What term is defined as the measure of acidity or alkalinity?

• A. pH
• B. Photosynthesis
• C. Scouting
• D. Stress Factors

Answer: (A)

pH is the measure of acidity or alkalinity. It’s a logarithmic scale from 0 to 14, with 7 being neutral; below 7 means acidic and above 7 means alkaline. This matters in turf care because soil pH controls the availability of nutrients to grass roots—nutrients can be present but unavailable if the pH is off. Most turfgrasses prefer a soil pH around 6.0 to 7.0, though some species tolerate slightly different ranges. You can adjust pH by applying lime to raise it or sulfur to lower it, and you’ll typically test pH with a soil test or pH meter. The other terms mentioned (photosynthesis, scouting, stress factors) relate to different concepts and do not define acidity or alkalinity.
