Agricultural geology – Definition & Meaning

Agricultural geology is a branch of geology that deals with the study of earth materials, processes, and their relationship with agriculture. It involves the study of soil, rocks, minerals, water, and other natural resources that are essential for crop production. Agricultural geology is an interdisciplinary field that combines geology, soil science, agronomy, and environmental science to address the challenges of sustainable agriculture.


Agricultural geology is defined as the application of geological principles and methods to the study of agriculture. It involves the investigation of the physical and chemical properties of soil and rocks, the analysis of water resources, and the assessment of environmental factors that affect crop growth and productivity.
According to the International Union of Geological Sciences, agricultural geology is “the science that applies the principles of geology to the study of agricultural and environmental problems related to the management of soil and water resources for sustainable agriculture.”


The origin of agricultural geology can be traced back to the early 20th century when scientists began to recognize the importance of soil and water resources for agriculture. The first agricultural geology research center was established in the United States in 1935 at the University of California, Berkeley. Since then, agricultural geology has become an important field of study in many countries around the world.

Meaning in different dictionaries

According to the Oxford English Dictionary, agricultural geology is “the branch of geology concerned with the study of the geological factors influencing agriculture, especially soil formation and water supply.”
Merriam-Webster defines agricultural geology as “a branch of geology concerned with the study of the physical and chemical properties of soils and rocks, the analysis of water resources, and the assessment of environmental factors that affect crop growth and productivity.”


Agricultural geology is closely associated with soil science, agronomy, environmental science, hydrology, and geotechnical engineering. It is also related to other fields of study such as geophysics, geochemistry, and geohydrology.


Some synonyms of agricultural geology include agrogeology, soil geology, and pedology.
