Drip irrigation has many advantages over other irrigation methods:
Water drains evenly. This is true even on moderately sloping terrain. In addition, the method of compensated drippers allows you to evenly water on steep slopes and makes it possible to increase the irrigation area with the help of bends with drippers. With the help of droppers, along with water, fertilizers can be delivered directly to the roots of plants (fertigation). Water and fertilizer are delivered directly to the root system, thereby saving water and fertilizer. The amount of water in each plant can be optimized to suit different soil types, preventing water seepage beyond the root zone. With drip irrigation, the appearance of weeds is minimized. Between the beds, it is much drier, which makes it easier for workers and machines to have easy access throughout the season. It is possible to use low-quality water (salt water or treated effluents) because direct contact between the water and the leaves can be avoided, thus eliminating burns. With drip irrigation, salts are constantly washed out of the root system, which prevents the accumulation of salts in the immediate vicinity of the roots. This is important if saline soils are used or irrigated with salt water. Drip irrigation allows the use of treated wastewater because the water flows directly to the ground, minimizing health risks.
Drippers for the right amount of water (from a few to tens of liters per hour) can be
installed at any step to meet the needs of any crop. Drip irrigation is the most efficient irrigation method for saving water. Water enters directly into the soil next to the root system, which absorbs water immediately, while water evaporation is minimal. This property is especially important in the conditions existing in arid zones. In spray irrigation (sprinkling), evaporation is increased by wind,
and in drip irrigation, the effect of wind is minimal. High-quality drip irrigation equipment can be used for fifteen to twenty years if properly maintained. The water use efficiency ratio (WUE) is defined as the ratio between the amount of water used by plants and the total amount of water used for irrigation. Studies show that drip irrigation has a WUE of about 95%, compared to 45% for surface irrigation and 75% for sprinkler irrigation. In summary, it can be concluded that drip irrigation has many advantages over other irrigation methods and that it also outperforms surface and rainfall ratios in water savings, especially in conditions of limited water supply. The drip irrigation system is called the SYSTEM for a reason. Drip irrigation is not only irrigation hoses, but also devices for water purification and filtration, pipes and fittings for supplying and distributing water across the field, equipment for dissolving and dosing fertilizers, and, of course, automation.
