60 kg/ha nitrogen (top dressing)
60 kg/ha P205 (in planting hole).
60 kg/ha K20. How much sulphate of ammonia (20%) would be required per hectare? How much double super-phosphate (40%) P2O5would be required per hectare? How much muriate of potash (50% K20) would be required per hectare?

Answer/Solution

Sulphate of ammonia (SA) which gives 60kg/ha N
60/20 x 100 = 300 kg SA

Double super phosphate (40% P2O5)which gives 60kg/ha P205
60/12 x 100 = 150 kg DSP

Muriate of potash (60% K20) which gives 60kg/hK2O
=60/60 x 100 = 100 kg muriate of potash
