WHAT IS IT?
Watering plants below the soil surface
Subsurface irrigation
This part of the plant is targeted by subsurface irrigation
Roots / root zone
Name one benefit of subsurface irrigation
Saves water / fewer weeds / healthier roots
One challenge of subsurface irrigation
Hard to find leaks / clogging / expensive
Which irrigation system causes less evaporation?
Subsurface irrigation
The main goal of subsurface irrigation
To deliver water directly to plant roots / save water
Why irrigation pipes are buried underground
To reduce evaporation and deliver water directly to roots
Why subsurface irrigation uses less water than surface irrigation
Less evaporation and runoff
Why leaks are harder to find in subsurface irrigation systems
Pipes are buried underground
Which irrigation system usually causes more weeds?
Surface irrigation
One way subsurface irrigation is different from sprinklers
It waters underground / causes less evaporation / targets roots
What helps water move through the soil to reach plant roots
Soil absorption / capillary action / slow spreading through soil
How subsurface irrigation helps plants in hot climates
Water stays underground and doesn’t evaporate as quickly
What could happen if a subsurface irrigation system clogs
Plants may not get enough water / uneven watering
Which irrigation system is better for hot, dry areas and why?
Subsurface irrigation because it saves water and reduces evaporation
