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

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.

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.

Easy to use as it comes with all the gear needed to process samples, not to sure on accuracy as I've got no equipment to confirm.

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

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.

The instructions were easy to follow and the kit was easy to use, however the results were hard to read. The results didn’t really match any of the the colours on the chart and could have been interpreted differently depending on how you looked at it, sometimes with a huge difference in the outcome. I’m also not convinced of the accuracy. I tested an area of soil which has vigorous nettle growth, expecting a high Nitrogen reading, but according to the colour chart it was either depleted or deficient.

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.

All the test results indicated deficiency in N and P, even when I tested fertiliser as benchmark. A waste of time and money.
