How to Fertilize with Drip Irrigation?
The method of fertilization with drip irrigation (fertigation) is an advanced application in modern agriculture aimed at meeting water and nutrient needs in the most effective way. This system, based on delivering water and fertilizer directly to the plant in agricultural lands, provides a great advantage to farmers. Fertilization with drip irrigation prevents unnecessary losses by providing only as much water and nutrient elements as needed for nutrition. If we look at how this system works;
What Should Be Considered When Fertilizing with Drip Irrigation?
In the fertigation method, it is extremely important to act according to the information given below so that fertilizers and other chemicals can be applied effectively and correctly.
- Fertilizers that do not dissolve completely in water (such as urea and ammonium sulfate) are harmful to the drip irrigation system.
- Before fertilizer solution is given to the irrigation system, only water should be given until the working pressure is reached.
- Although some plant nutrients dissolve completely in water, they may react with other nutrients in the system or with ions present in high amounts such as calcium or magnesium in the irrigation water to form precipitates. Therefore, knowing the quality of the irrigation water and the miscibility properties of the fertilizers is extremely important for success in application.
- If the irrigation water is calcareous, phosphorus fertilizer should be applied to the soil as a base fertilizer.
- Fertilizers containing phosphate and fertilizers containing calcium should not be used together.
- After fertilization is completed, the drip irrigation system should continue to be operated with only water for 10-15 minutes.
- The pH level of the irrigation water used in fertigation should be between 5.5 and 6.5. To maintain this range, acids such as phosphoric acid, nitric acid, sulfuric acid, or hydrochloric acid can be used.
- In acid use, acid should be added to water, but water should not be added to acid.
- Never mix an acid or acidic fertilizer with chlorine. Acid and chlorine should not be stored in the same room.
- A concentrated fertilizer solution should not be mixed with another concentrated fertilizer solution.
- A compound containing calcium and a compound containing sulfate should not be mixed. Because, as a result, an insoluble gypsum mixture will form.
- At the end of the irrigation season, the irrigation system should be cleaned by operating it with 0.3% Nitric Acid.
- Some fertilizer combinations of high concentrations can cause crystallization and clogging of pipes.
⚠️Concentrations causing crystallization
- Calcium nitrate + ammonium sulfate = calcium sulfate
- Calcium nitrate + potassium sulfate = calcium sulfate
- MKP + calcium phosphate = calcium phosphate
- MAP + calcium nitrate = calcium phosphate
- Phosphoric acid + calcium nitrate = calcium phosphate
What are the Advantages of Fertilization with Drip Irrigation?
- Since fertilizers are given to the root zone of the plant along with water, extra fertilizer is not given to places where root development does not occur.
- Due to the application of less fertilizer and water with fertigation, both production costs and groundwater pollution are reduced.
- It provides energy and labor savings.
- The yield and quality of the product increase.
- The exposure of applicators to the applied chemicals is reduced.
- It provides the opportunity to fertilize when necessary without bringing machinery into the field.
- By increasing the availability of saline nutrient elements, it raises the fertilizer efficiency.
- It reduces the negative effect of wastewater.
- Fertilizer losses due to leaching are minimized.
- Since the upper parts of the plants are not wetted, it becomes easier to fight diseases.
- If desired, appropriate agricultural pesticides and other chemicals can also be applied at the same time.
- It is suitable for automation.
