Paperback. Condición: New. Print on Demand. This book delves into the composition of gases found in swampy rice fields, particularly methane and hydrogen, and how they relate to the growth and cultivation of rice in these unique environments. In the past, it was assumed that certain fermentation processes specific to rice fields were responsible for the production of these gases. However, this book presents evidence to challenge this notion, suggesting instead that the gases are formed through a series of reactions involving the decomposition of organic matter under anaerobic conditions. The author delves into the details of these reactions and their implications for the cultivation and management of rice paddies, providing valuable insights for researchers, agricultural scientists, and policymakers working in the field. 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. Condición: New. Print on Demand. This book explores the complex interactions between swamp rice soils and their gaseous environment. The author offers compelling evidence that a significant portion of the nitrogen gas found in these soils originates from the decomposition of organic matter, primarily from green manure and soil organic matter, and to a lesser extent from the decay of the crop's own roots. The author also demonstrates that the crop's influence on the soil's physical properties, particularly the formation of a surface layer that impedes gas exchange, plays a crucial role in the accumulation and composition of soil gases. The author's findings challenge the conventional view that green manures directly benefit the crop by providing nitrogen and instead highlights their indirect effects on soil aeration and nutrient availability. This book provides valuable insights into the complex interactions within swamp rice soils, offering a foundation for optimizing agricultural practices and improving crop yields.
