Produktbeschreibung
Excerpt from Soil Survey Field Book: Field Season, 1906 Two years have elapsed since the publication of the last issue of Instructions to Field Parties and Description of Soil Types. During these years the soils of many new areas have been studied and much additional information in regard to the general relation of the soils of the United States has been obtained. The correlation of the soils is a very difficult problem, and one which can not be definitely solved from the data obtained by the survey of a limited number of widely separated areas. Each additional survey throws new light upon the subject, and sometimes necessitates changes in the soil names used in the earlier reports. The student of soils will doubtless realize that the necessity for such readjustments is an inherent feature of work of this character. Appreciating the importance of the proper correlation of the soils, Messrs. Macy H. Lapham, Charles N. Mooney, J. E. Lapham, and Hugh H. Bennett - field men of wide experience - were detailed to assist Messrs. George N. Coffey and Jay A. Bonsteel in the revision of this publication. This committee has gone carefully over the reports of all the areas that have been surveyed, compared the descriptions and analyses of the soils, and made such changes as were necessary to bring each soil into its proper place in the classification. Every change made is believed to be a step in advance, no step has been taken except after the most careful consideration of all the questions involved, and it is believed that the subject has been handled in a conservative way. The present volume is definitive of the state of knowledge at the time of its issuance. However, the collection of data is going on and a fuller understanding of soil relationships is being gained as area after area is mapped. It follows that some changes in the present classification will yet be found advisable, and these will be made as their need becomes apparent. In this way, and only in this way, can a uniform and consistent exposition of the wonderfully varied soil resources of the country he ultimately accomplished.
