Would it be possible to use only foliar in order to make the most of expensive nitrogen? As I understand it is way more efficient but is it possible supply all this way? Looking to apply 170 kg N/ha.
Thanks
Nope, IMO Still need a decent amount of soil applied N to build the biomass, if can apply 120-160 kg N then you use the foliar N to replace the final 30-40 kg N.Would it be possible to use only foliar in order to make the most of expensive nitrogen?

Good grief yes, been there etc.Have to be careful with straight N20 urea applied foliar through conventional nozzles as scorch risk very high!
agree entirely........I know a few who have historically made their own N20 for soil applied applications through dribble bars so can be applied to soil, however I wouldn't want to be applying to the leaf regularly through flat fan nozzles!Good grief yes, been there etc.
Presumably N20 that misses foliage and hits the soil isn't wasted. With true foliar products you'd need a full canopy to intercept it which may not happen until April-ish.
