DripIn®with ROOTGUARD
The ROOTGUARD®Advantage
• Higher Yields
Water and nutrients delivered directly to the
root zone at regular short intervals, promote
healthy plant growth and reduce stress.
• Substantial Water Savings
Improved irrigation system efficiency, combined
with the ability to schedule short and frequent
irrigation run time rates eliminate run-off as
well as deep percolation.
®
• Healthier, Better Quality Crops
Soil surface and foliage is kept dry, reducing
fungal diseases caused by moisture on the soil
surface and resulting high humidity in the
canopy.
• Further Water Savings
Water loss due to evaporation is eliminated.
As less water is applied overall, so is less salts,
found in the water, applied.
• Improved Soil Aeration
Fine soil particles are not washed down,
decreasing soil compaction and thus improving
root growth.
• Fewer Chemicals
Large volumes of irrigation water do not wash
fungicides, insecticides and herbicides away.
• Fewer Weeds
A dry soil surface reduces germination.
More ROOTGUARD®Advantage:
• Longer Irrigation System Life
The Drip In emitters and tubing are made with
durable polymers. When placed underground the
system is protected from damaging ultra violet
rays and temperature fluctuations. The lack of
evaporation around the subsurface dripper also
eliminates any chemical build-up such as bicarbonates. It has been noted that Drip In with
ROOTGUARD
associated with bacterial slime build up in the
drip emitter. The absence of light at the drip
emitter outlet orifice also eliminated any
possibility of algae growth in the last section of
the dripper flow-path. The system is a solid set
subsurface system that eliminates any irrigation
handling and subsequent damages.
• Safe and Efficient Delivery of Fertilizer
& Insecticides
Chemicals are directly applied to the roots with
subsurface drip reducing possibilities of surface
contact
• Less Animal, Human and Mechanical Damage
No surface risers or drip lines that can cause
injury, or be subject to damage by operators
during cultural and harvest practices or animals
such as coyotes.
• Labor Savings
Less weed and disease control as well as less
maintenance means proportionally less labor.
• Larger Soil Volume Irrigated
Given that water is conveyed in soil through
capillary action as well as gravity, the subsurface
drip emitter allows water to also move upward in
all directions, resulting in a volume up to 46%
larger to be irrigated.
• Dry Soil Surface
With a dry soil surface, all cultural and harvest
practices can take place irrespective of irrigation
scheduling.

Subsurface Drip Irrigation
With traditional drip irrigation, the drip tubing
and drip emitters are installed above ground. In the
infancy of drip irrigation (30 years ago), given the
style and quality of equipment used, this was a wise
choice. Today, with the new generation style
turbulent drippers, (both pressure compensating
and non-compensating) accepted filtration
standards and maintenance schedules, most of the
fears of emitter clogging have disappeared. The
only remaining barrier against long term,
successful, subsurface drip irrigation system has
been root intrusion.

ROOTGUARD
Drip In ROOTGUARD®is the key to subsurface
drip irrigation success. ROOTGUARD technology
combines Treflan
root growth. This is patented technology by
Geoflow, Inc. where the herbicide is released at a
uniform rate over a long period of time. It maintains
a sufficient concentration in the soil immediately
surrounding the drip emitter, to prevent
longitudinal rootgrowth into the dripper. Built-in
ROOTGUARD protection is guaranteed for 10 years
by Geoflow, Inc. to prevent roots from growing into
these impregnated subsurface drip emitters.

Surface dripSubsurface drip
Given the same amount of water, Subsurface Drip Irrigation Covers a 46% larger wetted volume of soil than
a surface drip system. This decreases the saturation point of the soil, which not only leaves room for more air,
but also improves the capillary movement of water and decreases the water lost to deep percolation.

System Engineering Practices
Subsurface drip irrigation systems use the same basic components as surface drip irrigation systems. This
includes water filtration and treatment, fertilizer and chemical injection, air vents for both air and vacuum
relief, flush valves and manual or automatic control. In addition to the above all ROOTGUARD®subsurface
systems need to be equipped with vacuum relief on all drip lines at the high points (elevation) to avert dripper
clogging from ingesting soil particulate during system shut down.
Any organic fertilizers, soil additives and/or water treatments injected through Drip In with Rootguard is not
recommended and will void the warranty."

Drip In Dripline Advantages:
The In-line Emitter
is a labyrinth type, turbulent flow dripper. The
emitter is enclosed and inseparably welded to
the inside wall of the tubing as it is extruded
in the manufacturing process. This emitter has
enjoyed over 25 years of reliable performance
in a variety of applications.
