‎---- EDITION ORIGINALE ---- BEL EXEMPLAIRE ---- "LE PERE DE L'AGRONOMIE ET DE LA CHMIE AGRICOLE - LE PLUS GRAND AGRONOME DU XIXe SIECLE" ---- "BOUSSINGAULT applied organic analysis in field and laboratory research to problems of soil fertility, crop rotation, plant and soil fixation of nitrogen, ammnonia in rainwater, and nitrification in order to détermine the sources of plant nitrogen. He suggested that legumes may fix nitrogen from atmospheric sources. He 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 satify the nitrogen needs of plants. He studied the proportions of organic materials that pass through plants and animals. 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. He studied the chemistry of nitrification, identifying fertile soil as a prerequisite. His experiments on nitrogen fixation and his work on nitrification brought the problem of plant nitrogen essentially to the threshold of its modern microbiological formulation". (DSB II pp. 356/357) ---- "La plus importante contribution en physiologie végétale vint de celui qui fut sans doute LE PLUS GRAND AGRONOME DU XIXe SIECLE, J.B. BOUSSINGAULT (1802/1187). D'origine modeste, il suit les cours de l'Ecole des mines de Saint-Etienne, puis il dirige l'exploitation d'une mine à la Nouvelle-Grenade. Attaché à l'état-major de Bolivar lors de l'insurrection des colonies espagnoles, il rapporte de ses compagnes des observations géologiques et météorologiques. Rentré en France, il obtient la chaire de chimie à la faculté des sciences de Lyon, puis, en 1829, celle d'agriculture au Conservatoire des arts et métiers. En 1837, il succède à Thénard à la Sorbonne ; en 1839, il entre à l'Académie des sciences. Il fonde l'Institut National Agronomique. Boussingault s'illustra par tant de travaux qu'il mérite le nom de "PERE DE L'AGRONOMIE ET DE LA CHIMIE AGRICOLE". (Davy De Virville "Histoire de la botanique en France" pp. 155 & 269 et Larousse "Inventeurs & Scientifiques") ---- Partington IV p. 341 ---- Phénomènes physiques de la végétation - De la constitution chimique des végétaux - De la fermentation vineuse - Des sols - Des engrais - Des engrais minéraux ou amendements - Des assolements - De l'alimentation des animaux - De l'économie des animaux annexés à l'industrie agricole ; de la production animale et de la relation avec la formation des engrais - Considérations météorologiques**8210(821)/o2+823/MAIS‎
