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 higher than that of the plant sap Soil becomes too alkaline Soil becomes too acidic Osmotic pressure of the soil water becomes less than that of the plant sap Osmotic pressure of the soil water becomes higher than that of the plant sap Soil becomes too alkaline Soil becomes too acidic Osmotic pressure of the soil water becomes less than that of the plant sap ANSWER DOWNLOAD EXAMIANS APP
