ARIMAD-3000
An Instrument For Measuring The Water
Potential Of Plants
General Observations:
Arimad Advantage:
ARIMAD-3000
Arimad
uses a pressure chamber of the “Schulander”
type to measure water potential of plants. This Indicates:
●
Prevailing soil moisture condition;
●
Influence of environment factors
●
State of water within the plant
Arimad
is light and portable. It can be operated easily by
one person anywhere.
Arimad
tests are simple and short. The five steps are:
●
Selecting a representative leaf;
●
Preparing the instrument;
●
Inserting pressure in the chamber;
●
Reading the plant’s water potential.
Arimad
is a plant tester in contrast to other instrument
switch test soils or climatic conditions. The pressure chamber
method demonstrates the plant’s reaction to moisture excess
or deficiency. This data will determine an exact irrigation
schedule.
The water potential imply
changes in growth, proteins
& photo synthetics.
Hence, an accurate
picture of developmental
changes within the crop is
portrayed.
changes in growth, proteins
Arimad reflects changes taking place in the
development of the plant.
Typical samples can be taken from various fields with
immediate results.
Irrigation scheduling based on Arimad enable
postponement of over irrigation and result in water
economies. A frequent check of plant’s water, which
causes a reduction in yield. The correct use of Arimad
helps to fix an exact water allocation. The growth of the
plant remains controlled from the first stage of
irrigation. A significant correlation is established
between the water potential of the plant and its yield.
An approximate indication can be given as to
recommended indications for watering cotton: Sprinkler
irrigation - 18 bar. Drip irrigation - 14 bar.
Adjustments need to be made for every crop for
different climatic conditions. If tests show a deviation
from recommended averages, a modification of the
irrigation schedule should be adapted:
High tension values - immediate application &
increasing amount of water.
Low tension values - reduction of the water application
Arimad is already widely used in different climatic
regions.
Warranty - one year (excluding damage).
Spare parts - supply guaranteed.
