Surface Moisture Evaporation
and
Irrigation Run-Time Factor
Understanding Soil Surface Evaporation
is the beginning to reducing
Landscape Water Waste
Often irrigation run-time is too short
So, the frequency of irrigation days
is too high!

Whenever run-times don't match soil composition
Irrigation moisture is at the suface!
Therefore Evaporation Waste is High




Plant Health Requires

Moisture present
throughout the Root Zone
Deep Moisture equates to less frequent irrigations
Longer INTERVALS between irrigations saves water!




Deep Moisture is Insulated
from Temperature
and other Evaporative factors

Between 20 and 30 cm
(8 and 12 inches)
Soil moisture transfer is greatly slowed



Insulation from surface temperature
is primary in response for
reduced transfer and evaporation
Deep moisture happens naturally
in regions with lots of rainfall.

Drought prone areas must rely on irrigation water.
When that water does not penetrate deeply enough;
The result is rapid evaporation and shallow roots

This creates plant stress
Irrigation frequencies are then typicaqlly increased.
Resulting in plants exposed to shallow roots & drought

Ignoring the option of Deep Irrigations!

surface moisture = evaporation = WASTE!



Whereas
Matching the irrigation feed rate
and run-time to the
Soil Composition
much healthier plants
while saving water waste and expense

Less frequent irrigations
Deeper Moisture permeation
