Applying foliar nitrogen timing
if your soil is low in N and you have used a fertiliser at seeding with a low % of N – when is the best time after plant emergence to apply foliar nitrogen?

Hey Will,
You can apply foliar nitrogen at any stage after emergence as the rates of N are quite low and what doesn’t get on the leaves ends up on the soil anyway.
However, plant uptake of any fraction that lands on a leaf is much more efficient and you get better bang for your buck if you wait until there is a decent amount of leaf matter before…

The cropping guys work on topping up 4-6 weeks post emergence for winter cereals. If you have kikuyu as a dominant pasture, extra N now with…
