Edaphology

From Wikipedia, the free encyclopedia

Edaphology (from Greek: έδαφος , edaphos, "ground"; and λόγος, logos, "knowledge") is one of the two main branches of soil science, the other being pedology. Edaphology is concerned with the influence of soils on living things, particularly plants. The term is also applied to the study of how soil influences man's overall use of the land. General subfields within edaphology are agricultural soil science (known by the term agrology in some regions outside of the United States and Canada) and environmental soil science.
