Perhaps you should try some spelling variations:
irrigation requirements » irrigation equipment, nutrition requirements
requirements based » requirements a
based precision » based decision, based prediction, based decisions
array imaging » arrays imaging, airway imaging, ray imaging
array string » array strong, arrays strings, array sharing
arrays long » arrays ang, arrays load, array along

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: irrigation requirements based precision ((((arrays long) OR (array string))) OR (array imaging))~.
• Adding a wildcard symbol may retrieve word variants: irrigation requirements based precision ((((arrays long) or (array string))) or (array imaging))*.
