Ancient Understanding:
Since ancient times, humans have recognized soil as vital for growing crops and sustaining life. Early civilizations such as those in Mesopotamia and Egypt developed farming techniques relying on fertile soil along riverbanks.
Scientific Study (18th-19th Century):
Soil science, or pedology, emerged as a formal discipline in the 18th and 19th centuries. Scientists like Vasily Dokuchaev, a Russian geologist, pioneered the study of soil formation and classification in the late 19th century, identifying soil as a natural body with distinct layers called horizons.
Modern Importance:
Today, soil is studied extensively for its role in agriculture, environmental health, and climate change. Sustainable soil management is crucial to maintaining food security and ecosystem balance.
