Baris 1: '''Edafologi''' (dipinjam dari [[bahasa Inggris]]: ''edaphology'', yang membentuknya dari dua kata [[bahasa Yunani]] {{lang\|grc\|ἔδαφος}}, ''edaphos'', "tanah, pijakan"; dan {{lang\|grc\|-λογία}}, ''[[-logy\|-logia]]'', "lambang", "pengetahuan"), atau '''ilmu kesuburan tanah''', adalah salah satu dari dua cabang utama [[ilmu tanah]] yang mempelajari peran [[tanah]] sebagai pendukung kehidupan, terutama [[tumbuhan]]<ref>Page 8 ''in'' {{Cite book \| last = Buckman \| first = Harry O. \| last2 = Brady \| first2 = Nyle C. \| title = The Nature and Property of Soils - A College Text of Edaphology \| place = New York \| publisher = The MacMillan Company \| year = 1960 \| edition = 6th}}</ref><ref>{{cite web\|url= http://jan.ucc.nau.edu/~doetqp-p/courses/env320/lec1/Lec1.html\|title= Lecture 1 Chapter 1 Why Study Soils?\|accessdate= 2008-01-12\|last= Gardiner\|first= Duane T\|work= ENV320: Soil Science Lecture Notes\|publisher= Texas A&M University-Kingsville}}</ref>. Cabang utama ilmu tanah yang lain adalah [[pedologi]]. Baris 6: Edafologi dalam pertanian dikenal pula di beberapa tempat di dunia sebagai [[agrologi]]. Edafologi juga dipelajari oleh [[ilmu lingkungan]] sebagai [[ilmu tanah lingkungan]]. Di Rusia edafologi dianggap sama dengan [[pedologi]], namun dengan sisi terapan yang kuat di bidang [[fisika]] dan [[kimia]] pertanian.<ref>{{cite journal \| last = Tseits \| first = M.

Xenophon telah mencatat manfaat pemendaman [[tanaman penutup tanah]] (''cover crop'') terhadap hasil pertanaman. Cato, dengan karyanya ''[[De Agri Cultura]]'' ("On Farming"), telah menyarankan pengolahan tanah, dan rotasi tanaman (termasuk penggunaan legum dalam salah satu tahap rotasi). Ia di sana juga telah memberikan panduan jenis-jenis tanah yang sesuai dengan tanaman tertentu untuk mendukung pertanaman yang baik. <!-- [[Jan Baptist van Helmont]] (~~1577–1644~~1577–1644) performed a famous experiment, growing a willow tree in a pot of soil and supplying only rainwater for five years. The weight gained by the tree was greater than the weight loss of the soil. He concluded that the willow was made of water. Although only partly correct, his experiment reignited interest in edaphology.<ref>Xenophon, Cato and Van Helmont: see page 9-12 ''in'' {{Cite book \| last = Miller \| first = Raymond W. \| last2 = Gardiner \| first2 = Duane T. \| title = Soils in Our Environment \| place = Upper Saddle River, NJ 07458 \| publisher = Prentice Hall \| year = 1998 \| edition = 8th \| isbn = 0136108822}}</ref> --> <!-- ==Areas of study== Baris 23: {{main\|Environmental soil science}} Environmental soil science studies our interaction with the [[pedosphere]] on beyond crop production.
