Luster Leaf 1601 Rapitest Test Kit for Soil pH, Nitrogen, Phosphorous and Potash, 1 Pack

I hadn't realised until I tried this product out on our allotment just how improverished the soil was. The pack was very easy to use and the instructions were clear. I can now safely add the nutrients in the right quantities for my vegetables.

Seems to work ok a bit of guess work required to match colours as close as posible to chart. Not many tablets included so works out expensive.

Our garden soil is poor quality. Many plants won't grow at all or just come up stunted. Use of this kit identified the problems. We used natural supplements to enrich the soil and had a great display of blooms the first time in years. Easy to use for us amateur gardeners.

Great for Greeks; just disappointed my soil was really good and did not need anything ;-)

I bought this specifically to test for phosphate. In principle I found the testing procedure well described in the instructions and fairly easy to carry out - as some have mentioned it is quite tricky to open the capsule of reagent and get it all into the test chamber without spilling. However I found it impossible to get results for the phosphate test. The powder reagent didn't seem to dissolve properly leaving a cloudy test solution, and also tended to form a precipitate of dark/blue black flakes - this made it difficult/ impossible to do a colour match. I did contact the manufacturer and although they replied they said that they couldn't help. It's a US kit and while the basic kit was delivered at a reasonable price it seems impossible to get replacement reagent capsules delivered to the UK at a reasonable price.

Although the actual test kit was easy to use and the results reasonably clear I found that I had to watch a video on YouTube to use the test kit properly. The user instructions on the printed card supplied were not clear and somewhat difficult to interpret.

Product as described. Seems very good value for money, but I have not used it yet.

Do not buy this product; it came like this upon receipt.

I took a sample from my veggie garden to see how my soil is. The tests were easy to perform and the results were very clear. I am hoping that this year were have a bountiful harvest come fall because I amended the soil as per the results. Fingers crossed!

It shows pretty close results compared to professional lab test. What type of nitrogen it is testing for would be good to know though. To apply the test capsule reactants to the tiny test chambers is a fiddly, fumbly business. There should be a kind of hopper coming with it, especially since the base of the test containers are not designed for a stable stand. I tried to find out wether you can buy replacement capsules. If I have to buy an entire new set after ten tests than this is unsustainable plastic waste.

Tut was es soll, funktioniert, kann natürlich nicht überprüfen, ob die Testergebnisse stimmen.

Tres bien

Great kit altogether, super convenient. I found that it took up to 12 hours for the solution to change colour completely, so be patient.
