Principles and practice of agricultural analysis. Volume 3 (of 3), Agricultural products

This volume guides analysts, teachers, and students through the practical chemistry of agricultural products, offering a broad‑view approach rather than a single prescribed technique. Beginning with careful sampling, drying, incineration and extraction, it details the tools and procedures needed to preserve and prepare both plant and animal materials for laboratory work. The clear step‑by‑step explanations help newcomers build confidence while still leaving room for seasoned chemists to apply their own judgment.

The second part turns to carbohydrates, presenting methods for measuring sugars and starches by density, polarized light, and classic chemical reactions. Readers discover how to operate pycnometers, set up various polariscopes, and execute copper‑based titrations with attention to temperature corrections and common sources of error. Throughout, the book balances historical insight with up‑to‑date practices, making it a reliable companion for anyone tasked with assessing the composition of crops, feeds, or other farm‑derived substances.
