Just as humans need essential minerals and nutrients for strong, healthy growth, so do the world’s crops. And fertilizers are food for plants. Fertilizers replace the nutrients that crops remove from the soil. Without the addition of fertilizers, crop yields and agricultural productivity would be significantly reduced.

Calcium, magnesium, and sulfur are secondary nutrients needed by all plants for plant structure and energy generation. Deficiency in any of these three nutrients has an impact on crop yield and quality. Therefore, they are the main parameters in most categories of fertilizers.
