How much AN used on Winter Wheat ?

[student101]

Im a third year student at a well known Agri uni and looking for some info, I`m doing an assignment on carbon footprints and have the following question for winter wheat growers.

“What is the total quantity of ammonium nitrate (AN) fertiliser you apply over the 12 month period on winter wheat kg/ha – stubble to stubble.? no doubt it will vary so I will average replies.

Also what is the percentage of nitrogen in the product you use.?

Thanks in advance.

Our feed wheat's have 220kg/ha N. The product we use is 27% AN so total product applied per ha is 814kg/ha.

My wheat gets 240 kg/ha N (shallow soils). in Pure 34.5% AN that = 696 kg/ha AN but some will go on as a N+S compound 26% N 35% SO3 which is AN based.

I use urea 46% at 220 kg n per ha in 2015 producing grain at 9.5 % protein to 11.5 % protein

I plant a tree every year , to balance up.

Read RB209. Google fertiliser ranges from growhow or whatever they are called now.

First wheats after beans, or flush crops usually 200kg N, second and subseqent wheats 240kg. Usually applied as kg/ha of 26n 35s with the rest straight 33.5%N

Hi
We put 220. Kg N/ha on second wheats and 190 kg N/ha on first wheats after OSR.
First dollop is nearly always Urea 46% N
Subsequent dollops are nearly always Nitram 34.5% N. or LithAN if it looks like "good" stuff.

To complicate matters " my man" put fertilizer on in Units/Acre..... So it's a bugg*r of a job trying to work out how many Kg N/ha for GateKeeper.... Lol

Milling wheat gets:

280kg/ha Piamon (33N, 30SO3)
300kg/ha urea 46%
200kg/ha lithan 34.5%

First dollop as soon as we can travel without making a mess. 2nd dollop about a month later. Total about 300kg/ha. Last dollop as late dressing for protein.

Feed wheats get 300kg of piamon, then 2 x 200kg/ha urea.

All these will be tweeked depending on previous crop, soil sampling etc and how the crop looks.

That will bugger up my calculations and make twice the work

 

[franklin]

make twice the work

That's what they want - keep the clip-board weilding graduates in work.

True , but Im trying to do it as quickly and as easily as possible , normal for students

So would it be fair to say 250kg AN at 33.5% , per hectare per annum would be "normal" ?

200 kg/ha for heavy land feed wheat
220 - 240 for lighter land feed wheat
Add 40 kg/ha extra for milling wheats to boost protein.

Thanks chaps, no doubt I`ll be pestering you for more info in the future...or a job

4.5 to 5 cwt to the acre, giving 160 to 170 units of N.
There, that's stumped you!

 

[student101]

Im an older student and remember unloading 20 ton trailers of cwt sacks by hand regularly , the units bit has stumped me though.

3 to 4 cwt an acre

Sorry . You'd better stick to metric.
Units are simple for us old school guys. For instance if you were putting on two bags to the acre of nitram 34.5%, it would mean you had put on 70 units/acre .
Gets frowned on here though !
I wonder if we came out of Europe, whether we could go back to it?
