How often should soil pH be tested for turf management?

Testing soil pH every 1 to 3 years is recommended for effective turf management because it allows for a timely assessment of the soil's acidity or alkalinity, which is crucial for optimal grass growth and health. Soil pH influences nutrient availability, microbial activity, and overall soil quality. Performing this test regularly within this timeframe ensures that any necessary adjustments, such as lime applications to raise pH or sulfur to lower it, can be made to maintain a balanced environment for the turf.

This periodic testing strikes a balance between being proactive in nutrient management without being overly frequent, which can be unnecessarily costly and time-consuming. Testing every 6 months or once a year may lead to excessive interventions or monitoring without substantial changes in soil properties. Only testing when problems are observed can result in delayed responses to potential pH-related issues, possibly leading to unhealthy turf conditions.
