Essential Nutrients

YESTERDAY, TODAY AND TOMORROW

Each time a crop is harvested, it takes some of the soil's nutrients with it. Fertilizers replace those nutrients so the soil can continue to produce healthy crops.

For more than a century, the application of mineral fertilizer has been instrumental in improving agricultural production throughout the world. Today, fertilizers account for more than one-third of all crop yields.

With growing populations, improving diets and declining per capita arable land, sustainable increases in agricultural production will require maximizing crop yields. This can only be achieved with the proper use of fertilizers.
