or scoop. Seller sent out a replacement so i give 5 stars. I would buy again.

Horrible product. First off, buy the kit you send away for the results. After 4 attempts, we could still not get a good result. The instructions are vague and the test kit contraption thing pieces are cheap and poorly made. It just does not work the way the instructions say it does. Do NOT recommend this product.

This test is probably pretty accurate since you feel like a scientist mixing all the solutions but I have 2 garden beds and they both gave the same results except the PH was slightly different. Depleted in N, sufficient in P, and I’m actually unsure if they are depleted or surplus of the K but they are the same for both beds that had different crops in each. It took me a couple of hours to do all 4 tests on both beds. It just seems like it should be a little easier/faster. I’ve never tested my soil before so I don’t know how accurate it is…I’m just assuming it is because of all the mixing.

Plastic plunger fails and was only useful for a single set of tests. Now I have a kit that is useless.

As far as I know the test were accurate. A little difficult, but after you do it once it very easy. Just read the instructions and do exactly what it says. The dirt needs to be crushed into powder. I put a little bit and put on a sheet of white paper, folded it over and used a glass paper weight to crush it into a powder.

Putting it to archaeological use. I'll keep y'all posted.

The kit and the instructions are comprehensive and I am looking forward in the very near future (haven't used just as it yet as the weather has not been good) to understanding the structure of our soil. Leaves other soil test kits for dead!

This is the second one I've purchased. Very straightforward to use, with clear instructions. Using it for my veg patch.
