Manage nutrition to optimize plant growth.

Management should include

  • identifying and adjusting micronutrients for selected crops
  • identifying and adjusting macronutrients for selected crops
  • identifying soil and soilless media
  • interpreting soil test results
  • identifying and applying sources of nutrients, such as organic and inorganic fertilizers
  • identifying the level of soluble salts in the soil and soilless media
  • identifying deficiency and toxicity symptoms of nutrients (e.g., nitrogen, phosphorus, calcium, zinc, sulfur, magnesium)
  • explaining fertilizer recommendations
  • recommending methods of fertilizer application, including
    • pre-plant fertilization with controlled-release fertilizers
    • fertigation
    • surface application of water-soluble fertilizers.
