Comments about NPK Test Kit:
So I order 18 tons of organic topsoil to fill my new (and huge) garden of raised beds, and I figure I'd better not take the seller's word for it. I should know for myself what I'm feeding my plants. Got the test kit. Did all the tests. Lo and behold, my 18 tons of glorious dirt has barely a trace of phosphates. Needed to be acidified, too. While I'm not impressed with my expensive dirt, I love the test kit!

[...]. Most of the instructions are vague and assume knowledge of how much soil to add to test the soil. Most instructions are not in English.

Comments about NPK Test Kit:
After years of failing to send out soil samples, we found this kit and gave it a try. Have used it on three different samples from very different areas of our 3 acres, and the results are pretty similar, which makes me a little suspicious. Too soon to tell if what the test recommended is correct. But it's easy to use, and if the results are reliable, then it's worth it. After a month or two, I'll return to report how the plants did.
Pros
- It did give results
Cons
- Messy
Best Uses
- Vegetable Gardens

Comments about NPK Test Kit:
The test kit said I needed Nitrogen and the ph was very high. I added the prescribed ingredients and my plants do look much better this year. So I guess it told me the right things. We'll see how it turns out.

Comments about NPK Test Kit:
I use this kit to test the compost coming out of the bin before I place it on my garden. I can therefore fix the potential problem by adding the needed item to my compost tumbler, turning it a bit and use the finish compost on my garden in a day or so.
