I am very happy about
I am very happy about my purchase and excited that I can get an accurate assessment of my soil nitrogen levels for my plants. This test is what I have been looking for regarding nitrogen testing at an affordable price. I am now able to do multiple readings quickly at home without having to wait for a lab to get back to me. I am able to make an intervention on a timely basis. I only wish that there were such a test for soil potassium and phosphate levels as well.
