This self-paced learning module provides a foundational understanding of the crucial role of pH in the Integrated Aqua-Vegeculture System (iAVs). Through guided reading from the iAVs Handbook and an interactive quiz, you’ll explore how to maintain optimal pH levels to support the health of fish, plants, and beneficial microbes—all of which are essential for a productive iAVs.

In this module, you will cover key aspects of pH management within iAVs, including:

  • The importance of pH in maintaining a balanced ecosystem for plants, fish, and microbes.
  • How pH affects nutrient availability in the system.
  • The ideal pH range for iAVs (6.4 ± 0.4).
  • The relationship between pH and soil microbiology, including how a balanced pH promotes microbial activity.
  • How pH impacts plant growth, including nutrient uptake and overall health.
  • Priorities for managing pH in iAVs, focusing first on soil microbiology, then plants, and finally fish.
  • pH tolerance levels for many fish species used in aquaculture.
  • The importance of avoiding extreme pH levels to protect both fish and beneficial microorganisms.
  • How to monitor pH using a reliable digital pH meter or test kit.
  • How to track pH trends over time by recording pH measurements at least weekly, or more frequently in new or unstable systems.
  • The importance of testing and adjusting source water pH before introducing it to the system.

By completing this module, you’ll gain a clear understanding of how pH functions within the iAVs ecosystem and learn practical methods to maintain a stable and productive system.
