Fertigation |fertilizers for  Fertigation | Drip fertigation system 

✓ Fertilizers are usually applied by ploughing, spraying or spraying (soluble fertilizers).  Fertilization is the application of fertilizer to the crop through irrigation water. 

 ✓ In this method the water required for cultivation and the nutrients required for the crops are simultaneously supplied to the plants in the form of micro-irrigation in parallel. 

✓  Fertigation method not only increases crop yield but also minimizes adverse effects on the environment.  

Currently the Fertigation method is widely used in a wide variety of crops and in a wide variety of soil conditions.  

 Key Fertigation Method Key Ownership:-  .

✓ Fertigation takes into account various aspects of crop ownership and determines at what stage and in what dosage nutrients should be released accordingly.  


Some important factors that affect fertilization are:

 ✓ crop selection (type, crop growth stage, plant density in a given area, crop nutrient uptake, harvest duration).  


✓ Cultivation method (normal cultivation, cultivation in a greenhouse). 

 ✓ Geophysical and chemical properties (soil nature, salinity index, hydrogen index, gluten percentage, organic carbon).  Water quality and weather conditions. 


 ✓ As mentioned above Fertigation management is affected by a variety of factors.  

So consider the technical aspects suggested below when making a plan to provide nutrients to the crops by fertigation:-  

1. Fertilizer tank device should be used in medium to deep wetlands.  Fertilizer injector device should be used in light soils as well.

2. Providing nutrients through daily fertigation is highly beneficial.  If this is not possible then fertilization should be done at least twice a week.  

3. Select the right fertilizer according to the nutrient requirements of the crop.  The fertilizer of choice should provide nutrients as well as modify the water hydrogen index if necessary. 

 4. The selected chemical fertilizer should be suitable for cultivation water quality.  (Otherwise sediments will form and the drippers will close).  

5. Farmers should keep in mind that high doses of calcium, magnesium sulphate, iron or manganese in the irrigated water can react with the fertilizer and reduce the efficiency of the fertilizer. 

 6. Combined with common urea, white matter muriate of potash and water soluble complex fertilizers to meet the nitrogen, phosphorus and potash requirements of the crop.

  7. Different chemical fertilizers mixed in the same tank should have the nature of mixing easily with each other.  Liquid fertilizers are also available in the market.  But these are expensive so they are used in high value horticultural crops.  

8. The daily dose should be calculated in such a way that all the recommended nutrients for the crop are provided during the entire harvest season. 

 9. When adding chemical fertilizers in liquid or powder form, care should be taken not to exceed 70% of the tank size.  

10. fertigation period should be an integral part of cultivating water supply period.  The duration of fertilization should always be less than the duration of irrigation water supply.

 11.Drip system should be run for a while before starting the fertigation process.  This causes water to be released at equal pressure throughout the farm. 

 12. Run the drip system for a while and start fertigation only when the water pressure is constant.  This allows the drippers away from the system to deliver water and nutrients to the plants at equal pressure.  

13. The drip system should be run for a short period of time after fertigation.  This washes away the residual nutrient residue in the pipes and drippers.  If water is pumped for a longer period of time, the nutrients near the plant roots will seep into the inner layers of the soil.  

Benefits of fertigation: 

✓ Significantly increases nutrient utilization efficiency.  Nutrients are not wasted.

 ✓  The crop will receive the desired dose.  Availability of nutrients in the desired dose and at the required stages for the crop. 

 ✓ Fertigation can overcome the risk of nutrients leaching into the soil, evaporating as well as being converted into unavailable nutrients.

✓ Fertilizer use will be reduced by 15 to 40 per cent as well as labor requirement by 10 to 15 per cent.

 ✓ Fertigation doubles the fertilizer application efficiency compared to traditional methods such as spraying and planting.  

✓ Fertigation is a very convenient method in sloping fields as well as other problematic lands.

✓ Fertigation, above all, maintains the ecological balance.  Crop yields are likely to increase by about 30 to 40 percent. 



  1. Fertilizers used in fertigation method should be water soluble in nature.  Otherwise the fertilizer sediment will close the dripper holes.  


 2. Fertilizer method can be applied in powder or liquid form.  


 3. Choose non-chloride fertilizers to achieve good quality and yields.
