Paperback. Etat : New. Print on Demand. This book examines the chemical and physical absorption of lime by soils, a crucial soil property that affects nutrient availability and plant growth. The author begins by discussing previous research on the subject, which focused on the effects of neutral salts and lime on soils. The author suggests that these studies indicate that the displacement of bases in the soil occurs in practically theoretical chemical proportions. The author then presents their own research on the absorption of lime by soils. They used calcium bicarbonate solutions containing varying amounts of carbonic acid to treat soils and measured the amount of lime absorbed. Their results show that, within the ranges of concentration tested, the action of ammonium chloride on soil follows the law of mass action and must therefore be considered a purely chemical reaction. The acidity developed when certain soils are treated with neutral salts may be explained as an adsorption phenomenon because the equilibrium follows the usual adsorption isotherm. The acidity has, however, been traced generally to the presence of aluminium salts in solution, and their presence suggests a more fundamental change than purely physical adsorption. This book contributes to our understanding of soil chemistry and provides valuable insights for researchers and practitioners in agriculture and soil science.

Paperback. Etat : New. Print on Demand. Interested in discovering the secrets to the production of a poison capable of causing great suffering, the author of this book delves into the world of plants and seeds to explore the existence of hydrocyanic acid in nature. Through the examination of different plant parts and the testing of seeds from various sources, the author uncovers the connection between the presence of hydrocyanic acid and the stages of plant development and storage conditions. What emerges is a detailed analysis of enzyme activity, along with its effects on the production and breakdown of hydrocyanic acid in plants. This book is a valuable resource for scientists and researchers seeking to deepen their understanding of plant chemistry, enzyme activity, and the production of natural toxins.

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.
