The maintenance of an optimal level of moisture in the ground implies a low water pressure therein. The moisture that remains is near field capacity, which is very difficult to achieve with other irrigation systems. This creates the need to water daily creating the possibility of waterlogging and root suffocation. The situation necessitates frequent intervention because of constant movement of water may lead to excessive leaching of nutrients.
These renewable energy sources are very useful where there is no access to mains electricity. The cost price is generally cheaper because of lower costs of maintenance and minimal environmental impact than pumping systems powered by internal combustion engines. With electric pumps, deeper aquifers can be achieved than with traditional wells, where it is difficult and dangerous to cross the 20-meter mark. However, in some instances, farmers drill to 1000 meters for agriculture.
Micro-irrigation delivers water to the plant roots in a localized fashion. It is a water saving technology, which prevents further runoff. It may also be done through infiltration or by means of buried porous pipes. Irrigated agriculture is the supply of significant quantities of water to crops through various artificial methods. This type of agriculture requires capital investment and careful water infrastructure: canals, irrigation, sprinklers and pools, which entails advanced technical development. Irrigated crops typically include fruit, rice, cotton, vegetables and beets.
Sprinkler or drip equipment connected to computerized systems can regulate amount, humidity and fertilization used. The drip system is very suitable for places where water is scarce. To implement an efficient irrigation system, users should carefully consider the water-plant-soil matrix. There is also the exudative textile system, which was created in the '80s by the French winemaker Rene Petit, who concluded that the existing systems had severe limitations and drawbacks due to its design and they were restricted by the material used in manufacture.
Irrigation and drainage manage water sources to promote agricultural production. The impact depends on the type of water source (surface or underground), its storage form, the transmission and distribution systems, and methods of delivery or field application. For a long time, surface water (primarily rivers) were used for this purpose.
However, the mechanism needs higher initial investment. The drip variant was first tested in Germany in 1860 and in the U. S. In 1918 through porous or perforated pipes buried underground. The system proved expensive for the kind of pipes that were used and had clogging problems because the roots of plants plug outputs.
Irrigation water is obtained from rivers, lakes or continuous streams of natural water wells (which get their water from underground aquifers) or wastewater treatment stations. This is in addition to desalination of sea water and to a lesser extent of salt lakes, which have the risk of salinizing land.
This is in addition to creating a more humid micro-climate. The expansion and intensification of agriculture which provides irrigation can cause increased erosion; contaminate surface and groundwater with agricultural biocides; reduce water quality. Increases levels of nutrients in water producing algal blooms, proliferation of aquatic weeds and eutrophication of irrigation canals and waterways downstream. Thus, greater amounts of agricultural chemicals are required to control the increasing number of pests and crop diseases.
