Fertigation is application of fertilizers in an optimum amount after combining it with irrigation water. Fertigation can be achieved through fertilizer tank, venturi system, injector pump, Non-Electric Proportional Liquid Dispenser (NEPLD) and automated system. Fertigation helps in frequent supply of nutrients and reduces fluctuation of nutrient concentration in soil. Fertigation facilitates optimum application of fertilizers with efficient utilization. Uniform application of fertilizer throughout the irrigated soil volume can be achieved through fertigation. Nutrients can be applied to the soil when soil or crop conditions would otherwise prohibit entry into the field with conventional equipment.
