In
the late 1970's, a new concept materialized To serve the international
farming community: fertigation. A natural step forward in agricultural
technique, fertigation (from the words fertilizer and irrigation) is an
effective method of applying chemicals and fertilizers To crops via the
existing irrigation system. The need For fertigation derives from the
fact that traditional methods of fertilization are only partially
effective and leave a lot To be desired. At the time the fertilizer is
distributed, it may be too strong For the delicate roots of the young
saplings, causing Then irreparable damage. Or on the other hand, it may
be too weak, and thus useless. Most important however, is the fact that
spread or sprayed fertilizer remains near the surface, hardly reaching
the root tips and root hairs - the points of greatest absorption.
In the process of fertigation, fertilizer is
applied directly with the irrigation water. Therefore, wherever the
water goes, the fertilizer goes with it. Fertilizer is applied only
where needed, and in the proper quantities. |
|
The obvious advantages of fertigation, therefore, are the saving of
labor and machinery, and the efficient use of the costly chemicals and
fertilizers To be applied. In fertigation, the extra activities
involved in the separate application of fertilizer are no longer
necessary; neither
is the purchase of maintenance of dedicated equipment For fertilizer
distribution. Additionally, such machinery often compresses the soil and
may cause crop damage. In conclusion, one might say that fertigation is
the most effective and least expensive way of proving nutrients To
growing field crops.

Fertilizer injector units 4-01 and 4-02
The Amiad Fertilizer and Chemical Injector units 4-01 and 4-02 require
no external power supply. Their linear hydraulic motor is powered by
the hydraulic pressure of the irrigation system. The units are supplied
with all the necessary pipes, fittings and accessories For immediate
operation. Control: The maximum injection rate of the pump is
proportional To the pressure in the main line, thus the required
injection rate is easily adjusted by throttling the injection line.
Each pulse injects 1/30 liters of chemicals - the liters of fertilizer
injected per hour = twice the number of pulses per minute. |

The Amiad TMB fertilizer pumps evenly distribute the fertilizers
throughout your irrigation system - over the whole area of the field.
The pumps inject the fertilizer solution in To the irrigation system
where it is mixed with the flowing water. When sprayed through the
sprinklers or drippers, the fertilizer will uniformly reach the roots
of all plants being irrigated. The Amiad TMB fertilizer pumps are
driven solely by the water picked up from the irrigation line itself
and can be operated anywhere in the field as long as water pressure
exceeds the minimum requirements per unit (see specifications below): |
