60 kg N 20 kg P205 30 kg K 20 Land size = 10 ha

i) Urea = 46kgN — 100kg Urea;

= 60 x100/46 x 10 ha;

= 1304.305 kg of urea;

ii) SSP (20% P205 ) 20 kgN — 100kg Urea =20 x100/20 x 10 ha = 1000 kg of SSP;

iii) Muriate of Potash (50% K2O) 50 kg K2O — 100kg

Muriate Potash =30 x100/50 x 10 ha = 60 kg/ha

= 60 x 10 = 600 Muriate of Potash;
