Paperback. Etat : New. Print on Demand. This book investigates the scant supply of phosphoric acid in Lower Burma paddy soils. It examines the problems this deficiency creates, including reduced crop yields and how it impacts the nutritional quality of the soil. The author's extensive pot culture tests yielded significant evidence to distinguish between soils with varying levels of phosphoric acid. The book's findings are particularly valuable in a region where many soils have varying levels of nutrients, making it a valuable tool for farmers and researchers seeking to optimize paddy cultivation in their regions. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Paperback. Etat : New. Print on Demand. This book details a study by the author into the absorption of soluble salts by soil and the subsequent leaching of these salts from the soil. The author examines the behavior of potassium and phosphate ions in four different types of soil. The study revealed that the concentration of soluble salts in the soil solution is largely dependent on the absorptive capacity of the individual soils. The author also found that soils continue to absorb and leach ions even after reaching a point of saturation, suggesting that the process involves both absorption and metathesis, a chemical interaction between the soil and the salts. The book's findings contribute to the understanding of soil chemistry and the factors that influence the availability of nutrients to plants. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Paperback. Etat : New. Print on Demand. This book explores how phosphate fertilizers impact Hawaiian soils, a topic of paramount significance to agriculture in the islands. The author, an expert in soil chemistry, delves into the nuanced relationship between different phosphate forms and their availability to plants, unearthing the natural limitations of the Hawaiian soil. Through meticulous experimentation, the author unveils the complex mechanisms that govern phosphate solubility and assimilation, shedding light on the factors that influence the effectiveness of phosphate fertilization. A valuable resource for farmers, researchers, and anyone seeking to optimize crop yields in Hawaii, this book provides practical guidance and deepens our understanding of soil fertility management in unique and challenging environments.
