Geology applied to agronomy

Focusing on the critical relationship between farming and geology, the book emphasizes the importance of understanding soil as a vital resource for plant growth. It explains how arable land not only supports plants but also provides essential minerals for their development. Each harvest depletes these minerals, necessitating the use of manure or fertilizers to replenish the soil. The text advocates for a thorough study of the soil's physical, chemical, and biological properties as foundational to effective agronomy practices.
