Soil moisture vs. turf quality

View Larger

July, 2008, poa annua green, Southern California. Volumetric soil moisture evaluated using a Spectum Technologies TDR300 soil moisture probe and corresponding turf quality evaluated visually on a 0 to 9 scale with 0 representing dead turf and 9 representing the highest quality turf (refer to photo of damage). Good turf quality was associated with soil moisture above 18%. Excessive soil moisture is also not desired. Maintain soil moisture between 18 and 25% for good turfgrass performance.
