  1. Sir how you Get that 120N 60P 60K, is it 2:1:1 Ratio or any other, source of that value for a particular area. If any link over that please share

  2. DAP = 50×10046
    = 108.6 kg per ha
    If 2 ha given area is = 108.6×2
    217.2 kg DAP release P
    DAP release 217.2P×18 N/100
    = 39.06 kg N release through DAP
    Urea N = 100-39.06 =60.4 kg N
    Formula apply 60.4×100/46
    131.6 kg per ha
    131.6×2 ha area = 262.6N kg
    MOP K= 1.66×50 = 83 kg
    83×2 = 166 kg
    Final = N 262.6kg
    P 217.2 kg
    K 166 kg
    If I am wrong please send correct calculation

  3. Please tell me if I make it at home, with useing state fartilizer, can it work like composite fartilizer. With the help of below ratio.
    N. P. K.
    10.26.26 we need (0.217+ 1.625+0.433)
    28.28.00 we need (0.610 + 1.75 + 000)
    18.46.00 we need (0.390 + 2.875 +000)
    14.35.14 we need( 0.304 + 2.180+0.233).

    0.304 means 304gm
    2.180 means 2 kg 180 gm. Thank you.
