I want to find out how the mineral content of water affects plant growth. I want to observe the effects of using distilled water, tap water, and salt water on plant growth.
Water contains many minerals which are necessary for good plant growth.
These minerals include iron, calcium, magnesium, phosphorus, potassium, and nitrogen. If a plant is lacking or has too much of any of these minerals the plant may die or not grow into a healthy plant. For instance, if the water has little or no nitrogen or calcium the roots will be large, but the leaves will be small. If there is too much or too little potassium or iron the leaves will be discolored. Experimenting With Plants.
