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.…

One fact to be kept in mind in connection with both organic acids and with bases, is that so far as available data indicate, these compounds do not remain long as such. Oxidation changes convert the nitrogen bases to nitric acid and the organic acids to carbon dioxide. Only the nitric acid produced, there fore, is capable of causing a permanent direct effect upon soil reaction. Min eral bases and acids, on the other hand, are permanently removed from the soil primarily by leaching. The portion used by the plant may be expected to be returned to the soil, at least in part.
It may be observed, too, that practical experience demonstrates that soils containing sufficient organic matter remain more productive for a longer time than those soils which are low in organic matter. Loss of organic matter is likely to result in a sour, soggy, infertile soil, which does not respond to tillage or commercial fertilizer. Muck and peat soils are notable exceptions but largely because mineral elements, such as potassium and other bases, were never present. And again, such soils occur only under those conditions which favor a large production of organic acids, and prevent complete oxidation. These soils, therefore, are often highly acid, and this condition is undoubtedly due mainly to organic acids. But by way of contrast it must be observed that sandy soils and heavy clays, which do not contain sufficient organic matter to produce an appreciable acidity, are often highly acid and non productive.
In this work one heavy silt loam soil, one soil somewhat sandy, both low in organic matter, and a loam soil rather high in organic matter were used, for the purpose of studying the change's which occur, the rate of change, and to some extent the final products of the reactions.
