What is the importance of fertilizer in agriculture?

The role of fertilizers is to increase yield and ensure healthy produce by supplying the right balance of nutrients to the soil. “Without fertilizers, the soil would be depleted and therefore plants would be particularly difficult to grow. They cannot survive on water alone, and nor can we.

How can fertilizers be beneficial?
