Ammonium Analysis for Plant Leaves

Ammonium is a critical inorganic nitrogen source for plants, playing a key role in growth and nutrient management. This test evaluates ammonium levels in plant leaves, providing valuable insights to optimize fertilizer applications and avoid nutrient imbalances.

Why is Ammonium Important?

  • Essential for Growth: Ammonium is a preferred nitrogen-containing nutrient for many plants.
  • Natural Conversion Process: Ammonium can be converted by bacteria into nitrite (NO2) and nitrate (NO3), which are then used by plants.
  • Balance is Key: At low levels, ammonium promotes healthy plant growth. However, excessive levels can cause toxicity and harm plants.

When to Perform This Test:

  • Early in the Growing Season: Use this test to guide initial fertilizer applications and ensure optimal nitrogen levels.
  • Any Growth Stage: Evaluate ammonium levels throughout the growing cycle to monitor nutrient uptake and adjust fertilizer strategies.

Sample Submission:

  • Sample Size Requirements: Collect 10 to 15 of the most recent fully expanded leaves.
  • Packaging: Ship samples in a paper bag to prevent moisture damage during transit.
  • Turnaround Time: Results available within 24 to 48 hours.

Benefits of Ammonium Analysis:

  • Optimize Fertilizer Use: Avoid over- or under-application of nitrogen.
  • Prevent Toxicity: Maintain healthy ammonium levels to support plant growth.
  • Tailored Nutrient Management: Adjust fertilizer strategies based on accurate ammonium data.
