Preparation and Sampling
Collect Samples: For best results, collect several small soil samples from a depth of 5 – 10 cm (or 10-15cm for shallow-rooted plants) from the area you wish to test.
Remove Debris: Remove, un-decomposed organic matter like roots, leaves, or bark.
Dry and Mix: If the soil is very wet, allow it to air dry on paper. Mix the samples thoroughly to ensure a representative sample, and crush any hard lumps.

Testing Instructions
Place Sample: Place a small amount of the prepared soil (about half a teaspoon) onto the white spot plate provided in the kit.
Add Indicator: Shake a few drops of the Liquid Indicator onto the soil sample.
Mix: Mix the indicator and soil together thoroughly to create a thick paste.
Add Powder: Sprinkle a thin, even layer of the white Barium Sulphate powder from the puffer bottle over the top of the moist soil paste.
Develop Color: Wait roughly 2–3 minutes for the white powder to change color.
Read Results: Compare the new color of the powder with the color chart provided in the kit to determine the pH.

Zoe ★★★★★

I was skeptical about testing my lawn pH, but the depth guide for sampling made it foolproof. Got consistent results across three different spots in my yard.

Matthew ★★★★★

Took soil samples from my vegetable bed at the recommended 10cm depth and the results were clear and easy to read within minutes. The kit comes with everything you need to get started without any confusion.

Elizabeth U. ★★★★★

The depth guide for sampling is spot on—I took a few cores from 5-10cm like it said and the whole process took under ten minutes. Clear, straightforward, and no guesswork about where to dig.
