What is "fertilizer"?

Fertilizer is a substance added to soil or plants to provide essential nutrients that help them grow better. It can be made from natural materials, like compost or manure, or synthetic chemicals. Fertilizers typically contain nutrients like nitrogen, phosphorus, and potassium, which plants need for healthy growth, strong roots, and the ability to produce flowers or fruit.
