Chemical fertilizers are synthetic substances made from various chemicals that provide essential nutrients to plants. They typically contain key elements like nitrogen, phosphorus, and potassium, which are crucial for plant growth. These fertilizers are often used in agriculture to enhance crop yields and improve soil fertility. Farmers apply chemical fertilizers to ensure that plants receive the nutrients they need for healthy development. While they can lead to increased productivity, excessive use may harm the environment by contaminating water sources and disrupting local ecosystems. Proper management is essential to balance the benefits and potential risks associated with chemical fertilizers.
