Irrigation systems which apply water frequently to crops (drip, center Pivot, and solid set sprinkler irrigation systems) can mantain relatively constant, high soil moisture levels in the soil. Therefore they contribute to higher transpiration rates.
The concept of applying fertilizers, herbicides, fungicides and other chemicals via center Pivot irrigation systems is fast becoming a major cost reducing method.
Some factors should be considered when deciding to chemigate through a center-Pivot irrigation system: soil type, center-Pivot location, topography, drift and runoff potential, machine characteristics, calibration…
