Why is it necessary to use fertilizer in agriculture?

The use of these valuable materials can enhance:

  • water quality
  • pollution prevention
  • sustainable agriculture.

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 do farmers use fertilizers?

What are the advantages of manure and fertilizers?

  • It makes the soil porous and facilitates the exchange of gases.
  • The texture of the soil improves.
  • The number of microbes increases in the soil.

Why is fertilizing important?

Without fertilizers, nature struggles to replenish the nutrients in the soil. When crops are harvested, important nutrients are removed from the soil, because they follow the crop and end up at the dinner table. If the soil is not replenished with nutrients through fertilizing, crop yields will deteriorate over time.
