Benefits of
frequent fertigation
Pivots have emerged as an alternative to traditional fertilisation, enabling the simultaneous application of fertilisers and irrigation water without the need to use other, more invasive methods on the crop.
The addition of chemicals to the irrigation water thus enables simple improvements to be made to the crop, such as:
Adjusting the pH of irrigation water, adding nutrients (fertigation), improving soil properties, applying pesticides (chemigation).
Rational use of fertilisers
- Better control
- Improved fertilisation efficiency
- Increased crop yield
- Nutrients can be tailored to the actual needs of the crops: plant development, climate, etc.
Reduced production costs
- No additional labour is needed for fertiliser application
- Reduction in the quantity of fertilisers used
- Fertiliser can be applied as often as necessary, without increasing operating costs
- All irrigation days can be used for fertigation
Minimal impact on the crop
- Machinery traffic is eliminated
- Reduced salinity peaks in the soil
Lower environmental footprint
- Reduced use of fertilisers
- Reduced losses due to soil leaching
- Lower fuel consumption and CO2 emissions
To apply these chemicals, precise injection equipment such as an electric dosing pump is required. This equipment allows applications to be automated to make this process more efficient.

Solutions
For the application of fertilisers and other chemicals through irrigation water using systems with variable water flow rates or zoned irrigation systems, in which we have a constant flow rate, the equipment used to prepare and inject the solution is manually operated from the pivot's control panel, which injects an even amount of the product.
Recommended products for manual dosing
In this type of system, the equipment has a variable water flow rate or performs zoned irrigation. The system includes a flow meter that sends information about the flow rate to an advanced-control pump that adjusts the application of fertilisers and other chemicals according to the irrigation flow rate.

How can you use 100% of the surface area of a field?
For more advanced systems where a higher level of technology or more efficient use of the crop and soil is required, it is advisable to install a system with a variable flow rate and surface area.
This means pivots with corners or end guns. These systems adjust the flow rate as required for corner areas, i.e. they increase the flow rate depending on the area in which the pivot is located.
In such cases, to ensure a rational use of fertilisers, the best option is to install advanced-control equipment that will adjust the application of these chemicals, thus reducing the amount of product applied by an average of 20%.
One example of advanced-control equipment is the Dostec AC dosing pump.
