Many students are asking about ENR (It's Electro neutrality ratio) Earlier salt affected soils categorised into saline and sodic based on electro neutrality ratio / If the pH of the soil is less than 8.2 and ENR is less than which is Saline soil and similarly if the ENR is more than one and pH of the soil is more than 8.2 that soil considered as Sodic soil..
