The Nagaon Paper Mill, a public sector pulp and paper mill, a unit of Hindustan Paper Corporation Limited, is located at
Jagiroad, Morigaon district, Assam and generates about 448 tonnes
of lime sludge per day as solid waste. Instead of marketed lime,
lime sludge waste of the paper mill can be used to optimize the pH of the agricultural soil. Keeping this in mind, the present investigation was carried out to study the effect of lime sludge on growth and production of some agricultural crops like mustard, pea and rice as well as physicochemical properties of the soil.
