Specify a domain:

After entering search terms in Google, try specifying a domain where you'd like to limit your search. Adding "" to your search (without the quotes), for instance, will limit your search to sites in the .gov domain. Adding "" will only find results on the USDA site.

Include subject keywords and site keywords:

Searching for "sorghum nutrient deficiency" is a good first step. Adding "horticulture" or "cooperative extension" or "fact sheet" will also help.
