I've had my soil tested through my local extension office, but wanted to do some follow-up, especially on my N-P-K. This test kit will do the trick!

      I used this to test my garden soil. My tomatoes weren't doing too well and I wanted to see what was missing in my soil. Found out there was not enough nitrogen

        Tested soil in raised bed which indicated depleted nitrogen and phosphorous. I added granulated food. Snap peas are starting to sprout! Still waiting for lettuce to sprout after planting last week.

              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!

              Comments about NPK 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.

              is it reliable?

                  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.
