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 In ammonia synthesis (N₂ + 3H₂ = 2NH₃), there is a decrease in total volume, hence to get high equilibrium conversion, the reaction should be carried out at High pressure Very high temperature Low pressure Atmospheric pressure; as the pressure has no effect on conversion High pressure Very high temperature Low pressure Atmospheric pressure; as the pressure has no effect on conversion ANSWER DOWNLOAD EXAMIANS APP
