Soil Test Kit – pH, Nitrogen, Phosphorous & Potassium Testing

The Rapitest Soil Test Kit makes it simple to evaluate soil quality for gardening projects and science investigations. Ideal for homeschool botany studies, classroom plant experiments, and backyard gardening, this kit allows students to analyze key nutrients that directly impact plant growth and health, or simly to evaluate the soil composition of a garden bed.

Test soil for four components:

• pH level (acidity/alkalinity)

• Nitrogen (N)

• Phosphorous (P)

• Potassium (K)

Each of the four easy color-comparison tests can be performed up to 10 times, allowing for repeated trials, comparative soil sampling, and structured data collection. Students observe color changes and match results to the included chart to determine nutrient levels.

This hands-on soil analysis kit supports lessons in plant biology, environmental science, agriculture, and experimental design. A practical tool for studying how soil composition affects plant growth in homeschool programs, co-ops, and classroom science labs.
