What is a disadvantage of soil that may affect plant growth?

• A. High air exchange
• B. Low water holding capacity
• C. High pore space
• D. Variable pH

Answer: (D)

A disadvantage of soil that can affect plant growth is variable pH. Soil pH is critical because it influences nutrient availability and biological activity in the soil. A variable pH means that the acidity or alkalinity of the soil can change, which can lead to inconsistent nutrient uptake for plants. Different plants have varying pH needs; for instance, some prefer acidic soils while others thrive in alkaline conditions. If the soil pH fluctuates significantly, it may create conditions that are not ideal for optimal plant health, leading to poor growth or even plant failure. Understanding and maintaining stable pH levels can help achieve better and more predictable results in plant cultivation.
