(b. Paris, France, 2 February 1802; d. Paris, 11 May 1887)

agricultural chemistry.

Boussingualt’s education, although not extensive, was influenced by Thénard, Gay-Lussac, Georges Cuvier, and Haüy; he also studied engineering. His South American geological and meteorological research in 1821–1832, recommended by Alexander von Humboldt, earned him recognition as a scientist and election to the Académie des Sciences in 1839.

From 1834 to 1876, Boussingault applied organic analysis in field and laboratory research on his farm at Bechelbronn, Alsace, to problems of soil fertility, crop rotation, plant and soil fixation of nitrogen, ammonia in rainwater, and nitrification, in order to determine the sources of plant nitrogen. From 1837 to 1854 he studied the proportions of organic materials that pass through plants and animals. In his 1837–1838 fixation experiments, he suggested that legumes may fix nitrogen from atmospheric sources. Between 1838 and 1841 Boussingault showed that legumes, when grown with cereals in initially exhausted soil, will restore to soil far more nitrogen than can be attributed to fertilizers; that both herbivores and carnivores obtain their nitrogen from plants; that the nitrogen of all plants, except in the case of legumes, may be accounted for by organic fertilizer; and that rainwater does not contain enough ammonia to satisfy the nitrogen needs of plants.

Because his 1854 fixation experiments, more strictly controlled, were largely negative, Boussingault turned to soil as the prime source of plant nitrogen. In 1855–1856 he showed that Helianthus plants grow to maturity in artificial, organic-free soil when watered with nitrates. In 1859 he demonstrated the spontaneous increase of nitrates in plant-free soil and the soil fixation of nitrogen, suggesting, even though temporarily, the action of microorganisms. From 1860 to 1876 he studied the chemistry of nitrification, identifying fertile soil as a prerequisite.

Boussegualt’s experiments on nitrogen fixation from 1834 to 1854 and his work on nitrification from 1855 to 1876 brought the problem of plant nitrogen essentially to the threshold of its modern microbiological formulation.

Boussingault, Jean Baptiste Joseph Dieudonné

Jean Baptiste Joseph Dieudonné Boussingault (zhäN bätēst´ zhôzĕf´ dyödônā´ bōōsăNgō´), 1802–87, French agricultural chemist. He was professor of chemistry at Lyons and later professor of agriculture and analytical chemistry at the Paris Conservatoire des Arts et Métiers. He is known especially for his research on the nitrogen cycle. He also worked on the composition of plant tissues and on the nutritive value of forages. He is credited with the idea of agricultural field experiments. In about 1834 he laid out a series of trials on his farm in which he weighed and analyzed both the materials applied to the soil as well as the crops produced. His Économie rurale (1844) was later republished as Agronomie, chimie agricole, et physiologie (1887–91) and translated into English and German. Boussingault's experiments, however, were not limited to agriculture; his research also included work on atomic weights and the properties of steel alloys.
