The document analyzes and compares the chemical and microbial composition of farm soil and forest soil. The farm soil had lower organic content than the forest soil but was better suited for plant growth. The forest soil had higher organic content which supported more microorganisms but the acidity levels needed to be adjusted to protect nitrogen-fixing bacteria. Overall, both soils benefited from organic amendments but the farm soil required additional organic matter to support beneficial microbes and earthworms.

4. Also, soil is a/an: Great integrator Producer and absorber of gases (CO 2 and others) Medium for plant growth Medium of crop production Home to organisms (plants, animals and micro-organisms) Waste decomposer Snapshot of geologic, climatic, biological, and human history Source material for construction, medicine, art, etc. Filter of water and wastes Essential natural resource Medium of heat and water storage
