Interest . Irrigation sagacity and irrigation efficiency go hand-in-hand , i dont think, there is something so significant to separate between the two...
Irrigation sagacity is a qualitative while irrigation efficiency is a quantitative attribute. Both sagacity and efficiency are necessary, as mentioned before. A high irrigation efficiency usually requires a high irrigation sagacity on the part of the operator. However, irrigation efficiency can also be obtained by the use of electronic sensors and computing technology, with relatively minimal human intervention, although you can also say that the design of the irrigation control systems required sagacity. Presently, with the relatively inexpensive access to computers, cell phones, etc. and low cost of sensors, and the pressing need to protect the water resources, there an growing trend to using irrigation control systems intended to increase water use efficiency.
