Easy way to test plant samples for their required macronutrients.
- 50 tests for macronutrient presence in plant tissue samples
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 plants of choice and perform analyses to determine if nitrogen, phosphorus, and potassium concentration is abundant, adequate, or deficient.
