Answer:
True
Step-by-step explanation:
Probing the soil to a depth of 4 to 6 inches is generally sufficient for turf soils, as this depth allows you to assess the root zone and the condition of the soil where most of the grass roots are located. However, the specific depth for soil probing may vary depending on factors like the type of turfgrass, local soil conditions, and the specific goals of soil testing or analysis. In many cases, a 4 to 6-inch depth provides valuable information for turf management and maintenance.
