Metric fertilizer settings

Be aware whether you are asking for the amount of product to spread or the actual quantity of N you wish to apply. These are two entirely different calculations. I suspect from the quantity stated that it is NOT the amount of product you are after but the amount of actual Nitrogen. Am I correct in that assumption?
They say 75kg n/ha just after that?

Well you can do 75x 100 /34.5 if you really want.

But it's kg of N (75) / concentration of fert/100 (34.5/100).

Once you know that it's simple to adjust for different requirements or concentrations.

Eg. 60kg n with 46% urea is 60/.46

I’ve always done it 75 / 34.5 x 100 = 217

It’s getting really complicated now 😂



i did not know my father had joined the forum. We have this conversation every year.

I’ve now succumbed and just say I’m putting a bag to the acre on and everyone’s happy!
My father pestered me to put more phosphate fertiliser on for 45 years until very near his death at 91. The fact that I fairly regularly test the soil and apply fertiliser as necessary and have done all the calculations and application since 1975, when I was 17, and that when asked how much should be applied he had no answer, made no odds. I had 40 years of him banging on incessantly for six months of every year about fertiliser when he didn’t have the slightest clue as to what crops actually needed. In latter years I never told him anything other than it was 20-10-10, but even that didn’t stop him criticising. I had long come to the conclusion that he wasn’t actually commenting on the fertiliser but me. Nothing I did was ever right with him.
The net result is that I miss my old cat more than I miss him. Rant over.

The Health and Safety Executive for Northern Ireland (HSENI) alongside the Farm Safety Partnership (FSP), has named new farm safety champions and commended the outstanding work on farm safety that has been carried out in the farming community in the last 20 years.

Two of these champions are Malcom Downey, retired principal inspector for the Agri/Food team in HSENI and Harry Sinclair, current chair of the Farm Safety Partnership and former president of the Ulster Farmers’ Union (UFU).

Improving farm safety is the key aim of HSENI’s and the FSP’s work and...
