Abstract. Algeria is a vast country with three climatic types and different water resources. These resources are limited especially in the climatic zone two where most staple crops (e.g. wheat) are cultivated. To manage these water resources efficiently, traditional irrigation systems should be replaced by those based on advanced technological techniques. This paper introduces an irrigation system prototype constructed at the department of Electrical Engineering, University of Setif in Algeria. This prototype allows the control of the amount of water dispensed to the plant according to its soil moisture. The circuit was built around an Arduino microcontroller. A program was developed and burned into the microcontroller which was able to sense the amount of the moisture in the plant soil through a moisture sensor. According to this moisture quantity, the microcontroller is to take decision to on or off a small pump for an optimum time and flow speed. The pump was driven by a direct current motor which was controlled by a pulse width modulation dc chopper. The system is enhanced by a liquid crystal display to inform the operator about the moisture percentage, status of the pump and its speed.

Traditional Irrigation

Traditional irrigation systems do not take into consideration the conservation of water. Therefore, automating the plant watering systems to reduce water wastage and loss would be key to water conservation as a means of making use of water wisely and responsibly. In this chapter, a smart irrigation system that helps control the amount of water applied to crops is proposed and developed. The system controls the ON/OFF state of the water pumping motor based on the soil moisture sensor reading. Other sensors incorporated in the system are the water level sensor and light dependent resistor. The system leverages on the Arduino Uno microcontroller development board to collect input signals from the three sensors. The water pump operates depending on the value of the output signal received by the relay module. This technique of watering is feasible and very affordable and reduces human intervention in field watering.

In recent years, the best system of irrigation is studied by reducing the wasted amount of water and electricity. Automatic irrigation is the use of a device to operate irrigation structures so the change of flow of water from one bay, or set of bays, to another can occur in the absence of the irrigator. In this work, automatic control system of solar irrigation implemented practically using Arduino board. This photovoltaic (PV) system is applied in the garden of Engineering Technical College- Mosul (city in Iraq). PV system can be adjusted by many regions in Iraq where it planned to connect on small part of land. Irrigation process is controlled depending on moisture sensor that connected to sense the soil moisture and giving data to Arduino read pin. According to the program that uploaded to Arduino, DC pump can be controlled as ON-state or OFF-state as respect to the soil moisture percentage ratio. Finally, the practical results are approximately similar to that obtained from proteus Arduino simulator.

s. Management of water for irrigation in Bali has been exist since the IX century, which is known as Subak. Subak is traditional irrigation system and it is closely associated with the principle of TriHitaKarana. The elements and facilities of subak include: irrigation networks, organizational structures and regulation. Distribution of water uses a comparison unit called ayahan. One unit of ayahan entitled to one tektek or one kecoran which is a unit of water flowing through the cross section of traditional spillway on a countinuous basis. If water availability is limited, then water supply is managed by rotation basis called pergiliran or nyorog system that based on different planting time. The principle of nyorog is the upstream section get water first (called ngulu), the midstream obtain water after the upstream had finished cultivating of soil (called maongin), and the downstream called ngasep. In rainy season, rice planting is simultaneously done in all area of subak, which is called kertamasa. Meanwhile in dry season called gadon, rice planting is scheduled by principles of nyorog or rotation. The arrangements of water resources and the settings of cropping pattern is stated in regulation (awig awig). Water distribution were managed ​​by the administrators of subak within the territory, or through an agreement between the territories’ administrators. The Sedahan and Sedahan Agung, whom in charge as subak’s adviser have very important role in the coordination on management and use of water. Recently they are facing uncertainty in existence, and causing lost of coordination in resolving various problems. In the future, the functioning of the Sedahan and Sedahan Agung is needed.

The Impact

Climate change and its impact on already scarce water resources are of global importance, but even more so for water scarce countries. Apart from the effect of climate change on water supply, the chill unit requirement of deciduous fruit crops is also expected to be affected. Although research on crop water use has been undertaken, researchers have not taken the future climate into consideration. They also have focused on increasing temperatures but failed to relate temperature to chill unit accumulation, especially in South Africa. With a view of helping farmers to adapt to climate change, in this study we provide information that will assist farmers in their decision-making process for adaptation and in the selection of appropriate cultivars of deciduous fruits. Crop water use and chill unit requirements are modelled for the present and future climate. Results show that, irrespective of the irrigation system employed, climate change has led to increases in crop water use. Water use with the drip irrigation system was lower than with sprinkler irrigation as a result of efficiency differences in the irrigation technologies. It was also confirmed that the accumulated chill units will decrease in the future as a consequence of climate change. In order to remain in production, farmers need to adapt to climate change stress by putting in place water resources and crop management plans. Thus, producers must be furnished with a variety of adaptation or management strategies to overcome the impact of climate change.

Crop Field

In the current condition, it is difficult to increase plant development and reduce expenses in agricultural sectors; nevertheless, an advanced thought leads to the use of an automated model that introduces automation in the irrigation system, which can aid in improved water and human resources management. An automated model has been developed using sensors and microcontroller technology, to make the most efficient use of water supply for irrigation. A soil moisture content detector is inserted into the soil of the crops, and an ultrasonic sensor is placed above the soil of the crops to measure the water level after irrigation has begun. A C++ program with threshold values for the moisture sensor was used to start the system in the crop field depending on the soil moisture level, and an ultrasonic sensor was used to control the water in the crop field. The Arduino UNO board is a microcontroller inbuilt of Atmel in the mega AVR family (ATMega328) and the sensors were used to lead the model in turning ON/OFF. A microcontroller was included in this model to run the program by receiving sensor input signals and converting them to soil water content and water level values in the crop field. The microcontroller began by receiving input values, which resulted in an output instructing the relay to turn on the groundwater pump. An LCD screen has also been interfaced with the microcontroller to show the percentage of moisture in the soil, field water level, and pump condition. When the soil moisture level reaches 99 percent and the water level reaches 6 cm after 2.5 and 4 minutes, respectively, the pump is turned off. This model, according to the study, might save water, time, and reduce human effort.
