True or False: A soil pH of less than 7 is classified as acidic.

A soil pH of less than 7 is indeed classified as acidic. The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 indicate increasing acidity, while values above 7 indicate alkalinity. This classification is important in various contexts, including agriculture and horticulture, as soil pH can significantly impact nutrient availability, microbial activity, and overall plant health.

Understanding soil pH is essential for managing soil health and optimizing plant growth because different plants have varying pH preferences. For example, certain plants thrive in acidic conditions, while others prefer more alkaline soils. Therefore, maintaining the proper pH for target plants can enhance their growth and yield.
