The data above were extracted from the Essential Science Indicators database of Thomson Reuters. This database, currently covering the period January 2000 through February 2010, surveys only journal articles (original research reports and review articles) indexed by Thomson Reuters. Articles are assigned to a category based on the journals in which they were published and the journal-to-category field-definition scheme used by Thomson Reuters. Both articles tabulated and citation counts to those articles are for the period indicated.

Here our ranking of journals in agricultural sciences is by citations per paper to reveal weighted impact. Essential Science Indicators lists journals ranked in the top 50 per cent for a field over a given period, based on total citations. In agricultural sciences, 163 journals are listed, meaning 326 journals in this field were surveyed.

Of these 163 journals, 92 published 500 or more papers during the period. This ranking of the top 20 should be recognised as distinctly different from the Thomson Reuters impact-factor rankings, which are presented in the Journal Citation Reports issued each year. The impact factor is calculated as citations in Year 3 to a journal’s contents in Years 1 and 2, divided by the number of so-called citable items (regular articles and reviews) in Years 1 and 2. Thus, the above ranking reveals longer-term impact (citations per paper).
