Data mining process illustrative example

Acidity is a major limitation to soil productivity in much of the world. Although acidification is a natural process in many soil environments, agricultural practices and pollution from industrial, mining, and other human activities have accelerated the process. It is important that acidity be understood in terms of its fundamental chemistry so that soil management and remediation schemes are based on sound principles rather than empirical knowledge that may only be locally relevant. This chapter attempts to provide this understanding, and uses some example field data to illustrate important principles.
