Fertilizers are essential substances that provide vital nutrients to plants, promoting healthy growth and higher yields. They typically contain key elements like nitrogen, phosphorus, and potassium, which support various plant functions. Organic fertilizers, such as compost and manure, enrich the soil with natural nutrients. Inorganic fertilizers, on the other hand, offer a concentrated form of nutrients for faster results. Proper use of fertilizers enhances soil fertility, boosting agricultural productivity and supporting sustainable farming practices.
