Crops are the first step in the food chain. Soils which are lacking important nutrients, grow plants with the same deficiencies. This can lead to nutrient deficiency related disorders in people.

By adding specific minerals to the fertilizer, the soil can regain a healthy balance of nutrients.

Let us take zinc for example: 50 percent of the world's soils are marginal or deficient in this important micronutrient.

In humans, zinc is used to activate the growth and development of bones and major organs, and to enable brain functions such as memory, sensory messaging and cognition.
