What type of sampling method involves removing a square foot of sod?

The sampling method that involves removing a square foot of sod is known as square-foot sampling. This technique allows for a detailed assessment of the soil and the organisms inhabiting that area, providing insight into pest populations, turf health, and soil conditions. By physically removing a section of turf, you can directly analyze not only the pests present but also the overall nutrient status and structure of the soil, leading to more accurate pest management decisions. This method is highly effective in evaluating localized issues within a larger area of turf, providing valuable data for subsequent treatment or management strategies.
