Have done 12 months forward contract forward for blend, which at the time looked gamble, it doesn't now but will only know at end of contract if I was clever/lucky.

If it of interest to anyone,
Hi guys,
I’m relatively new to the topic. we’re looking into foliar feeding this year (trying to counteract the price increase) using granular fertiliser.
Is there any guidance re dilution rates for grass, kg/100 litre. As far as I can understand there is a sweet spot between too diluted (less efficient delivery) and too concentrated causing burn. I’ve also the same question re the quantity of humic acid per kg of granular urea.
finally, is it purely urea, will foliar application be as effective with CAN.
thanks in advance

There is a fair amount of variation in regard to rates as depends what you want to achieve, what your rates have been in the past etc. wouldn't advise dropping by more than 40% of your typical granular application in year 1 for example. It is urea for foliar, unless you go down the foliar specific type product route, I have read a paper but not trialed in practice that applying AN in liquid form gives a significantly better response. Not sure where in the country you are but feel free to PM me.Hi guys,

Very interesting!
Where do you get dollar feeds and can you just spray them on with a normal sprayer?
Yes we've used a normal sprayer.
There are getting to be a lot of foliar products on the market. I suspect some are better than others....
We mostly melt granular urea but also but some foliar specific products from yara and Aiva

How come the urea doesn’t all just evaporate or does the plant take it up quick as it’s on its leaves?
And how long after application can you graze it?
Never hot enough here for that
If the can spread urea in aus I think I'll be OK.
And yes it's in the plant very quickly.
Not seen a definitive answer on the grazing

So why aren’t more doing it, especially with bagged prices doing what they’ve done?Never hot enough here for that

You using a tow and fert machine for the melted urea?
Normal sprayer wouldn't handle it or will it?

If I was a betting man I’d bet that you’ll buy a tow and fert, would suit your system?
It's of great interest until you get to the price tag.
Non about 2nd hand. And keen to let @vantage do a year before commiting 40k to some plastic

Can you tow it behind a pick up/quad bike or do you need a tractor? I’ve only looked them up very briefly. You’ll bite the bullet at some point.
Need 3 if quad driven

I'm hoping to have a go later this year. I have 3 X 2500 litre old ice bank tanks. I've also already got one of these which should do the job.
I also bought a fairly tidy 24m sprayer last year for £3k.

Apply with humic/fulvic acid helps to stabilise the N. Also additional products you can add to stop it drying out so quick in warm weather to give time for absorption. Technically you could graze within a couple of days, realistically why would you as you've applied N to increase your leaf area to increase photosynthesis so you want to get the benefit. Typically targeting middle 1/3 of the grazing wedge to get the balance between enough leaf to make the foliar effective and the faster part of the growth curve.

@Beef farmer guessing your comment fairly tongue in cheek but Tow and Fert is little more than a bit of plastic to be fair, stainless steel pump and booms and chassis is very well built, a lot of R and D has gone into it.
If your solely looking to do urea it is possible with the equipment @Cows 'n grass has listed. I would question the longevity of pump seals and bodies but great to try it out. I'd also make sure there is some sort of filtration before your crop sprayer as it is surprising how much grit comes in urea.
If taking a longer term outlook the versatility of what the Tow and Fert can handle is its big attraction as plant nutrition is a lot more than just N. For disclosure I have owned one since May 2020.
Booms and multiple cow paddocks are gonna be a PIA
But interested in how you get on
