    Ability to apply small amounts of nitrogen more often.

    Less chance of volatisation and leaching.

  • USES

    Flowfert N is designed for use through irrigation systems. Centre pivot and lateral move systems have the highest irrigation efficiency and are most suited to fertigation.

    You can use Flowfert N at a similar time as when you would use Urea. The spreading of solid Urea will still be suitable in the early spring and late autumn when it is undesirable to irrigate.


    Flowfert N is pumped from a 30,000L tank and injected into the irrigation pipes. 1-30 units of nitrogen (equivalent to 1-30kg N/ha) are applied, depending on pivot speed and pump size.

    Soil testing and fertiliser plans are available to ensure you use the right product at the correct rate.

  • WHY USE?

    With Flowfert N you can apply nitrogen when it suits your farm’s feed demand and crop requirements. Irrigated crop or pasture will receive water and nitrogen at the same time, allowing it to use both for growth.

    Applying small amounts daily to the root zone is ideal for plants and will result in a more even growth curve. The plants are able to take up more of what has been applied, leaving less to potentially be lost to the atmosphere or through leaching.


    Ravensdown offers two forms of Flowfert containing nitrogen, Flowfert-N (Liquid), and Flowfert Urea (Solid). Both result in an 18% nitrogen solution suitable for fertigation or spraying.

    Flowfert N (Liquid) is delivered as an 18% nitrogen solution and is made in Hornby (Christchurch) suiting farmers close to the Hornby Works. The liquid is delivered in a bladder in 12,500 litre drops. Liquid Flowfert N is also available from consignment stores in Methven, Otautau and Winton.

    Flowert Urea (Solid) is made on farm to an 18% Nitrogen solution. 9,800 kgs of Urea is transported in a bulk truck and blown into a 30,000l tank. An automated process adds water and stirs the solution to make 25,000 litres of an 18% strength nitrogen solution all in about 24 hours.
