Ridges and Furrows

This self-paced learning module explores the essential role of ridges and furrows within the Integrated Aqua-Vegeculture System (iAVs). Through guided reading from the iAVs Handbook and interactive quizzes, participants will gain practical knowledge of their design, function, and benefits.

Key topics include:

  • Purpose and Function of Ridges and Furrows
  • How furrows direct nutrient-rich water to plant roots.
  • The role of furrows in improving water distribution and nutrient delivery.
  • How ridges prevent waterlogging, enhance aeration, and reduce risks of root rot.
  • The nutrient gradient in the sand bed, with higher concentrations near furrows.
  • How furrows achieve targeted irrigation and maximize nutrient uptake.
  • The impact of ridges on air circulation and irrigation efficiency.
  • Recommended dimensions for furrows, including depth, width, and layout.
  • How to adapt furrow and ridge design for different crops and spacing needs.
  • The importance of maintaining correct furrow depth relative to the flood level.
  • The “edge effect” created by ridges and furrows, promoting diverse conditions for plants and microbes.
  • How ridges and furrows facilitate root interaction, microbial activity, and environmental stability.
  • The micro-environments introduced by varied topography and their impact on plant growth.
  • How to create furrows with a level top sand surface.
  • How to ensure ridges remain above the flood line to maintain system integrity.
  • How ridges provide stability for plants and better resource allocation for growth.
