Kansas Agricultural Experiment Station Research Reports
Soil moisture sensors (SMSs) are a useful tool that aid in data-driven water management decisions. However, default factory calibrations can be inaccurate and soil-specific calibrations are often required to obtain higher accuracy in the determination of soil water storage and plant available water. In this study, we conducted a lab calibration for the Field Scout TDR 300, which is a popular SMS used in the turfgrass industry. Five soils of different soil textural classes were packed in containers with known soil moisture for the laboratory calibration. The logarithmic model best fit the data for the course- and fine-textured soils, with …

Irrigation Scheduling Based On Soil Moisture Sensors And Evapotranspiration, J. Aguilar, D. Rogers, I. Kisekka
Kansas Agricultural Experiment Station Research Reports
Irrigation scheduling is crucial to effectively manage water resources and optimize profitability of an irrigated operation. Tools that can be customized to a field’s characteristics can greatly facilitate irrigation scheduling decisions. Soil moisture sensors and the evapotranspiration (ET)-based KanSched are two of the tools that could be implemented in an irrigated farm. Focusing on the installation of soil moisture sensors, demonstration set-ups were established at the Southwest Research-Extension Center plots in Garden City, Kansas, and in a producer’s field, each with three types of moisture sensors at different depths. Among others, this project validates the importance of moisture sensors being …
