Localized irrigation offer some agronomic benefits, such as controlling weeds in the soil. Increased production and fruit quality, and that low soil moisture stress is maintained throughout the crop cycle. Fertilization can be included in irrigation systems water, increasing efficiency, location and dose of fertilizers. In the same way, there may be other agrochemicals mixed with the water. The system allows simultaneous watering and presents no obstacle to navigate the field. Prevents leaching of soil nutrients and disease control is greatly improved.
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.
A modern way to water is the use of drip and micro that involve the application of water in a restricted area. These methods are suitable for areas where water is scarce, since the application is done in small doses and frequently. This allows better control of water and some other agronomic benefits.
Plant watering projects on a large scale using groundwater are a recent phenomenon. They are found mainly in large alluvial basins of Pakistan, India and China, where tube wells are used to exploit the phreatic water, along with irrigation mechanisms that use surface water.
The potential negative impact of large projects include waterlogging and salinization of soils; the greater incidence of food borne or water-related diseases; resettlement or changes in the lifestyles of local people; the increased amount of agricultural pests and diseases due to the non-occurrence of pest deaths during the dry season.
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.
