4 hundred weight of 20 10 10 to acre, how many kilos of nitrogen is that to the ha ?
why ? please dont worry yourself with such nonsense4 hundred weight of 20 10 10 to acre, how many kilos of nitrogen is that to the ha ?
Can I see the workings please?By a quick bit of mental arithmetic...
74 kg
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 lolwhy ? please dont worry yourself with such nonsense
That makes sense.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
