It is to provide the soil suitable amount of water that you need, which would maintain the level of soil moisture that helps plant growth process of irrigation soil of excess salts washed from the soil need, and keep the appropriate amount needed by the plant root, and transferring it to the ground, as it helps the plant to absorb the nutrients found in the soil through defrosting.
The task of irrigation activate the bacteria in the soil, and the function of these bacteria analysis of organic matter; Since the arrival of water to the roots of the soil and spread it maintains the temperature where commensurate with the plant, and reduce the severity of frost and its effects.
Water secret of the secrets of life of all kinds is whether underground, or rain, or others, because of limited water sources showed the importance of research and find ways for irrigation; So that they are modern and good for the exploitation of the best water and to reduce the wasted amount of water as much as possible, it was selected roads based on several things, including: topography, soil structure, and the time between the first irrigation time following the operation, and the type of plant to be Rih, and the availability of water in that region and the availability of labor.
Modern irrigation methods
There are several ways for irrigation, namely: irrigation using sprinklers, drip irrigation, surface irrigation. We will quote the specifications of each type of these methods.
It began to use this modern method of irrigation in the end of this century and has increased its deployment after World War II after the availability of the efficiency of pumps, pipes and light sprays load, in this way water is sprayed into the air through small holes in the tubes and pipes until they fall to the soil and vegetation surface in the form of spray of rain. The advantage of this method is that it enables farmers to add fertilizer and pesticides with water, as it can be used in the land is flat, it does not need hands working, and protect plants from frost, and works to maintain the temperature, and this way damage they lead to the emergence of salts on the surface of the soil.
In this way is added to the water in the form of drops of water under the plants directly, and is placed within the irrigation network end points for the exit of water, this method is useful in that they are suitable for the land of sand and desert, and working on the water supply, but the damage this method is that the establishment of irrigation networks which are of high cost, and they need to be working hands with high efficiency.
Are flooded by the soil, and this method features; Where it is easy to use, low cost and do not require the hands of trained workforce, but has the disadvantage of which it can not control the amount of water used for the plant, then so lead to loss of large amounts of water.
We regret it!
