Fertilizers, when used in agricultural facilities and commercial greenhouses, can significantly boost output and appeal. Fertilizers work by providing plants and crops with nutrients they need to grow to their fullest and at a faster rate than achieved through natural processes alone.

Fertilizers may also be more cost effective and time efficient for gardeners and commercial farmers as well. Many fertilizers are inexpensive to produce, and purchasing them to encourage plant growth instead of buying high-quality soil may save significant amounts of money. However, fertilizers have disadvantages as well. One of the main concerns over fertilizers is that they require frequent reapplication.

Fertilizers may cause cumulative harmful effects on humans, animals and environments, such as contaminated water supplies and spread of illness.
