A Practical Treatise on Pure Fertilizers; and the Chemical Conversion of Rock Guanos, Marlstones, Coprolites, and the Crude Phosphates of Lime and Alu (Paperback) (ISBN-13: 9781172165919)

"A Practical Treatise on Pure Fertilizers" by Campbell Morfit, originally published in 1872, delves into the chemical processes involved in creating effective fertilizers. This comprehensive guide explores the conversion of raw materials such as rock guanos, marlstones, coprolites, and crude phosphates of lime and alumina into valuable agricultural products. It offers practical insights into the techniques and methodologies employed in the 19th century for enhancing soil fertility and boosting crop yields.

This treatise is a valuable resource for historians of science and agriculture, as well as anyone interested in the historical development of fertilizer production and its impact on agricultural practices. It reflects the state-of-the-art understanding of chemistry and its application to agriculture during a period of significant advancements in both fields.
