What is the Role of Drip Irrigation Drip in Agriculture? ~ Irrigation - "the science of artificial application of water to the ground or the floor." The first signs of irrigation and therefore agriculture, drip irrigation appeared around 10,000 years and children dripping occurred around 6000 BC .. Previously people were hunter-gatherers, collect their food, as they find around them. While there are still some societies of hunters -trofosyllekton today, the vast majority of the world population now dependent on agriculture and farming for survival.

According to the United States Geological Survey, about 60% of fresh water in the world comes from wells, rivers or lakes, to irrigate crops for humans and animals. As the world population explodes over 7 billion euro, the need for high quality food is growing. This is a strain on the water supply in the world. According to Institute of Food and Water Watch, there are 1.4 billion people have no access to live in clean water. How can we justify many of the current irrigation practices, where there is plenty of fresh water is lost through evaporation and runoff?

As early as 6000 BC, many irrigation companies are often used to flooding during the rainy season and water harvesting during the remainder of the year. Archaeology has shown that pre-Columbian America, Sub-Saharan Africa, Persia, Egypt and China, to name only a few, the development of water collection systems, construction of dams and large irrigation canal networks of 4000-6000BC was. The pots Clay buried in the ground and filled with water flowing slowly in the soil environment, are developed in the plant.

Modern drip irrigation in 1866 was his childhood, such as farmers and researchers in Afghanistan began with clay irrigation and drainage pipes. In the 1960s, ice pipes used and the film drips, but the problem quickly clog the minerals in the water. Ironically, the drier parts of the world require drip irrigation, tend to be more difficult for water, which contain most of the inorganic salts, in turn clog the system.

With the sprinkler invention in the 1930s, agriculture and agriculture took a new dimension. Now, large areas of dry grassland could hungry planted with a variety of water cultures. With the advent of irrigation pivot center, more land was irrigated on the floor, where evaporation and wind up a large percentage of the water before it reaches the roots. Undoubtedly the most valuable innovation in modern agriculture is the perfection of the drip irrigation system. Although the most effective form of drip irrigation emitter is underground, there are some applications requiring micro-spray heads. As technology evolves and agricultural water supply decreases, subway systems can also be taken fully. be able to provide water to the roots, should be the only part of the moisture of the plants, causing huge saving water. It is estimated that traditional forms of irrigation, only 30-40% is effective. In this day and age of drought, climate change and population growth, waste up to one liter of water is a scam; And the situation becomes more gloomy annually. While drip irrigation once considered important was agriculture in the desert, which is gaining popularity in semi-arid and sub-humid in. There may be some disadvantages such as drip irrigation is clogging pipes, plastic degradation from the sun and the cost, but the benefits far outweigh the disadvantages.
