VI
Step by step development of the nutrition
recommendations by taking into account all
growth- and agrotechnical conditions
Status report can be produced at any stage and
sent to a remote location by e-mail, fax, etc.
Main features of Haifa Nutri-Net
VII
The nutrition scheme is built by stages, in
accordance with the irrigation method:
 Pre-plant application
 Side / top dressing or Nutrigation™ (fertigation)
Foliar feeding
Nutrigation means combining irrigation with the application of
pure fertilizers that contain nutrients exclusively
Main features of Haifa Nutri-Net
VII
If the nutrition program is based on Nutrigation,
application program is further specifying relevant
growth phases & days
Yet, the user can, at any stage overrule the
recommendations by his own preferences
Main features of Haifa Nutri-Net
VIII
A comprehensive irrigation program is built
in accordance with:
1. Crop-specific water requirements, further
specifying growth phases
2. Irrigation method and equipment available to the
grower
3. Structure of root zone and water retention of the
soil
4. Local agro-meteorological conditions
5. Irrigation intervals and doses
Main features of Haifa Nutri-Net
IX
A detailed nutrigation program is built in
accordance with all previously mentioned
parameters:
