Luster Leaf® Rapitest® Digital Soil Test Kit is a soil testing system designed to quickly and easily measure soil pH, Nitrogen, Phosphorus, and Potash levels. It helps simplify soil testing by providing clear insight into nutrient levels, supporting better plant care and fertilization decisions. At the heart of the kit is a patented digital soil tester with an optical soil test chamber that recognizes the colour hue specific to soil pH and nutrient levels. Tests are performed using four colour-coded test tubes with matching reagent capsules, and a dropper is included to transfer the test solution.
The kit also features a convenient test tube holder for use while colour develops. It includes 25 reagent capsules - 10 for pH and 5 each for Nitrogen, Phosphorus, and Potash - along with instructions, fertilization guidelines, charts, and pH preferences for over 450 plants.
