Why are fertilizers used in agriculture

Put simply – we use fertilizer to:

  • Provide nutrients not available in the soil.
  • Replace nutrients removed at harvest.
  • Balance nutrients for better produce quality and higher yield.

Fertilizers replace the nutrients that crops remove from the soil. Without the addition of fertilizers, crop yields and agricultural productivity would be significantly reduced. That’s why mineral fertilizers are used to supplement the soil’s nutrient stocks with minerals that can be quickly absorbed and used by crops.
