Fertilizers are substances added to soil or plants to provide essential nutrients that help them grow better. They usually contain key elements like nitrogen, phosphorus, and potassium, which are vital for plant health. By using fertilizers, farmers and gardeners can improve crop yields and enhance the quality of their plants. There are two main types of fertilizers: organic and inorganic. Organic fertilizers come from natural sources, such as compost or animal manure, while inorganic fertilizers are chemically manufactured. Both types can be effective, but choosing the right one depends on the specific needs of the plants and the soil conditions.
