What Your Students Will Learn

How many elements are essential to both plants and humans?

Humans and plants rely on 15 of the same elements for survival. These elements are: calcium, carbon, chlorine, copper, hydrogen, iron, magnesium, manganese, molybdenum, nitrogen, oxygen, phosphorus, potassium, zinc, and sulfur.

Why is it important to improve the health of our soil?

Soil containing the proper balance of nutrients ensures efficient land use and the environmentally and economically sustainable production of nutritious foods for our growing population.

How much of the world’s land is available for food production?

Only 1/32 of our earth is suitable for farming. By the year 2050, our world's population will top nine billion people, requiring more than 11 billion additional acres of cropland to feed the world at our current food production rate.

What can farmers do to preserve our environment’s forests and other fragile resources?

There is a great deal of science and technology behind the proper management of nutrients. To prevent nutrient losses to the environment and to promote the best use of our land resources, farmers must rely upon soil and plant tissue analysis as well as prescription-style blends of nutrients to ensure plant needs are met, and the environment is not put at risk.
