Is a soil test an excellent method for assessing the nutrient content inside turf grass plants?

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

Answer: (B)

Soil tests tell you what nutrients the soil can supply and how soil properties like pH affect that availability. They do not measure the actual nutrient content inside turfgrass tissues at a given time. Plant nutrient content depends on uptake by roots, which varies with root health, moisture, growth stage, temperature, and other factors. Because of this, a soil test is not an excellent method for assessing how much nutrient is inside the plants. To evaluate plant tissue status, use plant tissue analysis (such as clipping or foliar tests), which directly measures what the plant is actually accumulating.
