Synopsis
Excerpt from Methods in Soil Analysis: Technical Bulletin Much importance has been attributed in recent years to the analysis of soils for total constituents. The literature covering the methods for such analysis, while rather extensive, is scattered, and in many cases the methods described are not well suited to rapid routine practice. In view of these facts it has been thought that the compilation and publication of the methods used and in part evolved in the soils laboratory of the West Virginia Agricultural Experiment Station may be of value to others desiring methods which arc rapid and at the same time sufficiently accurate to meet the requirements of most soil investigations. The methods arc presented in sufficient detail to permit their employment by those who have not had extensive experience in quantitative work. In the development of these methods access has been had to the methods employed by the New York, Illinois, and Wisconsin experiment stations. Use has also been made of material from procedures as published by the Ohio, Tennessee, and other experiment stations. Much has been adapted from bulletin 422 of the United States Geological Survey. Most of the methods herein described have been proved reliable by their successful use in several hundred analyses of various types of West Virginia soils.In sampling any given area three composite samples are ordinarily chosen, representing different depths as follows: sample A, 0 to 62/3 inches; sample B, 62/3 to 20 inches; sample C, 20 to 40 inches. A one-inch soil auger is used in securing samples. Sample A is a composite of from 20 to 30 borings, so chosen as to furnish as nearly as possible a truly representative sample of the area in question. Samples B and C arc composites of from 10 to 15 borings. As samples are taken in the field they arc placed in clean cloth sacks and sent immediately to the laboratory where they are air dried and prepared for analysis.

Methods in Soil Analysis: Technical Bulletin (Classic Reprint)
Print on DemandSeller: Forgotten Books, London, United Kingdom
Seller rating 5 out of 5 stars
Paperback. Condition: New. Print on Demand. This book provides a detailed look at basic methods used in soil analysis. It was initially written to assemble the techniques used and developed in the soil laboratory of the West Virginia Agricultural Experiment Station. The methods are presented in sufficient detail to permit their employment by those who have not had extensive experience in quantitative work. The book covers determining iron, aluminum, titanium, manganese, calcium, magnesium, potassium, phosphorus, total nitrogen, total carbon, total sulfur, silica, carbonate carbon, lime requirement, nitrate nitrogen, and ammonium nitrogen. The author emphasizes eliminating difficulties encountered when determining silica in the same sample as the other elements, which has proven particularly advantageous in the West Virginia Experiment Station laboratory. The methods outlined depend on the decomposition of the sample by means of hydrofluoric acid and are open to possible objections. However, the subsequent procedure permits appropriate corrections. This book will be of value to those interested in developing and refining soil analysis techniques. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
