Water & Nutrient Management:
On-Farm Blue Dye Demonstrations
Improving irrigation management in vegetable crop production reduces production costs, saves water, and reduces the risk of nutrient leaching. As water movement in the root zone below mulched beds is difficult to see, injecting soluble dye through the drip irrigation system provides a simple and practical method to visualize water movement in the soil.
These three modules provide insight into the blue dye injection process:
