Locating The Variability Of Soil Water Holding Capacity And Understanding Its Effects On Deficit Irrigation And Cotton Lint Yield, Heath Adam Duncan
Masters Theses
Precision irrigation equipment such as variable-rate center pivots is readily available to Tennessee growers and producers; however, little research exists describing its application to cotton grown in Tennessee. In order to optimize the use of variable-rate irrigation equipment and water resources, two experiments were performed to determine (1) whether or not ground-penetrating radar (GPR) and electrical conductivity (EC) measurements can be used to delineate variable-rate irrigation zones and (2) examine the response of cotton lint yield to varying rates and duration of irrigation.
GPR and EC measurements were recorded, validated using soil cores, and used to identify the subsurface variability …
