Making chemistry the ‘science’ of agriculture,c. 1760–1840

Abstract

This paper sets out to capture the emergence between 1760 and 1840 of a recognizable science of agriculture in Europe. The first attempts to explain and to theorize husbandry as practiced on the farm emanated from economists and agronomists employing the ‘encyclopedic’ approach of the Enlightenment generation. Despite significant additions to chemical knowledge in the late eighteenth and the early nineteenth centuries the task of applying this knowledge to agriculture initially appeared insurmountable. Only in the 1820s and the 1830s were the obstacles gradually removed. A more rigorous approach to experimentation and to quantification evolved, and it was combined with investment in institutions seeking to educate landowners and farmers. As a result of these developments chemists secured pride-of-place above all other professionals in the management of agriculture as the primary food-producing sector of the economy.
