* Soil is often overlooked: People tend to focus on more obvious or complex factors, neglecting the fundamental, often less glamorous, aspects.
* Soil is complex and interconnected: Just as soil is composed of various elements and organisms, many problems and situations have multiple contributing factors. The answer might lie in understanding these interconnected elements.
