tailieunhanh - Soil Sampling and Methods of Analysis

This volume is an update of the book, Soil Sampling and Methods of Analysis, first published in 1993. The aims of this second edition remain the same as those of the earlier edition—to provide a compilation of soil analytical and sampling methods that are commonly used, straightforward, and relatively easy to use. The materials and procedures for these methods are presented with sufficient detail and information, along with key references, to characterize the potential and limitation of each method | Soil Sampling and Methods of Analysis Second Edition 2006 by Taylor Francis Group LLC. In physical science the first essential step in the direction of learning any subject is to find principles of numerical reckoning and practicable methods for measuring some quality connected with it. I often say that when you can measure what you are speaking about and express it in numbers you know something about it but when you cannot measure it when you cannot express it in numbers your knowledge is of a meagre and unsatisfactory kind it may be the beginning of knowledge but you have scarcely in your thoughts advanced to the state of science whatever the matter may be.
