28% Foliar Nitrogen – Liquid Foliar Nitrogen Fertiliser.
Unique Amide Nitrogen (NH2) formulation designed to provide effective crop uptake whilst maximising crop safety.
The amide (NH2) formulation breaks down slowly to enable faster plant uptake compared to nitrate forms of N, resulting in greater Nitrogen Use Efficiency compared to traditional nitrogen fertilisers.
N28 is a useful tool where growers need to supply additional nitrogen to crops where N availability may be limited.
Due to the increase in NUE, Foliar N in some situations can displace the need for 40kgs bagged nitrogen.

Backed By Research
Trials Data:
- Margin Over Input Costs (MOIC)
- Our trials indicate that 40 kgs of bagged nitrogen are replaced with 20 liters of Efficient N28 – there is no impact on yield or income per ha.
