Paperback. Condición: 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.

Paperback. Condición: New. Print on Demand. This book examines the long-term impact of fertilizers on soil composition, crop yield, and the effectiveness of various treatments over 15 years. The author analyzed soil samples from a series of test plots that had received different combinations of fertilizers, including nitrogen, phosphorus, potassium, and lime, and compared them to untreated control plots. The results demonstrate that nitrogen fixation occurred in plots treated with acid phosphate and/or sulfate of potash, with rates varying from 20 to 78 pounds per acre per year. Notably, phosphorus applied to the soil remained fixed in the top 6 3/4 inches, indicating that it was not lost through drainage. Furthermore, the use of fertilizers, particularly complete fertilizers and manure, led to increased organic matter content and decreased soil acidity. In contrast, excessive lime application was found to deplete nitrogen, phosphorus, and organic matter. These findings suggest that judicious fertilizer use can enhance soil health, promote crop growth, and potentially reduce the need for lime in acidic soils. This book offers valuable insights for farmers, soil scientists, and anyone interested in sustainable agricultural practices and soil management strategies.
