Extract

Since its inception in 1894 the American Soil Bureau has investigated many important problems and obtained results which are now common knowledge in this country, but its earlier Bulletins are altogether eclipsed in interest and far-reaching significance by a series recently published. In presenting an account of these it will be most convenient to set out first the purely scientific part of the work, and then the practical applications. This is the logical order and also the order in which the results were actually obtained.
