Final answer:
The incorrect statement about soil is that its health depends on air pressure from the density of gas molecules in the air. Soil health is influenced by components such as inorganic minerals, organic matter, water, air, and living organisms, not air pressure.
Step-by-step explanation:
The statement about soil that is not correct is "Soil health depends on air pressure caused by the density of gas molecules in the air." The health of soil is affected by various factors including its composition of inorganic minerals, organic matter, water, air, and the living organisms within it. Factors such as vegetation, soil compaction, and water presence play significant roles in determining soil properties and fertility.
Soil properties are indeed influenced by living components, contradicting the statement that soil properties depend only on nonliving components. Living organisms, like microbes and plants, contribute to the organic matter in the soil and affect soil structure, nutrient cycling, and overall health.
The productivity of plant life is greatly influenced by soil properties, as soil quality affects the availability of water and nutrients required for plant growth. Additionally, organic material, including decomposed plant and animal residues, is essential for maintaining soil structure and fertility. Therefore, it is integral to soil composition and health.
