ROOTGUARD®
The ultimate subsurface
irrigation system
| WHAT IS SUBSURFACE DRIP IRRIGATION ? |
Traditional drip irrigation is found
above ground, now with the
invention of ROOTGUARD¹, the lines can
be buried below
ground for a long, trouble-free life. Subsurface
irrigation allows
the precise application of water, nutrients and other
agro-
chemicals directly to the root zone of plants. This
allows the
farmer to optimize the growing environment and leads to
higher
quality and quantity crop yields. By stressing product
quality,
dependability and ease of use, Geoflow is providing the
best
products available in the Subsurface irrigation market
today. |

The depth and placement of subsurface
driplines is determined
by the soil composition and the crop needs. An efficient
installation has water moving by capillary action at a
depth of
4 to 30 inches beneath the surface, forming a continuous
wetted
area along the plant rows.
Frequent irrigation cycles (several times daily) maximize
capilllary
action and minimize water surfacing.

Given the same amount of water,
subsurface drip irrigation covers a 46%
larger wetted colume 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.² |

| WHY USE SUBSURFACE DRIP IRRIGATION ? |
 | Higher Yields
Water and nutrients delivered directly to the
root zone promote
healthy plant growth and reduce plant stress. |
| Healthier, Better Quality Crops
Soil and foilage are kept dry, reducing
fungal diseases caused
by surface or overhead irrigation. Eliminates
fruit and vegetable
spotting commonly caused by overhead irrigation. |
| Safe and Efficient Delievery of
Fertilizers & Insecticides
Chemicals are directly applied to the
roots with subsurface drip,
reducing chemical pollution from leaching into
the aquifer. |
| Fewer Weeds
A dry soil surface reduces germination. |
| Improved Soil Aeration
Fine soil particles are not washed down,
decreasing soil
compaction and improving root growth. |
| Dry Soil Surface
With a dry soil surface, cultural
operations and harvest can take
place while the system is operating. |
| Substantial Water Saving
Water loss due to evaporation, mist,
surface runoff or wind
interference is eliminated. |
|
| Less Salts
Less water also means less salts in the
soil or the aquifer. |
| A Longer or Extended Irrigation System
Life
The turbulent flow drip emitters and
tubing are made with
durable polymers. When placed underground the
irrigation
system is protected from damage caused by
ultraviolet light,
temperature fluctuations and damage due to
cultural operations.
Plus ROOTGUARD deters clogging. |
| Less Animal, Human or Mechanical Damage
No sprinkler heads, pipes or surface
driplines that can cause
injury, or be subjected to damage by vandalism,
animals or
harvest activities in the field. |
| Lower Maintenance Cost
The system is installed permanently
below cultivation depth,
and requires no handling. |
| Fewer Chemicals
Fungicides and insecticides are not
washed off by irrigation
water and direct delivery through the system
reduces waste. |
| Labor Savings
Easier fertilizer application, less weed
and disease control and
less maintenance means less handling. |
