Produktbeschreibung
Excerpt from University of California Publications in Agricultural Sciences The student of soils in the humid region, when for the first time exploring soils in the arid region, is invariably struck with the extraordinary depth of the latter as against the very shallow nature of the former. Taken by and large, and excepting the faulty soils, including those underlaid at no great depth by stiff clay, coarse gravel, hardpan, or original rock, respectively, the soils of the arid region very commonly show a depth of at least eight to ten feet, and, when viewed in section, exhibit such a striking uniformity in texture and color as to attach to this unusual condition, in the mind of the observer, a certain marked practical and scientific interest. The full significance to crops of the arid region of this extraordinary condition in our soils was first realized and pointed out by Hilgard and was made the subject, by him and Loughridge, of a comprehensive investigation on the "soil-columns" of California, a large part of which is completed, but some of which is still in progress. The study of the soil-columns of California comprised what might be looked upon as a very thorough partial soil survey of California.
