Innovating Science® - Distance Learning: 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 5 tests.
