Drip Irrigation process is now a longtime approach to irrigation in water scarce parts however it is usually gaining value in water plentiful components. during this expertise, the cropped box is irrigated within the shut neighborhood of root area of crop. It reduces water loss happening via evaporation, conveyance and distribution. hence excessive water use potency should be completed.

Acid fertilizers can corrode metallic components of the irrigation system. • The immersed fertilizers can raise the water pH and trigger the precipitation of insoluble salts that will clog the emitters and the filtration system. • Operation and maintenance requires skilled manpower. • Health hazard exists if the irrigation water system is connected to the drinking water supply network. Failure in the water supply may cause the back flow of water containing fertilizers into the drinking water system.

We are concerned here with drip irrigation systems so the sampling must be done accordingly. The place and depth of soil sampling relative to the drippers is a sensitive issue of particular importance. Usually it is recommended to get samples beneath the dripper, between the drippers and between the lateral pipes. In order to estimate the nutrient supplying capacity of a soil, apart from soil analysis, the parameters such as depth of the crop rooting system, percentage of soil occupied by the COMPONENTS OF DRIP IRRIGATION SYSTEMS 35 root system under different irrigation systems, and soil bulk density are needed.
