Researchers discovered hundreds of years ago that soil simply contains mineral nutrients close to plant roots, but the soil itself is not needed for plant growth. Using a technique called hydroponics, you can grow plants in an aqueous solution of mineral nutrients instead of soil. The key to plant growth is a variety of mineral nutrients, including nitrogen, phosphorus, and potassium. If you can add these essential mineral nutrients to the plant’s water supply, you no longer need soil for the plant to grow. Almost any plant can be grown hydroponically.
