| Abstract | ||
| The limited irrigation water in light of the prevailing climate changes bad management of water resources, as the excess additions of irrigation water are a waste of both water and efforts at the same time, in addition to the washing and loss of nutrients and the deterioration of soil characteristics. Rationalising water use by following irrigation scheduling has become an urgent necessity. This article included a review of the most important methods used in scheduling irrigation. The gravimetric method has practical problems that cannot be avoided. It is possible to rely on electrical resistance panels to schedule irrigation when manufacturing a reader for this sensor through an electronic card. The method of neutron meds has disadvantages, including the health risk associated with exposure to neutrons and gamma ray. The useful limits for most tensile gauges are up to 0.8 bar as the maximum for pulling force. The use of the GS3 sensor is the best, as it is the most accurate to monitor soil moisture changes. The Diviner 2000 soil moisture sensor is a fast and accurate device to follow the change in the volumetric moisture content of the soil directly. The use of Aqua Crop under conditions of climate change makes it possible to simulate actual water consumption and water productivity. The SEBAL algorithm, a remote sensing technology, can aid decision-makers, researchers, and farmers in estimating evapotranspiration and enhancing irrigation water management at the field level. | ||
