Budget Soil Test Kit

Luster Leaf Rapid Test Kit

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

The Luster Leaf test kit not only measures pH. It can also tell if your soil lacks nitrogen, phosphorus, or potassium. These comprehensive results make this kit one of the best soil pH testers.

Luster Leaf uses capsules instead of test strips. The powder within the capsule is combined with the soil and water sample. The solution will turn colors, indicating the soil’s pH.

This process is repeated to determine NPK levels. The kit only comes with 40 capsules, making it less budget-friendly than the strips. But, you’re getting to know more about your soil than pH.


  • Determines pH and NPK levels
  • Easy to read


  • Pricier than test strips

It’s a little more work than sticking a probe into the soil, but the results are usually clear and accurate.

  • Cost-friendly


  • More work than a probe tester

Frequently Asked Questions

What is the best soil pH tester for me?

The best soil pH tester for you will depend on your gardening habits. Are you regularly checking your soil’s pH throughout the season? A probe tester may save you money in the long run.

If you are just doing an initial test of one area, a chemical test kit may benefit you better. Professional send-off kits are also a great idea for this.

The way I see it: the more you plan on testing pH, the better a digital or analog probe tester would be. Probe testers also work well for testing houseplant soil and potted plants.

How deep should I read my soil?

Test your soil at about four to six inches deep. If your soil is especially tough, take a small trowel and break up the soil. This should allow you to access a sample at that depth.
