Taschenbuch. Condition: Neu. Neuware - Stephenson's seminal study of soil acidity and bacterial activity revolutionized our understanding of the relationship between soil health and agricultural productivity.

Paperback. Condition: New. Print on Demand. This book presents a study on the decrease of soil acidity as organic matter is introduced to the samples. The author delves into the bacteriological changes that occur with the addition of organic materials such as soybean, rape, straw and blood, and how in most cases the organic treatment has reduced the lime requirement of the soil. There is also a focus on the hydrogen ion concentration caused by the addition of organic matter. The author concludes that the organic acids produced by the decay of organic matter do not accumulate in soils under favourable conditions for crop production. These insights are significant because they contribute to the understanding of soil acidity and how it can be managed through organic matter application. 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.…
