There are 17 chemical elements that are known to be essential for plant growth, 14 of these elements come from the soil. Do you know what your corn needs to not only survive, but thrive?

To be classified as “essential”, the element needs to meet the following criteria.

  • The plant cannot complete its life cycle (seed to new seed) without it.
  • The elements’ function cannot be replaced by another element.
  • The element is directly involved in the plant’s growth and reproduction.

It is important to understand the principles of soil fertility to efficiently manage corn nutrients, corn production, and environmental stewardship. Each essential plan nutrient is needed in different amounts by the plant, each varies in mobility within the plant, and varies in concentration in the harvested mature corn plant components. Knowing the relative amount of each nutrient by crop and the amounts removed with harvest is useful for calculating the amount of fertility that will need to be added to the soil to maintain optimum harvest levels.


In this issue you will learn the following:

  • How plants uptake nutrients
  • How nutrients move within the plant
  • Nutrient Deficiencies symptoms in corn
  • Developing Fertilizer Recommendations, Understanding Nutrient Uptake and Partitioning
  • Fertilization of Macronutrients in Corn Production
