Interested in knowing where your soil health is for growing your favorite plants? This test allows you to quickly and accurately test the existing pH, nitrogen, phosphorus and potash levels in your soil in a fun way!

The Luster Leaf Rapitest Soil Tester contains 10 tests - 2 nitrogen, 2 phosphorus and 2 potash, and 4 pH.

The packaging contains detailed instructions along with the recommended levels of each for a variety of plants: fruits, veggies, herbs, trees, shrubs, plants, flowers, grasses and lawns. 

All plants have a pH preference, so its important to know their requirements.  They require the correct pH level (the relative amount of hydrogen in a substance) to control how they utilize the nitrogen, phosphorus and potash available to them.

Nitrogen is directly responsible for healthy green leaves.

Phosphorus is vital for a strong, supportive root system.

Potash is essential for flower and fruit development.

Test results allow you to amend and fertilize appropriately, ensuring the best possible growing results.
