This month from ScienceWatch.com, we have
listed our ranking in Agricultural Sciences by
citations per paper—among countries that
collected 10,000 or more citations during the
period—to reveal weighted impact. Read more
below.

The data above were extracted from the
Essential Science IndicatorsSM database from
Clarivate.
This database, currently covering the period January 1999 through April
30, 2009, surveys only journal articles (original research reports and
review articles) indexed by Clarivate. Articles are assigned to a
category based on the journals in which they were published and Thomson
Reuters’s journal-to-category field definition scheme. Both
articles tabulated and citation counts to those articles are for the
period indicated.
Here our ranking in Agricultural Sciences is by citations per
paper—among nations that collected 10,000 or more citations
during the period—to reveal weighted impact. For articles with
multiple authors from different nations, each nation receives full, not
fractional, citation credit. Essential Science Indicators
lists nations ranked in the top 50% for a field over a given period,
based on total citations. In Agricultural Sciences, 98 nations are
listed, meaning 196 were surveyed. 30 nations collected at least 10,000
citations during the period. The average citation rate for field of
Agricultural Sciences is 6.10.
