Drip Irrigation approach is now a longtime approach to irrigation in water scarce parts however it can also be gaining value in water considerable components. during this expertise, the cropped box is irrigated within the shut region of root region of crop. It reduces water loss happening via evaporation, conveyance and distribution. consequently excessive water use potency may be completed.

Molybdenum (Mo): The ionic form of this nutritional element is MoO4—. This activates enzymes that are responsible for the reduction of nitrate NO3- to nitrite NO2-, therefore in molybdenum deficiency nitrate is accumulated in plant tissues. It is required by the rhizobium bacteria for nitrogen fixation in legume. Boron (B): The ionic form of this nutritional element is B4O7—. Boron activates certain enzymes and participates with sugars in producing complex compounds (lignine) that are responsible for the thickening and hardening of cell walls.

Lower fertilizer losses from the soil surface. • Better coordination of nutrient supply with the changing crop nutrient requirements during the growing cycle. • Higher application efficiency. • Full control and precise dosing of fertilizers in automatic and semi-automatic irrigation systems avoids the leaching of nutrients beneath the root zone. • Avoiding of mechanized fertilizer broadcast eliminates soil compaction and damage to the plants and the produce. • Fertigation contributes to labor saving and convenience in fertilizer application.

Media filter should be followed by a secondary screen filter to prevent carry over of contaminants following the backwashing process. Numbers designate the sand media filter used in most drip irrigation filters: number 8 and 11 are crushed granite, and numbers 16, 20, and 30 are silica sands. The mean granule size in microns for each media number is 46 AN INTRODUCTION TO DRIP IRRIGATION SYSTEM approximately 1900, 1000, 825, 550 and 340 for number 8, 11, 16, 20, and 30, respectively. When the water flows from top of the filter, it goes down through layered bed and flows out at the bottom of the filter.
