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…

Agree with everything Mark said. There is some mineralisation of N from organic matter after the break, so adding extra N too early will have less benefit than once the plants are actively growing. 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…

My soil tests are showing a severe lack of potassium (no shocks there!) – saying I need to apply 80kg/Ha. Question is – how do I improve potassium levels in my paddocks without using NPK / chemical fertilisers?
