Jethro Tull: His Influence on Mechanized Agriculture (Great Innovators), by G. E. Fussell

Eighteenth-century British gentleman farmer Jethro Tull (1674-1741) is popularly regarded as the inventor of the seed drill, widely cited by agricultural historians, soil scientists and school history textbooks alike. Whether Tull was in fact the first to experiment with a mechanical seed drill and the horse-drawn cultivators drilling made possible is doubtful, but he did do much to make their acceptance in the long run more widespread. What is less well known is that Tull's mechanical innovations were accompanied by a theory of plant nutrition-and a social agenda-that were equally important to the adoption of the new machines. Although he came to be celebrated by later generations, Tull's work attracted fierce critics in his own day and immediately after, not least because he categorically rejected the value of manures in maintaining soil fertility. Instead, he proposed a mechanistic theory of plant nutrition in which the stirring of the soil with the cultivator could substitute for the processes of decomposition thought to be contributed by manures, with less labor and expense. For Tull, the drill was part of an explicit strategy to minimize reliance on an unruly labor force. He also directly challenged the idea that Virgil and other classical authorities could be of any practical use in farm management. In other words, Tull was an anti-georgic improver, and could only be reinserted into the canon of agricultural history through the efforts of later agriculturists to gloss over the objectionable parts of his work. This paper explores how, a century before Liebig, Tull's Horse-Hoeing Husbandry (1731 and later editions) sparked heated debates over a constellation of issues that are still with us today: no-till vs. tillage, net profits vs. gross yields, soil biology vs. soil chemistry, yield per acre vs. yield per unit of labor, rotation costs vs. input costs.

A strange, apologetic summary of Tull
By David Manthey
While most books about famous people are either laudatory or condemnatory, this one is completely undecided. I couldn't determine if the author himself felt this way, or was trying for balance. Tull is known for his seed-drill and horse-hoe, which are forerunners of today's havesters, plows, and other farming machinery. This book gives a strange biography, descriptions of seed drills and other implements prior to Tull's work, a brief account of Tull's book and its immediate results, and finally a description of some modern farming equipment. The whole is written in a verbose apologetic manner, as if the author is fearful that either the pro-Tull or anti-Tull contingent will attack him if he says something too plainly or too boldly.
There is useful information here, but it was a chore to find it.

I too was shocked
By A Customer
I must admit, like the reader from Bloomington, I too was shocked at the virtuosity of Jethro Tull's output. It is one thing to be an original classic rock icon and contribute so much in that genre, but to help be responsible for a revolution in agriculture as well?
Who knew Ian Anderson was such a renaissance man?

What?
By A Customer
A lot of information here about Jethro Tull I was completely unaware of. Still, the less obscure stuff ought to have been covered too; I mean, a Jethro Tull book that doesn't even once mention "Agualung"? Come ON!
