    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.
