Fertiliser Technology Excessive use of chemical fertilisers causes shrivelling of the roots and wilting of the plant, because the Osmotic pressure of the soil water becomes less than that of the plant sap Soil becomes too acidic Osmotic pressure of the soil water becomes higher than that of the plant sap Soil becomes too alkaline Osmotic pressure of the soil water becomes less than that of the plant sap Soil becomes too acidic Osmotic pressure of the soil water becomes higher than that of the plant sap Soil becomes too alkaline ANSWER DOWNLOAD EXAMIANS APP
Fertiliser Technology Though kinetics of ammonia synthesis dictates the use of low temperature for high equilibrium conversion, yet it is kept moderately high (550°C), because at low temperature Space velocity of gas is very low resulting in decreased conversion None of these Very high pressure is required resulting in costly pressure vessel Rate of reaction is very low Space velocity of gas is very low resulting in decreased conversion None of these Very high pressure is required resulting in costly pressure vessel Rate of reaction is very low ANSWER DOWNLOAD EXAMIANS APP
