Final answer:
Warm season turfgrasses have specific pH requirements for optimal growth and cannot tolerate a soil pH below 6.5 or above 7.2.
Step-by-step explanation:
Warm season turfgrasses cannot tolerate a soil pH that is below 6.5 or above 7.2. Turfgrasses are plants that are commonly used for lawns, golf courses, and sports fields. They have specific pH requirements for optimal growth and health.
Soil pH is a measure of the acidity or alkalinity of the soil. It is important for plants because it affects nutrient availability and the activity of soil microorganisms. If the soil pH is too low or too high, it can hinder the turfgrass's ability to take up essential nutrients and impair its overall health.
For example, if the soil pH is below 6.5, it is considered acidic and may result in nutrient deficiencies, such as iron and manganese. On the other hand, if the soil pH is above 7.2, it is considered alkaline and may lead to nutrient imbalances and poor turfgrass growth.
