Principles and practice of agricultural analysis. Volume 2 (of 3), Fertilizers

A thorough, hands‑on reference for anyone working with fertilizers, this volume walks the reader through the essential principles of analysis and then shows how to apply them in the laboratory. It begins with the basics of sampling both mineral and organic materials, explaining how to prepare, dry and preserve specimens so results remain reliable. The text is aimed squarely at analysts, teachers and students who need clear, step‑by‑step guidance rather than a catalogue of theory.

The core chapters cover a wide array of techniques for determining phosphoric acid and related constituents. Readers encounter both classic titration methods and more modern colorimetric approaches, with detailed instructions for citrate, molybdate and uranium procedures, as well as special treatments for basic phosphatic slags and superphosphates. Practical notes on detecting adulteration and handling complex mixtures help keep laboratory work accurate and efficient.

Although the material reflects the scientific knowledge of its time, the systematic layout and emphasis on reproducible methods give it lasting value for modern agricultural chemistry curricula and routine quality‑control work.
