question 1

if you have to apply 20 kg of N, 36 kg P,and 22 kg K on a 1 ha plot of land. How much of Urea (46% N), MOP (60% K₂O) and TSP (33% P₂O₅) is required for :

a) one hectare of this land

b) 35 m² plot on this land

c) 10 kg soil from this land

Assume 1 hectare of soil is 2 X 10⁶ kg of soil.  

Answer 1

Answer:

100kg urea gives 46kg N

100kg MOP gives 60kg K2O

100kg TSP gives 33kg P2O5
