A method of irrigation that has been spreading more and more in recent times and for different types of crops is the so-called "drip" method, which also allows a considerable saving of water.
What is it
Drip irrigation consists of a targeted irrigation system for each plant: therefore, the area of the root of the plant itself is wetted, optimizing water consumption and avoiding waste. This type of irrigation has a long history, and similar methods were also used in ancient times: at that time it was carried out by filling a clay container with water, which emptied slowly, irrigating the plants constantly. Now, the method of drip irrigation is specializing more and more, especially in the field of fruit tree cultivation (but recently it has been increasingly used also for the cultivation of vegetables, flowers and other plants). There are different types of plants, built according to the needs of the grower: they range from plants with constant irrigation to those intermittently, up to the underground plants (not yet widespread in Italy), which allow the water to wet directly plant roots, consuming even less liquid, optimizing yield more and more and avoiding stagnant water, which is harmful because they can cause the roots to rot. Usually it is possible to dose both the water pressure and its quantity, making sure that each plant has the necessary irrigation, also according to the different types of soil, the climate and the needs of the plant itself. Drip irrigation has been used consistently in the agricultural and nursery industry since the 1960s: since then, it has naturally become increasingly specialized, with particular attention to new industrial crops. Currently, drip irrigation is widely used in the production of vegetables intended for large-scale distribution.
