Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Color of Soils The color of soils has long occupied the attention of both geologists and agriculturists and has considerable importance theoretically and practically. Theoretically the color is of importance as a guide to the origin and processes involved in the formation of the soil and as an indication of the relative age of any particular soil. It is of practical importance because it determines to a greater or less extent the absorption of the sun's energy, and is often a guide to the drainage conditions, to the crop adaptations, and to the cultural methods best suited to the soil. It is the object of this bulletin to publish the results of an investiga tion-into the causes of certain colors in soils, and particularly the causes of differences in color between the popularly named red and' yellow soils in connection with the agricultural significance of Such differences. In, addition to this, certain of the chemical and physical properties of iron compounds and their solutions will be considered It must be recognized that soil colors are not pure colors, but at best are Shades and tints. Thus the material by which soils ordinarily considered red are colored is ferric ox1de, which itself is never a pure red, for it varies from dark brown to yellowish, and when in the soil it is further tinted and Shaded by other materials. When applied to soils the color descriptions used in this bulletin mean the tints and shades which for the sake of Simplicity are termed red, yellow, brown black, or Simple combinations of these.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Soils and Their Properties The recognition of the work done by micro-organisms marks a most important advance in our knowledge of the phenomena involved in the metabolism (gr. Metabole, change) of the' soil. Hitherto, investigation has been directed rather to the determination of the immediate effects of soil metabolism in pro'moting the nutrition of plants. But it is at least possible that the biological fac tors in metabolic activity may eventually be proved to be not less potent than the physical and chemical agents in effecting the disintegration of rocks, and thus in restoring to the soil those mineral ingredients which are undergoing incessant loss. Our knowledge of the biology of the soil is hardly yet in a sufficiently settled condition to be made the subject of an elementary manual. All that is attempted, there fore, In 'the following pages is to trace soils back to their parent rocks, to indicate some of their more important physical and chemical properties, and to give a brief account of the distribution Of soils within the British Isles. It is proposed to follow this Volume with another, in the same series, upon the practical management of the soil.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Organic Constituents of Soils The reports on the various phases of soil studies by the investigators who have preceded me in this symposium must have impressed you with the fact that the subject of soil fertility and infertility is by no means a simple matter of arithmetic, which involves only a few of the mineral constituents of the soil. It must also have become clear to you that the problem of soil fertility or infertility has not been solved by the application of these simple arithmetical means based on soil analysis or by the crop statistics accumulated in the years which have elapsed since Liebig first announced his views on soil fertility, which gamed for him for all time the title of "Father of Agricultural Chemistry." It is particularly gratifying to me, since I am to talk to you to-day on the subject of the organic constituents of soils, their chemical nature and other properties, that Liebig is also known as the "Father of Organic Chemistry." To what tremendous proportions and significance in the worlds industries and science this child of his (Organic Chemistry) has grown is familiar to all of you, and I assure you that Liebig, were he to return to-day, would be proud of its parentage. But I fear he would be displeased with his other child, as having made so little progress in the intervening years, although he started it in life strong and virile and full of promise. Up to a few years ago agriculture had not shared in the great impulses which modern science has given to other arts and industries, and the domination of the mineral-requirement theory proposed in the first half of the last century and accepted without adequate proof of its validity is largely responsible for the lack of development in agriculture, commensurate with the enormous strides of other arts and industries under the guidance of modern scientific thought and research. But a new era of scientific inquiry is at hand, and all phases of scientific endeavor are being applied to the solution of the problems connected with soil fertility and infertility - lines of endeavor which were not even known in Liebig's time, but which to-day are well-recognized factors in soil fertility.

From its treasury it has been estimated1 that we drew last year (1909) more than and its possibilities are as yet only partially realized. There are still in this country millions of acres which have never felt the plow, while those which are now under cultivation can, by the application of scientific principles, be made to produce many times the present value of their products. How to use and not abuse this great resource is the most important problem which faces the farmer of to-day - one worthy of the best efforts of our most pro found and learned scientists; for upon its solution depends the future prosperity of the nation.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Red Clay Soil of Porto Rico In 1902 the Bureau of Soils made a soil survey of a strip of country 10 miles wide extending from Arecibo to Ponce.1 Within this area 19 different types of soil were encountered, and this by no means embraces all the soil types, that occur on the island. One Of the chief types in respect to area, though not in fertility, is the red. Clay soil which is classified by the Bureau of Soils as Adjuntas clay. During the last six years considerable experimental and analytical work concerning the nature and treatment of this red clay soil has been carried on. The experiments are being continued, but inas much as such work is never really closed, it has seemed. Advisable to publish the results obtained thus far, with the idea that although they do not definitely answer all questions that may arise concerning this soil, they should aid in its more intelligent and profitable treat ment.
