About this item
Easy way to test soil for the macronutrients that grow healthy plants.
- 50 tests for macronutrient presence in soil samples
- Aligned with GLOBE protocols
Plants need a variety of nutrients and minerals to grow and maintain overall health. The 3 main nutrients that plants require to survive and thrive are nitrogen, phosphorus, and potassium (also known as NPK). In this activity, students will extract nutrients from a soil sample and perform analyses to determine if nitrogen, phosphorus, and potassium concentration is abundant, adequate, or deficient.
Find problems with plants before they happen.
