Discusses organic matter, the carbon cycle, and the vital role of microorganisms and macroorganisms (like earthworms) in decomposition and nutrient cycling. 2. Soil Dynamics and Environment
Soil's role in carbon sequestration and filtering pollutants.
Explains how to determine nutrient needs, the timing of fertilizer applications, and precision farming techniques.
A new chapter in this edition explores no-till and hoe-till methods, cover crops, and crop rotations to improve soil health. 3. Soil Management and Classification
Examines the rock cycle, weathering processes, and the five factors of soil formation (parent material, climate, topography, biota, and time).
The book builds a foundation by exploring the three pillars of soil science:
The 6th edition emphasizes that soil is not just for farming. It includes expanded sections on:
