How much phosphate fertilizer is used in the U.S. each year? According to USDA’s 2016 estimates, about 9.4 billion pounds of phosphate is applied on an annual basis in production agriculture. Research also shows that even under the best soil conditions, only about 20% of the phosphorus applied is available for plant uptake.

In this course, you will learn about the driving factors of nutrient availability and how to overcome nutrient tie-up and loss. You will review the three main factors that affect nutrient availability:

  1. Soil pH
  2. Organic Matter
  3. Cation Exchange Capacity

The presentation will review how chelation helps free up the micronutrients and increases phosphorus availability.

Course lessons:

  • Phosphorus Management (29 min)
  • The Newest Solution to Phosphorus Tie-Up (2:22 min)
  • Using Trivar to Maximize Your Broadcast Fertilizer for More Available Phosphorus (1:32 min)

By successfully completely this 40-minute course, you will be able to share with your customers:

  • The different phosphorus forms and how phosphorus becomes bound in the soil.
  • The tools and technologies to help manage phosphorus availability in the soil.
  • How chelation works and why the ortho-ortho EDDHA chelate is recommended for long-term nutrient chelation.
  • What a phosphatase enzyme is and how it helps free phosphorus from organic matter in the soil.
  • The value of micronutrients, like Zinc and Boron on plant growth and development.

Supplemental materials include:

  • Sales Materials
    • Trivar Sell Sheet
