Do chemical fertilizers actually help in agriculture?

When it comes to the advantages of using fertilizers in agriculture, it’s all about efficiency. Chemical fertilizers allow growers to maximize their crop yield on a specific piece of land — the more the plant grows, the better. Fertilizer works to ensure that each piece of land produces as efficiently as possible.

What is used extensively for the production of fertilizers?
