3 days a fair bit better than 6.
Don't get to hung up on days per shift, grass growth isn't uniform so it will vary through the season.
Much better to be guided by pre and post grazing covers imo.
And have a back up plan for times when there's to much grass or to little!
The N costs the same but we're hoping to apply at 25% rate, humate and extra application cost puts foliar to around 35/40% of the cost of solid.
If it works.
We've been playing around with it for 3 years and certainly encouraged, current N price has hurried us along and we now aim to use it...
Hopefully that works.
I'm sure you're not after farm trials but we managed 8 ton in SB...
