Perhaps you should try some spelling variations:
irrigation requirements » irrigation equipment, nutrition requirements
requirements timed » requirements based, requirements come, requirements tpm2
timed dimensional » mixed dimensional, fixed dimensional, three dimensional
array from » arrays from, gray from, ray from
rays » days, ray, ways

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

• Performing a fuzzy search may retrieve terms with similar spellings: irrigation requirements timed dimensional ((((array from) or (array from))) or (rays from))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: irrigation requirements timed dimensional ((((array from) OR (array from))) OR (rays from)).
• Adding a wildcard symbol may retrieve word variants: irrigation requirements timed dimensional ((((array from) or (array from))) or (rays from))*.
