Fertiliser Technology Excessive use of chemical fertilisers causes shrivelling of the roots and wilting of the plant, because the Soil becomes too acidic Osmotic pressure of the soil water becomes less than that of the plant sap Soil becomes too alkaline Osmotic pressure of the soil water becomes higher than that of the plant sap Soil becomes too acidic Osmotic pressure of the soil water becomes less than that of the plant sap Soil becomes too alkaline Osmotic pressure of the soil water becomes higher than that of the plant sap ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Nitric acid is produced on commercial scale in a fertiliser plant by CaNO₃ + H₂SO₄ reaction Oxidation of ammonia None of these Passing air through high voltage electric arc CaNO₃ + H₂SO₄ reaction Oxidation of ammonia None of these Passing air through high voltage electric arc ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Multistage operation (as in the case of catalytic oxidation of SO₂) is not carried out for NH₃ synthesis, because of Chances of entrainment and disturbance of catalyst bed Higher pumping cost Comparatively higher pressure drop High cost of the high pressure vessel used for the reactor Chances of entrainment and disturbance of catalyst bed Higher pumping cost Comparatively higher pressure drop High cost of the high pressure vessel used for the reactor ANSWER DOWNLOAD EXAMIANS APP
