How are fertilizers used?

Fertilizers are added to crops in order to produce enough food to feed the human population. Fertilizers provide crops with nutrients like potassium, phosphorus, and nitrogen, which allow crops to grow bigger, faster, and to produce more food. However, plants and animals cannot use the nitrogen gas in the air.

How is fertilizer applied to crops?

Fertilizer can be applied in several ways including broadcast (with or without incorporation), seed-placed, banded, foliar, or fertigation. Broadcast applications, especially without incorporation, carry the greatest risk of nutrient loss.
