Buy the plate meter now, don't worry about the grant, have a look on eBay, borrow one the day someone else isn't using, anything to get your hands on one!
Once a week minimum I would say, if you have rain or a change in the weather this time of year things change really quickly.
It's the sort of thing that will pay for itself really quick without you noticing, as long as you use it!
I reckon it took me 3 seasons to get a decent handle on it, still bugger it up every so often now.
Plus the discipline of doing it makes you look at your fields regularly and it's a nice walk around with the dog.
Good luck!
