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.

Why are pesticides used in agriculture?

The biggest reason why using pesticides seems worth it to local farmers is because they are a cost-effective way to do more business if their produce is prone to pests. The reality is, that by “playing it safe” and avoiding the use of pesticides, the financial loss that professional growers will incur due to the loss of produce is far greater than the expenses required to purchase pesticides and prevent that from happening in the first place. On top of that, by actively and continuously making your crops “disease-proof”, the chance of the produce being infected in the future drops significantly.
