From the preface The introductory course in general quantitative analysis in Part I deals with a select list of such analytical processes as may be considered useful for impressing upon the mind of the student the principles of analytical work as well as the importance of exercising intelligence and care in all work of the laboratory. Bearing in mind the fact that in most college curricula this first course must necessarily be brief the typical classes of methods for a given determination have been treated together. This in turn has involved a preliminary discussion of materials and methods of both gravimetric and volumetric analysis. Part II dealing with certain special measurements has been included in recognition of the fact that the highly important instruments and methods there discussed are too seldom understood by the chemists who use them in industrial work. In our own classes we have found lectures upon the theoretical principles underlying the construction and use of these forms of apparatus to be of very great value. In part III is included a treatment of the six classes of materials most often considered in courses in agricultural analysis and probably of interest to the greatest number of agricultural chemists. The significance of the results of the analyses in connection with agricultural problems has been given as much attention as was thought possible without going outside the proper scope of a book of this character. This it is believed will add an interest to the laboratory work and supply a certain motivation otherwise largely lacking. 330 pp.

Buch. Condición: Neu. Neuware - 'Quantitative Agricultural Analysis' provides a detailed exploration of the methods used to evaluate materials essential to the agricultural sciences. Written by Edward G. Mahiin and Ralph H. Carr, this comprehensive work serves as a foundational text for students and professionals in the fields of agronomy and agricultural chemistry. The book covers the quantitative determination of chemical components in soils, fertilizers, feeds, and dairy products, emphasizing precision in laboratory techniques.The authors offer systematic procedures for the analysis of both organic and inorganic substances, bridging the gap between theoretical chemistry and practical farming applications. By focusing on the scientific measurement of essential agricultural elements, the work provides crucial insights into the composition of materials that drive productivity and soil health. This volume remains a significant resource for those interested in the historical development of agricultural science and the rigorous methodologies that underpin soil and crop management. It is an indispensable reference for understanding the analytical standards applied to the study of agriculture during a pivotal era of scientific advancement in the early twentieth century.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
