Samuel William Johnson (chemist) Samuel William Johnson (July 3, 1830 – July 21, 1909) was an American agricultural chemistry agricultural chemist. He was elected in 1866 to the U.S. National Academy of Sciences and for the academic year 1878–1879 served as president of the American Chemical Society. Quotes Agricultural science, in its widest scope, comprehends a vast range of subjects. It includes something from nearly every department of human learning.The natural sciences of geology, meteorology, mechanics, physics, chemistry, botany, zoology and physiology, are most intimately related to it. It is not less concerned with Social economy social and political economy, with commerce and law. 1868 How crops grow: a treatise on the chemical composition, structure, and life of the plant, for all students of agriculture Orange Judd and Company New York City 9781425542344 https://books.google.com/books?id=6LkyAQAAMAAJ&pg=PA24 12010899 24 (2nd edition 1891) Georges Ville Ville has stated, 1851–2, that vegetation in Conservatory (greenhouse) conservatories may be remarkably promoted by impregnating the air with gaseous Ammonium carbonate carbonate of ammonia. For this purpose lumps of the solid salt are so disposed on the heating apparatus of the Greenhouse green-house as to gradually vaporize, or vessels containing a mixture of Calcium oxide quicklime and Salammoniac sal ammoniac may be employed. Care must be taken that the air does not contain at any time more than four ten-thousandths of its weight of the salt; otherwise the foliage of tender plants is injured. Like results were obtained by Alexander Petzholdt Petzholdt de and Chlebodarow in 1852–3. 1870 How crops feed: a treatise on the atmosphere and soil as related to the nutrition of agricultural plants Orange Judd and Company New York City https://books.google.com/books?id=tZREAAAAIAAJ&pg=PA56 12012383 56 Quotes about Samuel William Johnson For more than fifty years he was a constant contributor to agricultural and scientific journals. Although his publications were numerous he wrote few books. Two of these, however, were very successful, namely, "How Crops Grow," published in 1868, and "How Crops Feed," published in 1870. These books were the first printed in this country which brought together the data scattered through the literature relating to the composition and Plant physiology physiology of plants. They furnished a new basis for instruction in agriculture and were more widely read than any books before published on agricultural chemistry. They were translated into German, Russian, Swedish, and Japanese, and the former into Italian and French also.
