• A. True
• B. False
• C. Sometimes
• D. Not sure

Answer: (A)

Probing depth is chosen to sample the root zone and current moisture profile. For most turfgrass, the majority of roots occupy the top 4 to 6 inches of soil, so checking moisture, texture, and compaction at that depth gives a reliable picture of the conditions that directly affect growth and irrigation needs. If moisture or compaction is unfavorable within that zone, you know you may need to water or aerate to improve root health. Deep probing isn’t typically necessary for routine turf checks; you’d probe deeper only for specific situations like deeper-rooted varieties or suspected drainage issues. So, four to six inches is usually sufficient when probing turf soils.
