The Central Soil Salinity Research Institute (CSSRI) is an agricultural research institution located in Karnal, in the Indian state of Haryana. It functions under the Indian Council of Agricultural Research (ICAR) and is dedicated to research on the management and reclamation of salt-affected soils and the use of poor-quality water for agriculture.

| Type | Agricultural research institute |

| Focus | Salt-affected soils, sodic and saline land reclamation, saline water management |
CSSRI conducts basic, strategic and applied research on problems associated with salinity, sodicity, waterlogging and the productive use of saline and alkali groundwater in irrigated and rainfed agriculture. The institute develops crop varieties tolerant to salt stress, soil reclamation technologies such as gypsum application for sodic soils, sub-surface drainage for waterlogged saline lands, and agro-forestry systems suited to degraded lands.
Salt-affected lands form a significant share of India's degraded soils, particularly in the Indo-Gangetic Plain, coastal tracts and parts of the arid west. CSSRI was established to address these problems through scientific research, and to support national programmes for the reclamation of usar (alkali) lands and saline soils. The headquarters at Karnal lies in the alluvial plains of Haryana, a region historically affected by sodicity and rising water tables in canal-irrigated tracts.
In addition to its main campus at Karnal, the institute operates regional research stations to cover diverse agro-ecologies of salt-affected lands in India. These include centres focused on:
CSSRI also coordinates the All India Coordinated Research Project on Management of Salt-Affected Soils and Use of Saline Water in Agriculture, which links state agricultural universities and ICAR institutes engaged in similar work.
The institute's recommendations on gypsum-based reclamation of sodic soils, sub-surface drainage in waterlogged areas, and the cultivation of salt-tolerant rice and wheat varieties have contributed to bringing degraded lands back into productive use. Its work supports both farmer livelihoods and national objectives of food security and sustainable land management.
