All sorts of dung and compost contain some matter which, when mixed with the soil, ferments therein; and by such ferment dissolves, crumbles, and divides the earth very much. This is the chief and almost only use of dung. … This proves, that its (manure) use is not to nourish, but to dissolve, i.e., divide the terrestrial matter, which affords nourishment to the Mouths of vegetable roots.
— Jethro Tull
His underestimate of the value of manure. In The Horse-Hoeing Husbandry (1733), 18.

I might, as a Rustick, omit the Ceremony of a Preface, were it not reasonable to expect, that an Apology will be required for writing and publishing a Book without the usual Qualifications of an Author. … I was so far from being inclined to the Scribbling Disease, that I had disused Writing for above twenty Years, before I was prevail’d on to commit my Thoughts upon Husbandry, and the Descriptions of my Engines to Paper.

Leaves are the Parts, or Bowels of a Plant, which perform the same Office to Sap, as the Lungs of an Animal do to Blood; that is, they purify or cleanse it of the Recrements, or fuliginous Steams, received in the Circulation, being the unfit Parts of the Food; and perhaps some decay’d Particles, which fly off the Vessels, thro’ which Blood and Sap do pass respectively. Besides which Use, the Nitro-aerious Particles may there enter, to keep up the vital Ferment or Flame.

Quotes by others about Jethro Tull (1)

[Jethro Tull] was the first Englishman—perhaps the first writer, ancient and modern—who has attempted, with any tolerable degree of success, to reduce the art of agriculture to certain and uniform principles; and it must be acknowledged that he has done more towards establishing a rational and practical method of husbandry than all the writers who have gone before him.
In Letter (18 Oct 1764), signed only “D.Y.” from Hungerford, in Sylvanus Urban (ed.), 'Observations on the late Improvements in Agriculture', The Gentleman’s Magazine (Nov 1764), 525.

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
