Water logging and salinity: Issues and challenges in restoring the land resource
Author(s): Dr. Ved Parkash, Dr. Chander Mohan
Abstract: One third of the agriculture lands are facing the problem of salinity and water logging. The water table has risen to variable depths in different regions of Haryana including Hisar, Sirsa, Rohtak, Jhajjar and some villages of district Charkhi Dadri. It has transformed a large component of land barren i.e. unfit for agriculture purpose. Agricultural ecosystems are man management ecosystems for growing crops and fodder for the livestock. In some of the villages of the study area, mustard, bajra, rice and wheat are the major crops. But during last few years the practice of growing rice is increased several folds. The reasons are reciprocal i.e increased canal based irrigation and seepage of water from earthen canals has raised the water levels. It has inhibited the growth of traditional crops and favoured the cultivation of wheat and rice and other water loving weeds. Further due to more economic gain, the farmers adopted the practice of growing wheat and rice as choice and not as compulsion. These two crops need excessive irrigation. As a consequence, some low lying areas are severely suffered from water logging problem. Extensive irrigation in these villages has resulted in water logging and salinity of lands. In the survey, it is found that underlying strata below the A- horizon of soil in study area is having clay layer which prevented the natural drainage of surface waters. Further, there is sufficient recharge of underground water from canals and monsoon waters. In the present paper it tried to find out various approaches useful in managing water salinity and reclamation of water logged lands. It is also aimed at suggesting a suitable model for efficient water drainage. The agroforestry regions are found less affected by water logging and thus less salinity, so such type of practices can be adopted to tackle the problem of water logging and increasing salinity.
