![]() The highest wetted depth in clay loam, sandy loam and sandy clay loam were 17, 26, and 25 cm while the wetted radius were 26, 24, and 22 cm, respectively. Results show that lateral water movement was highest in the clay loam while vertical movement was highest in sandy loam. The field data was subjected to statistical analysis using SPSS version 22.0 to formulate the models that relates the duration, flow rate, volume and hydraulic properties to wetted radius and depth. At intervals of 30 minutes, there was excavation to monitor the wetted radius and depth. The maximum duration of water application was 10 hrs. Water was applied to each soil type using drip irrigation set up at a constant flow rate of 1.3 l/hr. The objective of this study was to develop models that can help to determine the wetting radius (r), wetting depth (z) from surface point drip irrigation of three soil types (clay loam, sandy loam and sandy clay loam). This is to ensure precise placement of water and fertilizer in the active root zone. ![]() ![]() ![]() Information on wetting patterns under point source drip emitters is a prerequisite for the design and operation of the drip systems. Drip Irrigation is considered as one of the most efficient irrigation systems, provided the system is designed to meet the soil and plant condition. This study was carried out by identifying and selecting three soil types around the University of Agriculture, Makurdi, Nigeria to determine their physicochemical properties. ![]()
