Perhaps you should try some spelling variations:
fertilizer type » fertilizer use
type assessment » cycle assessment, stage assessment, trade assessment
bio fertilizer » from fertilizer, rich fertilizer, _ fertilizer
el technical » _ technical, 3 technical, 1 technical
a technical » _ technical
2 technical » _ technical

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: bio fertilizer type assessment ((((el technical) OR (a technical))) OR (2 technical)) report.~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "bio fertilizer type assessment ((((el technical) OR (a technical))) or (2 technical)) report.~".
• Adding a wildcard symbol may retrieve word variants: bio fertilizer type assessment ((((el technical) OR (a technical))) or (2 technical)) report.*.
