Moisture mapping for water management success
The fine folks at Turf Republic bring us Dr. Doug Soldat discussing how soil moisture mapping with probes is rapidly replacing the older practice of irrigation audits. According to Soldat, the value of a moisture probe for calibrating an irrigation system and understanding your soils ‘is hard to overstate’.
Though a Distribution Unit (DU) measure of 80 is considered about as good as it gets for turf, and anything below 60 is generally frowned upon in the textbooks, the mitigation of low or high DUs is more complicated. Soil moisture mapping using GPS-enabled probes can provide a more meaningful view of your water management puzzle according to Soldat.
