why ? please dont worry yourself with such nonsense

 

[GTB]

80 units of N per acre is 200 units per ha or thereabouts. But no idea how you convert to kg???

 

[GTB]

By a quick bit of mental arithmetic...
74 kg

Can I see the workings please?

 

[bobk]

100 kg/ha

why ? please dont worry yourself with such nonsense

Fertiliser plan that has to be filled out before june, has to be kept on farm for inspection, i like to keep the job right as much as i dont like the paper work side, been at most of the morning my head is lost in numbers, i have number dyslexia as well nightmare but i get there lol

 

[sodbuster]

200

 

[ollandroverman]

448lb
2.2 lb to a kg so 203.64kg
203.64 times by 2.47 acres to hectare is 502.98 kg

Edited to correct my earlier mental arithmetic inaccuracy.

Now who do i belive,,,,,,,,,,,,,,,,, eny miny mo

4 x 125 =500
500 x 0.2 = 100kg/ha

 

[Shutesy]

I make it 98.8kg N per ha.
1 cwt = 50kg so 4 cwt = 200kg fert per acre
200kg x 2.47 = 494 kg/ha of fert
20% of 494 = 98.8kg N/ha
So basically 100kg/ha N

 

[7610 super q]

4 x 20 = 80 units N / acre. X by 1.25 = 100 kg/ ha ?

 

[DieselRob]

In round numbers I understand it as 1cwt is 125kg/ha so 4cwt is 500kg/ha multiply it by 0.2 (for the 20% of the product that is the N) and I get 100kg N per hectare.

That makes sense.

 

[Chae1]

As I understand it for every 100 kg of 20.10.10 you are putting on 20kg N.

4 hundred weight. Is 500kg/ha.

So 80 units per acre.

 

[bobk]

Units to the acre x 1.25 = kg / ha

 

[ollandroverman]

Ah feck
Mental brain fart....
203.64g times 2.47 acres to a hectare!
Should be 502.98kg hectare

 

[Stewartry hill]

My fert plan is in unit's acre if it needs converting department can do it strangely it's just the same as last year

 

[ollandroverman]

My excuse for my poor performance is I am more used to converting metric to imperial.
