Innovating Science® - Plant Tissue Macronutrients

Plants need a variety of nutrients and minerals to grow and maintain overall health. The three 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 your choice and perform analyses to determine if nitrogen, phosphorus, and potassium concentration is abundant, adequate, or deficient. Kit contains enough materials to perform 50 tests.
