why do we apply fertilizers to the soil
Answers
Explanation:
Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium. Fertilizers are simply plant nutrients applied to agricultural fields to supplement required elements found naturally in the soil. Fertilizers have been used since the start of agriculture.
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.
The International Fertilizer Association (IFA) estimate that 85% of the soils globally are deficient in nitrogen(1). 73% of the soils are deficient in phosphorus, whereas 55% lack potassium.
