Great product - useful for really pinpointing soil issues. However, we would love for you to carry refill capsules, as they are nearly impossible to find.

Comments about NPK Test Kit:
Product is easy to use, but time-consuming and the color scales on some tests are difficult to read against the sample. Good for a quick look, but not nearly as informative as a professional soil analysis.

Comments about NPK Test Kit:
We had moved 2 years ago, I was delighted to see a garden spot. However I was rather disappointed with the veggies when they finally came up. I had tried a regular fertilizer, and everything was still small and few veggies per plant. The 2nd year was worse, pretty much just the weeds grew. This year I tried the test kit first. The test was very easy and fun, the directions were clear and well written. I could not believe the results! The handy info brochure explained the correlation between where the soil was too high or too low and what I saw in the garden. It also gave me information on pH for specific plants, and how to correct the N,P,K and pH findings. When I went to get my supplies to correct the soil, the gentleman who helped was also very impressed with the information the soil test kit gave me, apparently many kits aren't as informative.

Comments about NPK Test Kit:
I have heavy clay soil, so have over the years ammended with sand and quite a bit of mulch. I've had good peas, tomatoes, peppers..., but I could never get root crops to grow. With this test kit I found the bed was totally depleted of nitrogen. Added a bag of mulched cow manure, and for the first time I actually have 2-inch onion bulbs. More improvement coming, but the test was extremely helpful. I really liked having the full spectrum to test.
The only downside was the time required to let the soil settle. (typical of clay and not fault of the kit!) It was still faster and cheaper than sending off samples to a lab.
