Variable rate irrigation system develophing on hose reel type irrigation systems

Irrigation is the most important inputs in agricultural production. The annual total of consumable water potential of our country is 112 billion m3. Technically and economically, the water used in the irrigable area for the average plant pattern is 96 km3/year, while the need for the total irrigable area is determined as 296.5 km3/year. Therefore, the economical use of existing water requires the use of precision agriculture technologies. In our study, hose reel type irrigation system, which is one of the application techniques of agricultural irrigation, was examined and a system in which the amount of irrigation was adjusted by computer according to the soil type was designed within the scope of precision agriculture applications. Our system provides a variable level of irrigation by using the location, speed and flow values obtained from the machine, according to the soil type and irrigation need specified in the pre-prepared databases of the land. A hose reel machine that performs uniform irrigation with the additions of software and hardware, controlled by a computer system, provided the desired variable level irrigation efficiency by detecting and controlling the location of the machine and the irrigation speed. The first part of the flow measurement system (irrigation part), the position and velocity values are taken, and the wireless transmission system that provides the transmission of these data, the second part of the control system in the irrigation machine where the operating speed of the irrigation machine is adjusted by processing these data. In the study, the machine, computer and control systems work in harmony with each other and it is foreseen that the efficiency of irrigation will increase, the prevention of water loss, as well as the increase in efficiency with effective irrigation.
