Evaluating Various Soil Moisture Sensor Thresholds in Cotton in South Carolina

This research was conducted in South Carolina in 2018 & 2019 evaluating three different soil moisture sensor (Watermark 200SS) threshold values in cotton. A non-irrigated treatment was also included for comparison purposes. Overhead irrigation was applied to plots when sensor threshold values (-15, -30, and -60 kPa) were met. Cotton growth measurements were taken throughout the season, root core data for each plot was also obtained to help quantify rooting depth, surface area, length, etc. at 5-leaf and full bloom. Fiber quality and lint yield will also be collected.
