Chemical fertilizer is a substance that provides essential nutrients to plants, helping them grow more effectively. These fertilizers typically contain key elements like nitrogen, phosphorus, and potassium, which are crucial for plant health. They are often manufactured through industrial processes and can be applied to soil or plants to enhance crop yields. Farmers and gardeners use chemical fertilizers to improve soil fertility and boost plant growth. While they can lead to increased agricultural productivity, excessive use may harm the environment by causing soil degradation and water pollution. Sustainable practices are important to balance the benefits and potential drawbacks of chemical fertilizers.
