A farmer was advised to apply 150kg of C.A.N to maize field . Calculate the amount of nitrogen applied per hectare if C.A.N contains 21%. N The recommended rate of top dressing maize is 200kgN per hectare. If CAN contains 25% N, how many 50 kg bags of CAN should a farmer apply to 0.25ha of maize crop to achieve the above rate  A farmer was advised to apply 40kg/ha P2O5 in planting holes, 60kg/ha Nitrogen in top dressing and 60kg/ha K2O in a Maize field. The available fertilizers were Sulphate of ammonia 20% N, DSP 20% P2O5 and muriate of potash 50% K2O.Calculate how much Sulphate of ammonia and muriate of potash would be required in one hectare of land. (Show your working.) A farmer was advised to apply 100 kg/ha of a compound fertilizer 20-15-10. How much potassium Pentoxide will he apply in 0.5ha farm? ​After soil testing a farmer was asked to apply fertilizers as follows:50 kg/ha Nitrogen as top dressing, 60 kg/ha P2O5 at planting, 60 kg/ha K2O for top dressinga) Calculate how much calcium ammonium nitrate (20%N) would be required per hectare?100 kg CAN. Contain 20 kg N 50 kg N contains x 50 CAN = 250 kg CAN
b) Calculate how much double super phosphate 40% P2O5 would be required per hectare.100kg DSP contain 40kg P2O5 60kg P2O5 contained in x 60 DSP = 150 kg DSP
c) Calculate how much muriate of Potash50% K2O would be required per hectare.100kg of KCl contain 50 kg of K2O
60Kg K2O contained in =120 kg of KCl How much of the fertilizer 20:20:0 would be applied in a plot that requires 30kg P2O5.20kg P2O5 = 100kg fertilizer 30kg P2O5 = ?
30 x 100 20 = 150kg
