Principles and practice of agricultural analysis. Volume 1 (of 3), Soils

This volume serves as a practical guide for anyone tasked with examining soils, from classroom instructors to field analysts. It opens with clear definitions of soil components, the chemistry of minerals, and the processes that turn rock into fertile earth. The author draws on worldwide experience, especially North American observations, to present a balanced foundation for further study.

The middle sections walk readers through the art of collecting representative samples, comparing classic techniques such as Hilgard’s and the Royal Agricultural Society’s methods. Detailed instructions on laboratory preparation make the transition from field to bench straightforward, while discussions of moisture, permeability, and bulk handling prepare users for real‑world challenges.

The final chapters explore the physical behavior of soils, explaining color, specific gravity, heat conductivity, cohesion, and porosity. By linking these properties to practical measurements—thermometry, absorption tests, and capillary action—the book equips students and professionals with the tools needed to assess soil health and suitability for cultivation.
