It is well-known that humic acid plays an irreplaceable role in agriculture, especially for soil improvement. Humic acid in the improvement of soil structure, reduce soil bulk density, soil pH adjustment and many other aspects have a significant effect. In order to make readers understand more about the role of humic acid in soil improvement, this column is based on the database of “CNKI” and retrieved nearly 30 years (1979-2008) published in “Humic Acid” magazine, And those published in non-humic acid for the last 10 years (1999-2008), with titles such as “humic acid, humic acid, fulvic acid, black Humic acid, humic acid, humin, fulvic acid, humus) + soil improvement ”key words for processing, a total of 106 articles. Among them, “Humic Acid” magazine published 46 articles; “Humic Acid” magazine published 60 articles. This column will be published in the Humic Acid Magazine 1979-2008 this literature, with the title, author, year of publication and the period of 4 elements edited and published; the 1999-2008 “humic acid” magazine published in this category Literature, with the title, the first author, publication, publication year and the period of 5 elements editor.
