Riassunto:
Soil Sampling and Methods of Analysis is a practical methods manual and resource handbook that covers a wide array of methods for analyzing soil chemical, biological, biochemical, and physical properties. Soil testing for plant nutrients and methods to characterize organic soils and frozen soils are also provided. The book presents recent improvements in methodology, outlines new methods, and characterizes the best methods available for selecting appropriate analysis techniques. Methods have been selected for their accuracy, speed, and ease of duplication. References are provided for each method. The book is ideal for scientists, engineers, and students in agriculture, horticulture, forestry, geography, remote sensing, environmental science, and land-use planning.
