APPLICATION
OF CHEMICALS BY MICRO-IRRIGATION
Benefits of this technology
- Delivers plant nutrients directly into
the wetted zone (where root
development is intensive).
- Uniform application of fertilizers.
- Higher crop yields due to precise
application of fertilizer
- Reduce soil compaction because less
equipment runs in the field
- Reduced crop damage because less
equipment runs in the field
- Labor machinery and fuel savings.
- Can be used with a large variety of
chemicals.
METHODS OF
CHEMICAL APPLICATION IN MICRO-IRRIGATION
- Differential pressure tanks.
- Injection pumps.
- Venturi devices. Simple and low cost
systems. They do not require an external power source; but
they generate a significant head loss which tend to limit their
use to small to medium irrigation systems.
Some
Definitions
A venturi is a device which
creates vacuum when fluid flows through it. The fluid which creates
the vacuum is known as the motive fluid. The motive fluid for
irrigation injectors is the irrigation water itself. Vacuum created
by the venturi sucks fertilizer or chemical into the motive water.
How a Venturi
works
Our Venturi are water driven, ie
they are driven by the pressure of the main irrigation pipeline. The
energy to run these devices reduces the irrigation water pressure of
the water line.
What to
inject with a Venturi
-
liquid fertilizers (Nitrogen, Potassium,
Phosphorus, etc...)
-
pesticide injection,
-
acid injection, for example to unblock
dripper or distribution orifices.
