Luster Leaf 1605 Digital Soil Test Kit for pH, N, P and K, 1

It needs capsules. Product comes only with 3 sets of 5 capsules. U need one capsule for each type of test. 1 for potassium 1 for phosphorous, 1 for ph. Product detail must include this information.

I have used the product and find it ok.

It was delayed but received.

Very good soil test. Please note: you must run the test in a dark place, otherwise the reader will show false results. This happens due to fact that the reader works with color recognition, which can be affected by strong light passing through the green cover.

I was under the impression from lack of research on my own part- however this kit only helps determine the color change it does not read levels from the soil alone. You still need capsules to add to soil testing and then put them into the machine to read the color- which really you can do with the naked eye. It did help me diagnose my soil as nitrogen only depletion and now my garden is thriving since I was able to fertilize with a nitrogen only formulation to correct the imbalance. Great if you are novice or trying to figure out what is up with your soil- but the cheaper kits without the machine will also do the job just fine.

el producto llegó antes del tiempo indicado que eran 20 días hábiles. además no mostró fallas. fácil de usar y sin complicaciones.

I bought this unit because it was in the top 3 of reccomended pH testers. But you cannot buy the capsules in the UK, I emailed the makers in America and they cannot give me a suppler in Europe even. So do not buy this white elephant.

Unit is easy to use, just don't get reagents mixed up. I found the analyzer to be quick and easy to use. Checked 2 different sections of my lawn and unit reported depleted Nitrogen and Potassium, deficient Phosphorous, unit was consistent. I know what fertilizer and other lawn nutrients I use and what they do. The readings for the Nitrogen appear low as I use a Nitrogen enhanced product and was used 2 months in advance of sampling. I will do more spot checks/sampling as I only do small sections (2 sg ft) now to see how they react to treatment. Better this way to calibrate how much and what to use, saves on material and waste if doing whole lawn with unknown results. Easy once you get the hang of it. My lawn is always a greenish/blue colour after June. I'm making adjustments to further enhance growth and thickness/colour and will adjust accordingly. I think it's money well spent.
