Excerpt from Studies in Soil OxidationSchreiner and Reed0 more recently studied the relation between the oxidizing power of wheat roots and soil fertility. They found that: (l) The oxidizing power of plants grown in extracts of productive soils was greater than that of plants grown in extracts of unproductive soils, (2) treating the soil extracts with an absorbing agent was usually beneficial to oxidation, (3) the distillate of a poor soil extract which contains volatile toxic compounds was less favorable to oxidation than the residue remaining after distillation, (4) the presence of added toxic organic Substances in solution was deleterious to the oxidizing power of the plant roots, (5) the oxidizing power of the plant, espe cially in the presence Of nitrates or lime, was able to lessen the toxicity of such solutions, (6) calcium salts and phosphates also increased the oxidizing power of the wheat roots, while potassium Salts tended to retard oxidation.The work of Schreiner and Reed showed clearly that oxidation by plant roots is a factor which has considerable agricultural interest, especially from the viewpoint that such oxidation is able to change the organic matter in the medium in which the plant is growing and that processes promoting oxidation 'play a large part in the best methods of soil cultivation, tillage, and crop rotation.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
