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!

              [...]. 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.

                  Needed more instructions, larger print. It was so small difficult to get dirt in and wasn't certain where to put it.

                  I have used it 2 times I will run out of indicater before the summer is over And that would be tragic for something that works so well.

                  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.

                      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.
