Which term refers to matching plants to the appropriate acidity level in the soil?

• A. Soil pH requirements
• B. Alkalinity tolerance
• C. Nutrient balance
• D. Salinity tolerance

Answer: (A)

Matching plants to the acidity level in the soil centers on soil pH and how it controls nutrient availability. Each plant has a preferred pH range where its roots can access essential minerals; if the soil is outside that range, nutrients may become unavailable even if they’re present. So the term that describes this practice is soil pH requirements. Think of the practical side: you might test your soil pH and either adjust it with soil amendments (like lime to raise pH or sulfur to lower it) or choose plants that naturally fit your existing pH. This ensures plants can take up nutrients efficiently. Alkalinity tolerance refers to how well a plant handles high-pH conditions, which is related but not the general concept of selecting plants for their pH needs. Nutrient balance focuses on the amounts and ratios of nutrients, not the soil’s acidity. Salinity tolerance deals with salt levels in the soil, not pH.
