Because of the free access open access journals impact factors are improving. Open access journal articles are essentially peer-reviewed and available for access through the directory of Open Access journals.
The open access movement gained popularity after the Budapest meeting of the Open Society Institute in Under this provision, pre-prints that are yet to be reviewed can be posted online. This enables the fellow researchers of the latest updates and findings. This is provision also meant to transmit and link to the subsequent publications in the same domain. Drip irrigation is a form of irrigation that saves water and fertilizer by allowing water to drip slowly to the roots of many different plants, either onto the soil surface or directly onto the root zone, through a network of valves, pipes, tubing, and emitters.
It is done through narrow tubes that deliver water directly to the base of the plant. It is chosen instead of surface irrigation for various reasons, often including concern about minimizing evaporation.
Agricultural chemicals can be applied more efficiently 7. Fan Sheng-Chih Shu, written in China during the first century BCE, describes the use of buried, unglazed clay pots filled with water as a means of irrigation. The first experimental system of this type was established in by Blass who partnered later withKibbutz Hatzerim to create an irrigation company called Netafim. Together they developed and patented the first practical surface drip irrigation emitter.
Modern drip irrigation has arguably become the world's most valued innovation in agriculture since the invention of the impact sprinkler in the s, which offered the first practical alternative to surface irrigation. Drip irrigation may also use devices called micro- spray heads, which spray water in a small area, instead of dripping emitters. These are generally used on tree and vine crops with wider root zones. Subsurface drip irrigation SDI uses permanently or temporarily buried dripperline or drip tape located at or below the plant roots.
It is becoming popular for row crop irrigation, especially in areas where water supplies are limited or recycled water is used for irrigation. Careful study of all the relevant factors like land topography, soil, water, crop and agro-climatic conditions are needed to determine the most suitable drip irrigation system and components to be used in a specific installation.

Drip tape drip tube 5. Injectors 6. Filtration system 9. Most large drip irrigation systems employ some type of filter to prevent clogging of the small emitter flow path by small waterborne particles. New technologies are now being offered that minimize clogging. Some residential systems are installed without additional filters since potable water is already filtered at the water treatment plant.
Virtually all drip irrigation equipment manufacturers recommend that filters be employed and generally will not honor warranties unless this is done. Last line filters just before the final delivery pipe are strongly recommended in addition to any other filtration system due to fine particle settlement and accidental insertion of particles in the intermediate lines. Drip and subsurface drip irrigation is used almost exclusively when using recycled municipal waste water.
Regulations typically do not permit spraying water through the air that has not been fully treated to potable water standards. Want more? Advanced embedding details, examples, and help!
