2. Approach, aims, and enabling environment

Objectives of the technology

1. to prevent highly saline soil distribution

2. to utilize farmers' land to bring about most benefits
3. to use the grass as a cover crop and restore the ecosystem in areas with highly saline soil.

Activities and details of the operation

Planting halophytes has been supported from Land Development Department under the
project of promoting integrated development of areas with saline soil in sub-watershed areas and

activities of restoring areas with highly saline soil by growing salt resistant perennial plants and

halophytes. The stakeholders are officers working together with soil doctors and community
leaders in making public relations and coordinating the project work with farmers. Regional office

of Land Development Department has supported Dixie grass varieties based on compost, chemical
fertilizers to plant them on levees and the unused area with highly saline soil. Planting them on the

levee with the width of 1.5 meters and the plant spacing of 20x20 centimeters. They are
alternatively planted with Acacia auricuriformis with spacing between the trees of 2 meters. Dixie

grass propagation can be done by cutting the grass tree with the length of 2-3 inches for the number

of 3 nodes to be cultured in black bags. When the young plant is at the age of 1 month, it can be
cultivated. Using this technology has brought about changes within 3 years. Numerous types of
