Course Overview
This introductory course delves into the fundamental aspects of soil science, encompassing soil formation, classification, physical and chemical properties, fertility, and management practices. It aims to provide students with a comprehensive understanding of soil as a vital natural resource.
๐ฏ Learning Objectives
By the end of this course, students will be able to:
-
Understand Soil Formation: Describe the processes and factors involved in soil genesis, including weathering and parent material influence.
-
Classify Soils: Utilize soil taxonomy to identify and categorize different soil types.
-
Analyze Soil Properties: Assess physical properties like texture, structure, and porosity, as well as chemical properties such as pH and nutrient content.
-
Evaluate Soil Fertility: Understand nutrient cycles, soil amendments, and the role of organic matter in maintaining soil health.
-
