Planting a Halophyte (Sporobolus virginicus, "Dixie grass") to … [Thailand]
Planting a halophyte - Dixie grass (Sporobolus verginicus) - aims to increase the area of land usable by farmers and to prevent expansion of severely saline soils. Dixie grass can be utilised as cattle feed. The Land Development Department has been involved in developing and disseminating this technology.

2. Description of the SLM Approach
2.1 Short description of the Approach
The government promotes a halophyte (Dixie grass) to control severely salt-affected land, rehabilitate the ecosystem and prevent the spread of salt in soil - with the cooperation of land owners, livestock farmers, the local administration, the local government agency, Land Development Department researchers and with specialists/ technical advisors in various fields.
2.2 Detailed description of the Approach
Detailed description of the Approach:
The Ministry of Agriculture and Cooperatives through its Land Development Department (LDD) initiated a project on planting salt-tolerant trees and grasses on severely salt-affected land in the Northeast of Thailand in 1996. The project has facilitated the planting of a halophyte (a salt-loving plant), namely Sporobulus virginicus (Dixie grass) on salt-crusted and barren land. The main objectives of the approach has been to encourage land users to maximize their land area for farming, by preventing the formation of extensive severely saline soil. This is through planting Dixie grass as a cover crop to rehabilitate the land and ecosystem. The activities started with public meetings, then identifying severely salt-affected areas, and setting-up demonstration plots on farmers’ land to act as learning centers. There has also been communication with the local administration to call farmers’ meetings to develop detailed work plans and discuss strengths, weaknesses, opportunities, and threats of planting Dixie grass. The implementing activities consisted of 4 stages; PREPARATION was for seedling preparation, site selection of severely salt-affected soil and land preparation, public meetings and the establishment of the demonstration plot at Dan Chang Sub-district, Buayai District, Nakhon Ratchasima Province. COORDINATION included a joint meeting between farmers and researchers, joint monitoring & evaluation and follow-up and land users' decision-making. PLANTING started with selection of farmers joining the project, facilitating and training, a site visit to the model demonstration plot: this plot is the model for planting salt-tolerant trees and grasses on severely salt-affected land in the Northeast of Thailand. The final activity of SCALING-OUT occured when the land users/ farmers found that after 3 years of planting Dixie grass this barren land became covered by plants and much improved in biodiversity by the evidence of many varieties of wild grasses, flowers, dragonflies, small mammals and birds. Farmers could now grow rice and they used Dixie grass as feed for livestock. Moreover, and attractively, farmers were able to increase their incomes. Migration to big cities was reduced. The stakeholders were land owners, livestock farmers, the local administration, the local government agency, researchers and SLM specialists from LDD - and all worked together to mutual benefit. Nevertheless, although planting halophytes improves severely saline soil with low input costs, the recovery/accomplishment time (in saline soil improvement) cannot be as fast as that of engineering measures with much higher investment.

6.2 Main motivation of land users to implement SLM
- increased production
From the interview, farmers were satisfied with this technology of Sporobolus virginicus planting to rehabilitate severely saline soil. Besides being lower in salination farmers got more rice yields and better environment and livelihoods.
- reduced land degradation
After 3 years of planting Dixie grass, it was found that the formerly barren land became covered by plants and much improved in biodiversity by the evidence of many varieties of wild grass, dragonflies, small mammals and birds.
6.3 Sustainability of Approach activities
Can the land users sustain what has been implemented through the Approach (without external support)?
- yes
If yes, describe how:
Farmers have better understanding and positive attitude of planting halophytes (e.g. Dixie grass). Moreover, they have more income generated from rice yield and livestock, as farmers can now grow rice and used Dixie grass to raise livestock.
6.4 Strengths/ advantages of the Approach
Strengths/ advantages/ opportunities in the land user’s view |
---|
Soil doctor volunteer, local government agency and community leader were the coordinators in the area. |
Farmers had easy access to markets and sources of Dixie grass cuttings. |
Distribution of Dixie grass cuttings was done at no cost. |
Strengths/ advantages/ opportunities in the compiler’s or other key resource person’s view |
---|
A supported technique created to make better environment on severely saline soil in the Northeast of Thailand. |
Technique in planting Dixie grass was provided continually by Land Development Department and community volunteers on soil improvement. |
A demonstrated plot was established in the area. |
6.5 Weaknesses/ disadvantages of the Approach and ways of overcoming them
Weaknesses/ disadvantages/ risks in the land user’s view | How can they be overcome? |
---|---|
Advertising of project was not extensive enough, particularly to the area of severely saline soil. | It is necessary for the Land Development Department to cooperate more closely with local administration to promote the project. |
Weaknesses/ disadvantages/ risks in the compiler’s or other key resource person’s view | How can they be overcome? |
---|---|
Some farmers did not believe that Dixie grass was very salt tolerant and will make the salinity of the soil decrease after planting it. | The officers should build up knowledge from successful farmers by frequently visiting farmers in the area under the project "rehabilitation of severely salt-affected soil by planting Dixie grass". |
