Technology of planting halophytes (Dixie grass) for restoring highly saline soil

Dixie grass ( Sporobolus virginicus) is a halophyte plant. The objective of growing is to increase suitable land use change for farmers and to prevent saline soil distribution. Dixie grass can be used as fodder. Land Development Department has been trying to propagate Dixie grass to cover the area severely affected by salt. Growing halophytic grasses (Dixie grass) aims to make farmers able to utilize land and to decrease distribution of areas with saline soil. Dixie grass can be used as a plant, fodder for cattle. Land  Development  Department  has  brought  the  technology  of  planting  halophytes  for restoring areas with highly saline soil to be used in the area of Mr. Chalong Munkarn residing at the address: 6, Moo 8, Kud Jok sub-district, Bua Yai district, Nakhon Ratchasima province. The area is a plateau with the steep slope of 0-2%. The soil has an electrical conductivity of more than 16  dS/m.  The area  has  soil  with  high  salinity and  a  semi-arid-climate.  The  amount  of  rainfall accounts for 751-1,000 mm. per year. Most farmers grow crops based solely on rainwater. This is due  to  the  fact  that  the  area  has  a  condition  of  highly saline  soil,  making  farmers  obtain  low productivity. Halophytes are plants which grow and give good yields at the level of high salinity especially for Dixie grass (Sporobolus virginicus) with the ability to survive accounting for 100% in the salinity of 40 ppt (NaCl). Dixie grass has adapted itself to have smaller vascular bundles  and has adjusted the osmotic pressure. There is salt excretion at the glands on the leaves. Planting halophytes is to utilize areas with saline soil and to grow cover crops. This helps control  moisture at the soil surface and prevent salt accumulation at the soil surface. This also includes being  fodder for farmers conducting livestock farming whereby there is excreted salt on the leaves of the grass which cows like to eat them. The grass has qualities similar to other fodder plants.
