Fertigation means fertilizer application through irrigation by the drip system, this method permits even distribution of fertilizer solution to the crops. This improves the growth and the yield of the crops because nutrients is always available through liquid fertilizers to individual plants.
Importance of Fertigation
Fertilizer used in fertigation are urea, potash, mono ammonium phosphate (Nitrogen and Phosphorus), poly feed (Nitrogen, Phosphorus and Potassium), Multi K (Nitrogen and Potassium), Potassium sulphate (Potassium and Sulphur) and highly water soluble fertilizers are available for applying through fertigation.
Equipments used in fertigation are:
– Fertilizer pump: is a special pump that gives pressure to the fertilizer solution that has been prepared in the tank.
-Fertilizer tank: the container where chemicals are diluted, connected to the pump which pressurize the solution in the tank, supplied to the irrigation pipes and delivered to individual plant through the drip systems.
-Ventury: is a vaccumwhich is required to suck fertilizer solution from an open container into the water flow.
Rain fed crops cannot produce food sustainably, water shortage worldwide and urbanization has necessitated the need for improving farming methods like fertigation which is suitable for annual crops, horticultural crops, and tree plantations.
Fertigation, irrigation and chemigation has been efficiently used in food production on small and large scale farming all over the world.
