Why do plants need fertilizers?

To grow healthy crops full of nutrients, farmers need to ensure they have healthy soil. 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.

Careful analyzing and fertilizing of crops enables a chain that provides humans with nutritional food:

The nutrients feed the soil

The soil feeds the plants

Plants feed animals and people

The three most common mineral fertilizers are those based on nitrogen, phosphorus and potassium.
